![]() ![]() In addition to that, both ZFS and OpenZFS file systems support several compression algorithms, allowing users the option of enabling or disabling inline data compression.ĭelegated Permissions and Tighter Access Control. Since security is an ever-growing issue among organizations today, one can appreciate how both ZFS and OpenZFS file systems feature relegated permissions and finer-grained access control lists. Inline Data Compression. ZFS and OpenZFS file systems use inline data compression as a built-in feature to reduce the number of bits required to store data. Lastly, ZFS snapshots and clones are beneficial as a recovery tool in the event of a ransomware attack. With ZFS on Solaris, snapshots and clones are integrated into boot environments and allow users to conduct a rollback of previous snapshots in the event something goes wrong while updating or patching a system. Snapshots are considered immutable copies (data is replaced rather than changed), while clones are mutable (data is modified and updated in-place regularly). ZFS and OpenZFS file systems are capable of producing point-in-time copies of file systems quite fast and efficiently since the system preserves all copies of the data. ZFS Send/Receive. ZFS and OpenZFS users can take a “snapshot” of the file system so that its image can be sent to different server nodes, allowing data from that image to be replicated to separate systems for the purpose of backing up data or data migration to the cloud. For this reason, ZFS file systems are highly scalable, supporting large maximum file sizes if the system requires additional capacity, users only need to add more drives to the network. It can do this on a solitary network while pooling all available storage as though it existed within one huge NAS drive. On the other hand, the redirect-on-write file system (particularly the ZFS file system) updates the metadata so that it points-redirects-towards the newly written blocks.īy design, ZFS is capable of managing hundreds and even thousands of network-attached storage (NAS) drives on one network. The copy-on-write file system overwrites original data blocks after reproducing an exact copy in a new location. The distinctions between the two file system types lie in how they both handle original blocks of data after duplicating them. Though it’s commonly referred to as a copy-on-write file system, Oracle defines it appropriately as being a redirect-on-write file system. ![]() This very unique storage system is a combination of a file system and a logical volume manager (LVM), which means it handles both the physical aspect of data storage (such as hard disk drives) and its volumes (it’s logical arrangement into volumes, all the files stored within those volumes, as well as their status and condition). The truth of the matter is, ZFS doesn’t stand for anything. ZFS was once given the backronym Zettabyte File System in an attempt to give a non-word meaning. A Short Guide About ZFS: The Last Word In File Systems February 11, 2020Īs insignificant as it sounds, there is a lot of responsibility that comes with being the last word in file systems. ![]()
