Data corruption is the damage of data because of various hardware or software fails. After a file is corrupted, it will no longer function properly, so an application will not start or will give errors, a text file will be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, that makes it a significant problem for web hosting servers as problems are more likely to happen on larger hard disks where considerable volumes of information are placed. If a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it's likely that the bad file will be treated as a standard one and will be duplicated on all drives, making the harm permanent. A huge number of the file systems which operate on web servers these days often are unable to locate corrupted files right away or they need time-consuming system checks during which the server is not working.
No Data Corruption & Data Integrity in Shared Web Hosting
We warrant the integrity of the data uploaded in each shared web hosting
account that is created on our cloud platform because we use the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption using a unique checksum for each and every file. We shall store your info on a number of SSD drives which function in a RAID, so the exact same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file is different from what it should be, the file system swaps that file with an undamaged copy from another drive from the RAID. There's no other file system that uses checksums, so it's possible for data to get silently damaged and the bad file to be duplicated on all drives over time, but since this can never happen on a server running ZFS, you don't have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've 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 advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. As we store all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. If there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens right away, there's no chance that a corrupted copy can remain on our hosting servers or that it can be copied to the other hard disks in the RAID. None of the other file systems employ this kind of checks and what's more, even during a file system check right after a sudden blackout, none of them will find silently corrupted files. In comparison, ZFS won't crash after a power failure and the constant checksum monitoring makes a lenghty file system check unneeded.
