Data corruption is the damage of data because of various hardware or software problems. After a file gets corrupted, it will no longer work correctly, so an app will not start or will give errors, a text file will be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, that makes it a serious problem for web hosting servers as problems are very likely to happen on larger hard disks where vast volumes of info are kept. When a drive is a part of a RAID and the data on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as a good one and will be duplicated on all drives, making the harm permanent. A huge number of the file systems which run on web servers today often are unable to find corrupted files instantly or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Cloud Website Hosting

If you host your sites in a cloud website hosting account with our firm, you do not need to worry about your data ever getting damaged. We can guarantee that as our cloud hosting platform employs the cutting-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. All data that you upload will be stored in a RAID i.e. simultaneously on numerous SSDs. All file systems synchronize the files between the separate drives with this type of a setup, but there is no real warranty that a file won't be corrupted. This can happen at the time of the writing process on any drive and after that a damaged copy may be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all the drives right away and in the event that a corrupted file is identified, it's substituted with a good copy with the correct checksum from some other drive. By doing this, your info will remain undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created employ a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we store all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. If there's 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 is no chance that a corrupted copy could remain on our web hosting servers or that it could be duplicated to the other drives in the RAID. None of the other file systems use this kind of checks and what is more, even during a file system check after an unexpected electrical power failure, none of them can identify silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check unnecessary.
