ZFS is one of the most sophisticated file systems nowadays and it outshines any other file system with regards to speed, functionality and stability. The speed at which information is processed on a web server using ZFS is greater, so not simply will any sites hosted on the hosting server be read and executed faster, but also backups could be generated a lot quicker and with greater frequency without affecting the overall performance. Furthermore, ZFS uses checksums - digital algorithms which are used to identify corrupted files. Whenever the file system finds that there is a problem with a specific file, it repairs it using a good copy from another hard disk within the RAID. Both the checks and the repairs are performed in real time, so the data located on ZFS-based web servers will be safe at all times since it practically cannot get corrupted. A different advantage of ZFS over other file systems is that there is no limit for the total amount of files which could be stored inside a single account or on the server as a whole.
