Data corruption is the damage of information caused by various software or hardware fails. When a file is corrupted, it will no longer function accurately, so an app will not start or shall give errors, a text file could be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, which makes it a serious problem for hosting servers as problems are much more likely to happen on larger in size hard drives where substantial volumes of info are located. When a drive is part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the bad file will be treated as a standard one and it'll be copied on all of the drives, making the damage permanent. A huge number of the file systems which operate on web servers these days often cannot detect corrupted files instantly or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Web Hosting

If you host your Internet sites in a cloud web hosting account from our firm, you will not need to worry about any of your data ever getting damaged. We can ensure that as our cloud hosting platform works with the revolutionary ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each and every file. All the data that you upload will be saved in a RAID i.e. simultaneously on many NVMe drives. All of the file systems synchronize the files between the separate drives with such a setup, but there is no real warranty that a file won't get corrupted. This could happen at the time of the writing process on each drive and after that a bad copy may be copied on the other drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all drives live and if a corrupted file is discovered, it is swapped with a good copy with the correct checksum from some other drive. By doing this, your information will remain undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any probability of files getting corrupted silently due to the fact that the servers where your semi-dedicated server account will be created use a powerful file system known as ZFS. Its key advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we store all content on numerous NVMe 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 saved. When there's a mismatch, the bad copy is replaced with a good one from one of the other drives and since this happens right away, there's no chance that a damaged copy can remain on our web hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems use this type of checks and in addition, even during a file system check after an unexpected power failure, none of them will detect silently corrupted files. In comparison, ZFS does not crash after a blackout and the continual checksum monitoring makes a lenghty file system check unneeded.
