No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any risk of files getting corrupted silently due to the fact that the servers where your semi-dedicated server account will be created work with a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. As we store all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has stored. In the event that there is a mismatch, the bad copy is replaced with a good one from one of the other drives and because this happens in real time, there's no chance that a damaged copy can remain on our web servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems work with this type of checks and what is more, even during a file system check following an unexpected electrical power failure, none of them can detect silently corrupted files. In comparison, ZFS won't crash after a power loss and the regular checksum monitoring makes a lenghty file system check obsolete.
