XFS is better larger files and long-term maintaince and stability. Quota journaling: This avoids the need for lengthy quota consistency checks after a crash. Ext3 and ext4 have some very specific differences, which I'll focus on here. I am getting too many input/output errors with my 3TB HDD NTFS hard disk for main files. The main thing is to use latest Linux kernels to avoid old kernel Btrfs implementation. Out of Ext4 or btrfs, I would chose btrfs with the snapshots. ZoL Performance, Ubuntu ZFS On Linux Reference Storage : 2019-04-24: Linux 5. BTRFS is newer, and the performance is not as good in many cases, but it is not far off. But EXT4 is mature, rock solid, and completely reliable, and the standard for most of the linux world. Boot from an install CD, then convert by doing: # btrfs-convert /dev/ partition. petronasAMG77 • 1 yr. Each of the tested file-systems were carried out with the default mount options in an out-of-the-box manner. btrfs sub cr /mnt/@ (the @ alone is the convention for "root directory" in btrfs) btrfs sub cr /mnt/@home. Yes Ext4 is much easier to setup but BTRFS has its advantages. This is because BTRFS is optimized for handling small files, while EXT4 can struggle with multiple small files due to its delayed allocation. I can't make out whether this will remove hot spots when the underlying raid device changes, but a plain rebalance will rewrite the entire file system, so it looks like it will. It supports all. I'ved tested compress=off/lz4, dedup=on/off and serveral Cache/Log constellations on 256GB SSD. Linux vs. Both Btrfs and Ext4 have their own advantages. 가능. 7 - EXT4 vs. Perhaps btrfs is much better for SSDs, but in oldschool HDDs I. An anonymous reader writes "Phoronix has published Linux filesystem benchmarks comparing XFS, EXT3, EXT4, Btrfs and NILFS2 filesystems. ) XFS. One of the main reasons the XFS file system is used is for its support of large chunks of data. xfs command. ext4. Be sure to change the /etc/fstab to reflect the change ( type to btrfs and fs_passno [the last field] to 0 as Btrfs does not do a file system check on boot). I think in many ways btrfs is the better filesystem, but I seem to have noticed that it takes longer to copy data than on ext4. Btrfs uses Copy-on-Write (COW), a resource management technique where a. 10. Ext4 and XFS are the fastest, as expected. BTRFS VS EXT4 performance in Raid 1. If you are using Ext2 or Ext3, you can convert the partition to Ext4. Ext4 and XFS are the fastest, as expected. 15 Git kernels. jkool702. The arguments about ext4 vs NTFS have been raging online for decades now. Here are a few other differences: Features: Btrfs has more advanced features, such as snapshots, data integrity checks, and built-in RAID support. ZFS & BTRFS (and maybe BCACHEFS) present an entirely new and generally superior paradigm. This article provides a detailed comparison of XFS vs btrfs to help you determine which file system is a better fit for your use case. Ext4 fs can read and write to Ext2 or Ext3 file systems, but the Ext4 it is not compatible with Ext2 and Ext3 drivers. As modern computing gets more and more advanced, data files get larger and more. (For example, you might have an ext4 root filesystem, but store most of your data on a zfs or btrfs pool. Per the recommendation from RedHat: Another way to characterize this is that the Ext4 file system variants tend to perform better on systems that have limited I/O capability. F2FS vs. A backup strategy without data integrity protection from the file system or some other mechanism will blindly backup corrupted data if data corruption occurs. Across the three tested RAID modes, EXT4 was performing the worst. But. In this tutorial, we will check Btrfs against Ext4 filesystem, and seek to understand their functionalities, strengths, and weaknesses. While I have used btrfs balanced, timeshift and my other develop tool scripts for managing borg backups rely a lot on standard linux file. EXT4. Windows has always been terribly slow to update, say, all file permissions in a large directory structure. 3 XFS. The stock mount options were used for all of the testing. Thanks! In that case, your choice is simple. Die Funktionen umfassen eine transparente Komprimierung, Prüfsummen und. XFS A number of Phoronix readers have been asking about some fresh file-system comparisons on recent kernels. Granted, i just use the automatic partition creater at setup, so it still uses ext4 for the /boot and /boot/efi partitions. " And it can be much faster than btrfs, especially with lots of smaller files. my rough draft would be to offer an advanced option for the mount points (i. Another way to characterize this is that the Ext4 file system variants tend to perform better on systems that have limited I/O capability. The only concern I have is performance, maybe btrfs in a HDD will be really slow. EXT4 vs. EXT4は、Linuxベースのオペレーティングシステムのメインファイルシステムです。Complexity: btrfs is a more complex file system than ext4, and may require more advanced knowledge and expertise to manage and maintain. Let’s go through the different features of the two filesystems. Picking a filesystem is not really relevant on a Desktop computer. All my systems (4) have been using BTRFS for some time now without any issues. Hi I have used BTRFS for the first time since March 2023 on my internal archives directory. Ext4 file systems. org and zfsonlinux. Both are good file systems. Ext4 was designed with spinning drives in mind but as SSDs are fundamentally different, an SSD optimized file system can help. Btrfs vs Ext4. To reserve an external journal with a specified size when you create an XFS file system, specify the -l logdev=device,size=size option to the mkfs. From some of the recent Linux kernel patches, it seems some of the most popular Linux file systems, Flash-Friendly File System (F2FS), B-Tree Filesystem (Btrfs), and fourth extended filesystem. And ext3. btrfs has the "btrfs-balance" command. Quota journaling: This avoids the need for lengthy quota consistency checks after a crash. 두 파일. Reliable! I used it in Rsync mode as only my backup disk is btrfs, everything else was ext4 or XFS. FYI: btrfs. The ext4 file system is still fully supported in Red Hat Enterprise Linux 7 and can be selected at installation. We currently recommend XFS for production deployments. But I was more talking to the XFS vs EXT4 comparison. ext4 with m=0 ext4 with m=0 and T=largefile4 xfs with crc=0 mounted them with: defaults,noatime defaults,noatime,discard defaults,noatime results show really no difference between first two, while plotting 4 at a time: time is around 8-9 hours. 10 4. repeat with all candidate filesystems in my case it was ext3, XFS, ReiserFS and JFS. But EXT4 is mature, rock solid, and completely reliable, and the standard for most of the linux world. Linux File-systems were tested on NVMe SSD including EXT3, BTRFS, EXT4, XFS, and ZFS from the mainline kernel of Linux 4. Agree, actually I have a bunch of freebsd for ZFS. Vide. Btrfs, ZFS, and bcachefs are probably your best bets out of the 19 options considered. Note that while these tests are not indicative of real-world performance, we can extrapolate these results and use this as one reason. X percent… The more modern filesystems of BTRFS and ZFS not only have data integrity features but also the inline compression pushes the efficiency past 100% in many cases. This includes workload that creates or deletes large numbers of small files in a single thread. On a slow Linux box with an ext4 filesystem, the same operation takes less than a second. 7 - EXT4 vs. 4 EXT4 / XFS / Btrfs RAID Performance On Four HDDs Storage : 2019-12-28: Benchmarking The Experimental Bcachefs File-System Against Btrfs, EXT4, F2FS, XFS & ZFS Storage : 2019-06-25: Optane SSD RAID Performance With ZFS On Linux, EXT4, XFS, Btrfs, F2FS Storage : 2019-06-20: Linux 5. Though personally I'd still go with ext4 primarily because despite recognizing some potential benefits of btrfs, I really don't see them as important for how I use my computers. A File system is one of the most important aspects that af. Updating 1 million files takes ages. Mount the partition and test the conversion by checking the files. This page is powered by a knowledgeable community that helps you make an informed decision. Ability to create large volumes of up to 1 PB 1. In Summary, ZFS, by contrast with EXT4, offers nearly unlimited capacity for data and metadata storage. 5. To mount the XFS file system so that it uses the external journal, specify the -o logdev=device option to the. I understand if I use zfs/btrfs i will miss out on any data redundancy features but maybe pick up some added features like better consistency, snapshots, ect or should I just stick with ext4. EXT4 es el sistema de archivos más utilizado en sistemas operativos basados en Linux, este sistema de. BTRFS have some fancy features, and could help you manage your disk better in some automation-future-proof way. 对于一些文件系统如Ext4等，在硬盘格式化时就全部确定了，而对于XFS则是动态生成的，BtrfS则是更特别的动态实现。. I wouldn't go for ZFS on root although it is fully supported on Proxmox 6. Same could be said of reads, but if you have a TON of memory in the server that's greatly mitigated and work well. File-systems tested on the NVMe SSD included Btrfs, EXT4, F2FS, XFS, and NTFS. 7. It was later developed for Linux. As others have said, btrfs is newer and offers a few advanced features for backups (snapshots) and data integrity. On the other hand BTRFS, while mainlined, has many important issues and performance problem (the common suggestion for databases or VMs is to disable CoW which, in turn, disabled checksumming - which is, frankly, not an acceptable answer). For the most. that said, current Tumbleweed builds disable COW for those subvolumes. We’ll go over each file system in more detail ahead. On multi-drive systems, the opposite might be true, zfs outperforming ext4. Moreover, the ext4 is more beneficial when the. Xfs is very opinionated as filesystems go. However, when we review EXT4 vs BTRFS, here’s the downside: BTRFS has disk and volume management built-in, while EXT4 is a “pure filesystem”. Btrfs使用校验和来确保数据不会被破坏，另一方面，Ext4不能确保数据的完整性。 Btrfs提供了文件系统中存在的压缩算法，允许在将数据写入系统时在文件系统级进行压缩. Not just permissions, but moving them or getting file sizes, too. The preferable option depends on your specific needs and priorities. 3 which makes XFS v5 the default and all the benefits it brings. My problem is that in some games when DXVK is running in Linux, stutters occur, although there are no such problems on Windows. Written by Michael Larabel in Storage on 20 January 2018. Ext4 focuses on providing a reliable and stable file system with good performance. Its not faster or more stable then the other two. However, to be honest, it’s not the best Linux file system comparing to other Linux file systems. Btrfs（技术预览）" Collapse section "6. @taffer Your "recent benchmark" is from April 2015, over three years old and uses XFS with only default options. 15 kernel can see our dozens of articles covering this. creating volumes and mounting them would need to check that option and decide on appropriate mount points. In summary, both Btrfs and Ext4 are good options for your NAS, and the choice between the two ultimately depends on your specific needs and use case. Data integrity protection. 7 - EXT4 vs. This is the first time that the new EXT4 and Btrfs and NILFS2 filesystems have been directly compared when it comes to their disk performance though the results may surprise. EXT4 had the best speed at 58MB/s while Btrfs came in slightly behind that at 52MB/s and then ZFS came in at 46MB/s. BTRFS bietet, mal abgesehen von der Möglichkeit einer Inline Deduplizierung, beinahe alle Features von ZFS. It lived enough, time to move on. I have a raid 1 setup on dual 3. A Red Hat training course is available for RHEL 8. Btrfs provides checksums for data and metadata, ensuring enhanced data integrity. If you're looking to warehouse big blobs of data or lots of archive and reporting; then by all means ZFS is a great choice. Ext4: cũng giống như Ext3, lưu giữ được những ưu điểm và tính tương thích ngược với phiên bản trước đó. 0 SSD drive used was a 250GB Samsung 850 PRO solid-state drive connected both via SATA and then a SATA. Perhaps btrfs is much better for SSDs, but in oldschool HDDs I. 7. 240GB SSD formatted as EXT4 for main OS. 4. But. Bảo vệ dữ liệu. The SATA 3. So please enlighten me, where is btrfs better and where is it worse or just significantly different than ZFS. 5. XFS does not require extensive reading. Granted, i just use the automatic partition creater at setup, so it still uses ext4 for the /boot and /boot/efi partitions. 0 File-System Benchmarks: Btrfs vs. 0. ZFS is open source, it isn't "owned" by Oracle. This is the number of data disks times the number of blocks per. Diferenças básicas entre o Ext4 e o Btrfs. Btrfs supports RAID 0, 1, 10, 5, and 6, while ZFS supports various RAID-Z levels (RAID-Z, RAID-Z2, and RAID-Z3). 1 fell slightly short of the Linux file-system performance. Btrfs is not a successor to the default Ext4 file system used in most Linux distributions, but it can be expected to replace Ext4 in the future. In the past, I have often seen statements that EXT4 is better for gaming than XFS. Được tích hợp vô hệ thống DSM Synology , do NAS có hiệu xuất làm việc cao trong vấn đề lưu trữ và khôi phục, Btrfs hoạt động trên NAS. After a week of testing Btrfs on my laptop, I can conclude that there is a noticeable performance penalty vs Ext4 or XFS. Seeking around those files which a DB will do may yield different. XFS for data, because XFS is a damn good filesystem for data and doesn't have the few edge cases that btrfs does where it sometimes isn't the best filesystem for certain profiles for example, databases, lots of tiny writes have a sometimes will slow down a btrfs filesystem. For anything with higher capability, XFS tends to be faster. It's a 64-bit, journaling filesystem that has been built into the Linux. But according to tests in all scenarios, XFS is better than EXT4, it's a pity that there are no tests in games. Hey Guys! Welcome to XPSTECH. Just EXT4, yes. EXT4 had the best speed at 58MB/s while Btrfs came in slightly behind that at 52MB/s and then ZFS came in at 46MB/s. In terms of XFS vs Ext4, XFS is superior to Ext4 in the following. Overview of File Systems in Linux. And xfs. I have 6 disks so I have created 3 logical disks, 2 SSDs each - just for testing. Features of the XFS and ZFS. xfs 4 threads: 97 MiB/sec. A continuación, os vamos a explicar brevemente las principales características de EXT4 y de Btrfs. ZFS also has more options for caches and such things than EXT4. ran btrfs balance to balance all btrfs volumes. Approach 2: Readjust things so the kernel and modules are on an ext4 filesystem and the data you most want to compress is on a btrfs partition. . Ext4 Filesystem 其實你提到一個重點了. Each of the five file-systems were tested on the same NVM Express SSD from the Linux 4. Delay allocation. Tenga en cuenta que el uso de inode32 no afecta a los inodos que ya están asignados con números de 64 bits. But timeshift reports (maybe due to different sizes of the combined btrfs) as reported in my initial. Under Compile Bench, EXT4 was the fastest on all three drives followed by a mix of XFS and F2FS. Edit: fsdump / fsrestore means the corresponding system backup and restore to for that file system. Unix, etc. Btrfs on SSD, XFS on HDD. However, the performance of ZFS on FreeBSD/PC-BSD 8. It's a mature filesystem and offers online defragmentation and can. If you are concerned about your data integrity, as you clearly are, then use ZFS. File-systems tested on the NVMe SSD included Btrfs, EXT4, F2FS, XFS, and NTFS. NTFS OpenBenchmarking. Now I may send the snapshots also to an local device (formatted in Btrfs). 8. Have snapper to create pre/post BTRFS and LVM snapshots. Pros: Individual file size: 16GB to 2TB. And generally, files that arent compressible, wont be forcefully compressed. If you are looking for advanced features such as data checksumming, snapshots, and data deduplication, then Btrfs may be the better option. Probably those edge cases are not visible on an external USB hard drive, could be visible with external SSDs on a USB3. You might also want to consider Btrfs for your array drives, but you should be aware of the potential risks. It utilizes a b+tree structure instead of the traditional linear layout found in most filesystems today, allowing it to better manage larger datasets more efficiently than other systems like ext4 or Xfs. Because of that, the Ext4 file system is very stable. 1 million iops for ext4, right in line with the spec of the drive times 2,. Btrfs, EXT4, XFS, F2FS, and NILFS2 were tested on a Linux 5. A continuación, os vamos a explicar brevemente las principales características de EXT4 y de Btrfs. This correlates with the previous experiment and the hypothesis. Does that mean that if I'm using btrfs snapshots, it will not save parity data for any snapshots other than the current state of the drive, that it will only save parity data for one snapshot other than the current state of the drive, or that it will fail entirely?ZFS can also send and receive file system snapshots, a process which allows users to optimize their disk space. 또한 ext3. - No RAID. ) TL, DR: All 3 major next gen CoW file systems have their advantages and drawbacks, and I figure integrating them into my workflow is the only way to fairly evaluate them see how they work for myself. Ext4 is a journaled filesystem, which simply means that it “journals” the location of the files on the disk and keeps track of the changes on the disk. The result of XFS is often more than three times lower than ZFS in this benchmark, and the difference with Btrfs and EXT4 is greater. I think in many ways btrfs is the better filesystem, but I seem to have noticed that it takes longer to copy data than on ext4. Die Benchmark-Testergebnisse zeigten, dass BTRFS etwas niedrigere Lese- und Schreibgeschwindigkeiten als EXT4 hatte. Ext4, while. • 3 mo. XFS is about as mainline as a non-ext filesystem gets under Linux. With Btrfs you get self healing, snapshots, copy on write, background file system checks, online defragmentation, and much more. FreeBSD has ports you can install that will allow data transfer of some linux file systems. 1 million iops for ext4, right in line with the spec of the drive times 2,. ext3 is the most common format. Furthermore, the Ext4 is designed to be backward compatible. 6. Theodore Ts’o, a maintainer for Ext3 and later, Ext4, has stated that he sees Btrfs as a better way forward than continuing to rely on the ext* technology. To be clear, I am using RAID0 with two SSDs with strip size of 256Kb. I'd say ext, because it is faster, and because you asking means, that you don't know how to use btrfs features, otherwise the choice is obvious: need snapshots -> btrfs, need reflinks -> XFS, default -> ext4. 0 File-System. The only benefit of btrfs that I could find was marginally easier setup and the software license. g. buying used laptops with older ssd vs a new one. The Ext4 file system is a very old file system and it has been used on the Linux operating system for a long, long time. F2FS vs. As well as ext4. Increased Performance of ext4 vs. As for filesystems, not sure I'd bother considering JFS since I believe it may be deprecated out of the kernel soon. with mirrored pairs, you also have the option of. Đảm bảo dữ liệu khi backup. Ext4 and XFS are both great for "I need a filesystem, to store files, on this drive". In most cases that’s EXT4, but for Fedora, OpenSuse and maybe a few others it’s btrfs. Moreover, the ext4 is more beneficial when the. Btrfs El sistema de archivos Btrfs nació como sucesor natural de EXT4, su objetivo es sustituirlo eliminando el mayor número de sus limitaciones, sobre todo lo referido al tamaño. 0 File-System Benchmarks: Btrfs vs. 84 nvme drives split up into a small ext4 volume and the rest is btrfs. Utilice. Btrfs lacks maturity and stability at the time of this writing but is more feature-rich compared to EXT4. 4. Una vez que hemos conocido las principales características de EXT4, vamos a hablar sobre Btrfs, el que se conoce como sucesor natural del sistema de archivos EXT4. 3. In the case of the Intel 900p SSD, the XFS results were too fast to accurately measure while EXT4 and F2FS took just two seconds to complete while Btrfs took six seconds. XFS, EXT4, and BTRFS are file systems commonly used in Linux-based operating systems. F2FS, XFS, ext4, zfs, btrfs, ntfs, etc. ran defragment utility to compress all existing files. F2FS vs. Let's go over File Systems in this video. Running this fio command, I get about 2. Ext3 and Ext4 perform better on limited bandwidth (< 200MB/s) and up to ~1,000 IOPS capability. In most cases that’s EXT4, but for Fedora, OpenSuse and maybe a few others it’s btrfs. At least on 13. Reasons why I avoided btrfs:Btfs not meant to replace ext4, they are in a different category, ext4 is simple, old and stable while btrfs brings new ideas and goes into very different direction. Silent data corruption, sometimes referred to as bitrot, is more. My home file share runs zol because I prefer zfs to btrfs and run it at work a lot so I'm much more comfortable with it. . Ext4中没有这种内置的压缩支持。 Btrfs直接从磁盘删除重复数据，而Ext4不能这样做， Btrfs支持. Why? Files are the most important bits of data on your hard drive. The PostgreSQL database server ran well particularly on EXT4 and XFS while F2FS on the USB 3. Both Btrfs and ZFS offer built-in RAID support, but their implementations differ. 1 only) xfs (RHEL 7. Fwiw, I think XFS still handles huge files better than EXT, so there are reasons to use it. yield a very fast imaging backup. ext4 4 threads: 74 MiB/sec. Starting with Red Hat Enterprise Linux 7.

With not having the time to conduct the usual kernel version vs. For reducing the size of a filesystem, there are two purported wats forward, according to xfs developers. The fourth generation File System of the Ext (Extended) file system family. OMV supports btrfs but you still have to scrub etc yourself from the command line. It supports large file systems and provides excellent scalability and reliability. In the future, Linux distributions will gradually shift towards BtrFS. BTRFS was clearly in the lead when considering Documents – even better than ZFS with deduplication. 현재 Ext4는 Red Hat Enterprise Linux 6의 기본 파일 시스템으로 단일 파일 및 파일 시스템 모두에서 최대 16 TB 크기 까지 지원합니다. Ext4 파일 시스템. It's a filesystem which resides entirely in your RAM. Regarding boot drives : Use enterprise grade SSDs, do not use low budget commercial grade equipment. 4 EXT4 / XFS / Btrfs RAID Performance On Four HDDs Storage : 2019-12-28: Benchmarking The Experimental Bcachefs File-System Against Btrfs, EXT4, F2FS, XFS & ZFS Storage : 2019-06-25: Optane SSD RAID Performance With ZFS On Linux, EXT4, XFS, Btrfs, F2FS Storage : 2019-06-20: Linux 5.

F2FS vs. As others have said, btrfs is newer and offers a few advanced features for backups (snapshots) and data integrity. On the other hand, backup of xfs to xfs allows you certain features that. Ceph's recommendation for the choice of filesystem is between btrfs and XFS. - Linux Kernel 5. ZFS brings robustness and stability, while it avoids the corruption of large files. While looking at the filesystem options it seems like BTRFS is a lot more stable than it was the last time I had to install arch so now I am seriously considering using it. 0-040700-generic (x86_64) Unity 7. Recommended for general use. The SATA 3. Approach 1: Build your own kernel, and tweak it's build config to pre-link btrfs. My problem is that in some games when DXVK is running in Linux, stutters occur, although there are no such problems on Windows. It uses a default file system for Linux distribution, including Debian and Ubuntu. use ZFS only w/ ECC RAM. Features of the XFS and ZFS. zfs not. So now I can boot up into a snapshot. Benchmarking The Experimental Bcachefs File-System Against Btrfs, EXT4, F2FS, XFS & ZFS Storage : 2019-06-25: Bcachefs Linux File-System Benchmarks vs. all kinds for nice features (like extents, subsecond timestamps) which ext3 does not have. Journaling ensures file system integrity after system crashes (for example, due to power outages) by keeping a record of file system. XFS 和 ext4 的比较. EXT4 vs. However, we also must admit that Btrfs has many advantages that Ext4 doesn’t have, for example: The question is XFS vs EXT4. But unless you intend to use these features, and know how to use them, they are useless. A tool for managing BTRFS and LVM snapshots. 88. A daily snapshot of Ubuntu 19. XFS scales much better on modern multi-threaded workloads. Rather then using BTRFS, I would use XFS and hope for the best, or using dm-integrity. 7-rc1 Released With NVIDIA GSP & Bcachefs While Itanium IA-64 Retired Linux Kernel :. But none of these will be relevant to a bog standard use case like "browsing the internet and sometimes. I've read and have anecdotally (not scientific and could be affected by other things) experienced Btrfs being slower than ext4. Linux File System Comparison: XFS vs. ago. How do the major file systems supported by Linux differ from each other?The major difference between ext4 and XFS file systems is that the ext4 file system works better for fewer size files (single write/read thread) while the XFS works more efficiently for larger files (multiple read/write threads). I remember being on ext4 using Timeshift but it only supports rsync–so slow. It takes a second to snapshot, and deletes of a snapshotted tree what takes ext4 26 hours is a few minutes on btrfs. 另外，我们常说的file对象，它用于关联进程和dentry对象的. Btrfs is a more modern file system, introduced in 2007. But according to tests in all scenarios, XFS is better than EXT4, it's a pity that there are no tests in games. both have hidden sharp edges, work differently, and have different design philosophies in terms of the command line tools etc. (當然另一種做法是新增硬碟, 另外格式化為 btrfs. Even if you do notice. It does its job well. The XFS File System. 4 EXT4 / XFS / Btrfs RAID Performance On Four HDDs Storage : 2019-12-28: Benchmarking The Experimental Bcachefs File-System Against Btrfs, EXT4, F2FS, XFS & ZFS Storage : 2019-06-25: Optane SSD RAID Performance With ZFS On Linux, EXT4, XFS, Btrfs, F2FS Storage : 2019-06-20: Linux 5. Neither of the filesystems is better supported by OMV4 or OMV5. It is the default file system in RHEL 6, Debian 7, Ubuntu 18 and so on. Depending on why you want btrfs, you could run zfs. But. That one is solid and mature. There won't be any noticeable difference. btrfs was slower and had reliability problems. 2. We recommend btrfs for testing, development, and any non-critical deployments. The Ext4 File System. ext4 was supposed to be a stop gap until a better Linux filesystem came along. Now I may send the snapshots also to an local device (formatted in Btrfs). 无论您选择哪个文件系统，都要确保进行适. It was later developed for Linux.
