No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any risk of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. Since we keep all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has stored. If there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and considering that this happens instantly, there is no chance that a corrupted copy can remain on our web hosting servers or that it can be copied to the other hard drives in the RAID. None of the other file systems use such checks and what is more, even during a file system check right after an unexpected blackout, none of them will find silently corrupted files. In comparison, ZFS won't crash after a blackout and the regular checksum monitoring makes a time-consuming file system check unneeded.
