The process of files getting corrupted caused by some hardware or software failure is known as data corruption and this is among 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 become corrupted. You'll find several fail-safes, still often the info becomes damaged silently, so neither the file system, nor the administrators detect anything. Thus, a damaged file will be treated as a good one and if the hard disk is part of a RAID, the file will be copied on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will be worse. When a given file gets damaged, it will be partially or entirely unreadable, which means that a text file will not be readable, an image file will display a random blend of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most well-known server file systems feature various checks, they frequently fail to find a problem early enough or require a vast period of time to check all of the files and the server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Website Hosting

In case you host your websites in a cloud website hosting account from our firm, you do not have to worry about any of your data ever getting corrupted. We can ensure that as our cloud hosting platform uses the state-of-the-art ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on many different SSD drives. Many file systems synchronize the files between the different drives with this kind of a setup, but there is no real warranty that a file won't get corrupted. This can occur throughout the writing process on any drive and after that a damaged copy can be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all drives instantly and if a corrupted file is found, it's replaced with a good copy with the correct checksum from another drive. This way, your data will continue to be unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any possibility of files getting damaged silently as the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we store all content on a number of 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. In case there's a mismatch, the corrupted copy is replaced with a good one from one of the other drives and since this happens in real time, there is no chance that a corrupted copy can remain on our web hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems work with this type of checks and furthermore, even during a file system check following a sudden power failure, none of them can discover silently corrupted files. In comparison, ZFS does not crash after a power failure and the regular checksum monitoring makes a lenghty file system check obsolete.
