Data corruption is the accidental transformation of a file or the losing of info that often occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file may become partially or entirely corrupted, so it'll no longer work as it should because its bits will be scrambled or lacking. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. When this kind of an issue occurs and it's not noticed by the system or by an administrator, the data will become corrupted silently and in case this happens on a drive that's part of a RAID array where the info is synchronized between various different drives, the corrupted file shall be replicated on all the other drives and the harm will be long term. A large number of popular file systems either do not offer real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a common matter on web hosting servers where substantial amounts of information are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

If you host your websites in a shared web hosting account from our firm, you do not need to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform employs the revolutionary ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on a large number of NVMe drives. All file systems synchronize the files between the separate drives using this kind of a setup, but there is no real guarantee that a file will not be corrupted. This can happen during the writing process on each drive and then a corrupted copy may be copied on all other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all of the drives right away and in case a corrupted file is located, it is substituted with a good copy with the correct checksum from another drive. In this way, your info will stay unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any probability of files getting damaged silently as the servers where your semi-dedicated server account will be created employ a powerful file system called ZFS. Its basic advantage over various 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 NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. If there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and considering that it happens right away, there is no chance that a corrupted copy can remain on our hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems use such checks and in addition, even during a file system check following a sudden power failure, none of them will detect silently corrupted files. In comparison, ZFS won't crash after a power failure and the continual checksum monitoring makes a time-consuming file system check obsolete.
