The process of files being damaged because of some hardware or software failure is referred to as data corruption and this is among the main problems which hosting companies face since the larger a hard disk is and the more info is kept on it, the more likely it is for data to be corrupted. There're various fail-safes, still often the data gets corrupted silently, so neither the particular file system, nor the admins notice a thing. Consequently, a bad file will be handled as a standard one and if the HDD is a part of a RAID, the file will be duplicated on all other drives. In principle, this is for redundancy, but in practice the damage will be even worse. When some file gets damaged, it will be partially or entirely unreadable, which means that a text file will no longer be readable, an image file will show a random blend of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your site content. Although the most well-known server file systems have various checks, they quite often fail to find some problem early enough or require a long time period to check all the files and the hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Web Hosting

If you host your websites in a web hosting account with our company, you will not need to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform works with the amazing ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. All of the info that you upload will be kept in a RAID i.e. simultaneously on multiple NVMe drives. All file systems synchronize the files between the separate drives with such a setup, but there is no real guarantee that a file will not be corrupted. This may occur throughout the writing process on any drive and afterwards a corrupted copy can be copied on the other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all of the drives in real time and in case a corrupted file is identified, it's swapped with a good copy with the correct checksum from some other drive. That way, your data will stay undamaged 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 as the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. Since we keep all content on multiple 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. When there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that this happens in real time, there is no chance that a corrupted copy can remain on our website hosting servers or that it can be copied to the other drives in the RAID. None of the other file systems employ this kind of checks and furthermore, even during a file system check following an unexpected power failure, none of them can identify silently corrupted files. In contrast, ZFS doesn't crash after a power failure and the regular checksum monitoring makes a lenghty file system check obsolete.
