Data corruption is the unintentional change of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software malfunction, and due to this fact, a file could become partially or completely corrupted, so it'll no longer work as it should as its bits will be scrambled or missing. An image file, for instance, will no longer show an actual image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In the event that such a problem occurs and it's not noticed by the system or by an administrator, the data will be corrupted silently and if this happens on a drive that's part of a RAID array where the info is synced between different drives, the corrupted file will be replicated on all of the other drives and the damage will be permanent. Numerous widespread file systems either do not offer real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a very common matter on hosting servers where substantial amounts of information are stored.
No Data Corruption & Data Integrity in Cloud Web Hosting
We warrant the integrity of the information uploaded in each cloud web hosting account which is generated on our cloud platform since we work with the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption through a unique checksum for each file. We shall store your info on multiple NVMe drives that work in a RAID, so identical files will be available on several places at once. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and in case the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged version from some other drive within the RAID. There's no other file system which uses checksums, so it is easy for data to become silently corrupted and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you will not have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any chance of files getting damaged silently since the servers where your semi-dedicated server account will be created take advantage of a powerful file system called ZFS. Its main advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we keep all content on numerous NVMe drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has stored. In the event that there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and because it happens in real time, there's no chance that a damaged copy could 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 use such checks and what's more, even during a file system check after an unexpected power loss, none of them can detect silently corrupted files. In contrast, ZFS does not crash after a blackout and the regular checksum monitoring makes a time-consuming file system check obsolete.
