The process of files getting damaged caused by some hardware or software failure is referred to as data corruption and this is one of the main problems that hosting companies face since the larger a hard disk drive is and the more data is placed on it, the more likely it is for data to be corrupted. You will find various fail-safes, but often the information becomes corrupted silently, so neither the file system, nor the administrators detect a thing. Because of this, a corrupted file will be treated as a good one and if the hard drive is part of a RAID, that particular file will be copied on all other disk drives. Theoretically, this is done for redundancy, but in reality the damage will get even worse. When a given file gets damaged, it will be partly or fully unreadable, so a text file will no longer be readable, an image file will display a random mix of colors if it opens at all and an archive will be impossible to unpack, and you risk sacrificing your site content. Although the most popular server file systems feature various checks, they are likely to fail to discover some problem early enough or require a vast period of time to check all of the files and the hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Web Hosting

If you host your Internet sites in a cloud web hosting account with our firm, you won't have to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform uses the cutting-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any data that you upload will be kept in a RAID i.e. simultaneously on multiple NVMes. A lot of file systems synchronize the files between the separate drives with this type of a setup, but there's no real warranty that a file won't be corrupted. This may occur during the writing process on each drive and after that a bad copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all drives instantly and in the event that a corrupted file is identified, it is replaced with a good copy with the correct checksum from another drive. By doing this, your info will stay intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any chance of files getting damaged silently because the servers where your semi-dedicated hosting account will be created work with a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. As we save all content on numerous NVMe drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. In case there is a mismatch, the bad copy is replaced with a good one from one of the other drives and because this happens right away, there is no chance that a damaged copy can remain on our servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems work with this type of checks and what is more, even during a file system check following an unexpected power failure, none of them will detect silently corrupted files. In contrast, ZFS will not crash after a power loss and the regular checksum monitoring makes a lenghty file system check unnecessary.
