![]() After that, the porting ZFS to Linux starts. In the same year, porting to other operating systems began and by 2008, ZFS had been ported to FreeBSD. History of the ZFS file system evolutionĪfter the release of the ZFS file system, its source code was integrated into the Solaris operating system kernel. Using the copy-on-write method allows you to not use journaling at all and still be able to recover lost data.Īll these advantages and the great potential of ZFS are the reasons why so many people are still talking about it. Such a solution significantly increases the data recovery capabilities since you can always view the previous version of the files in case the information is corrupted. Then, instead of deleting the old files, the metadata that points to the new block is updated, and original information will only be deleted if there is insufficient disk space. Instead, a new block is allocated and a new copy is written inside. ![]() It means that when the file is overwritten it is not physically rewritten. It cannot be omitted that the ZFS file system uses copy-on-write technology. LVM technology is described in detail in the article “ LVM – what it is, advantages and disadvantages“. If you want to know more information about Linux RAID read the article “ RAID – what is it and which type is better to use“ For example, the ZFS somehow uses LVM (Volume Manager), Linux RAID (albeit a little modified), some XFS features, snapshots, and more. ![]() ZFS was able to pull together many solutions that are used in other file systems in isolation. In this way, the developers put a huge emphasis on its relevance in the future. In addition, it is 128-bit instead of the usual 64-bit. ZFS is very fast, technologically innovative, and effective. In 2005 the development team led by Matthew Arena and Jeff Bonwick introduced a file system that met all these requirements. In addition to this ZFS was supposed to offer redundancy. That is why it included a lot of innovations such as data layout structure, pooling support, and more.Įven the concept of a ZFS file system was innovative – ZFS needed to include a logical volume manager, provide convenient volume management and adhere to lightweight file system principles. Sun Microsystems wanted to create a new type of file system for their Solaris operating system, which would be ahead of its time. ![]() At the same time, performance should not be degraded, plus the ZFS file system had to have all the modern features. The main task for the developers of the ZFS file system was to create a modern file system that could work with huge amounts of data. The best alternatives to the ZFS file system.History of the ZFS file system evolution.In this article, we will look in detail at the ZFS file system. The main thing is to choose the correct file system for your needs. It can be used on desktops as well as on servers. The Linux operating system is quite flexible. ![]()
