The process of files getting corrupted as a consequence of some hardware or software failure is called data corruption and this is among the main problems which hosting companies face since the larger a hard disk drive is and the more info is filed on it, the much more likely it is for data to be corrupted. There are a couple of fail-safes, but often the data gets damaged silently, so neither the particular file system, nor the administrators detect a thing. Consequently, a damaged file will be handled as a regular one and if the hard drive is part of a RAID, that particular file will be copied on all other drives. In theory, this is done for redundancy, but in reality the damage will be even worse. The moment some file gets damaged, it will be partially or entirely unreadable, so a text file will no longer be readable, an image file will show a random mix of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your website content. Although the most commonly used server file systems feature various checks, they are likely to fail to find a problem early enough or require a long amount of time in order to check all files and the web hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Web Hosting

We guarantee the integrity of the info uploaded in each and every web hosting account which is made on our cloud platform because we work with the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption via a unique checksum for each file. We'll store your information on a large number of SSD drives that function in a RAID, so exactly the same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and if the checksum of any file differs from what it needs to be, the file system swaps that file with a healthy version from some other drive inside the RAID. No other file system uses checksums, so it's easy for data to become silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you do not have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any probability of files getting damaged silently since the servers where your semi-dedicated server account will be created work with a powerful file system known as ZFS. Its 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 SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has stored. When there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and because it happens in real time, there is no chance that a corrupted copy can remain on our web servers or that it can be copied to the other hard disks in the RAID. None of the other file systems include this kind of checks and what's more, even during a file system check right after an unexpected blackout, none of them will find silently corrupted files. In contrast, ZFS doesn't crash after a blackout and the constant checksum monitoring makes a time-consuming file system check unneeded.
