The process of files getting corrupted owing to some hardware or software failure is known as data corruption and this is among the main problems that hosting companies face because the larger a hard disk is and the more info is kept on it, the much more likely it is for data to be corrupted. There are different fail-safes, still often the information becomes corrupted silently, so neither the file system, nor the admins see anything. Because of this, a damaged file will be treated as a standard one and if the hard drive is a part of a RAID, that file will be copied on all other disk drives. Theoretically, this is for redundancy, but in reality the damage will be worse. Once a file gets damaged, it will be partially or completely unreadable, which means that a text file will not 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, so you risk losing your content. Although the most commonly used server file systems feature various checks, they are likely to fail to discover a problem early enough or require a long period of time to be able to check all of the files and the web server will not be operational for the time being.

No Data Corruption & Data Integrity in Shared Hosting

If you host your sites in a shared hosting account with our firm, you don't need to worry about your data ever getting corrupted. We can ensure that due to the fact that our cloud hosting platform works with the cutting-edge ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. All info that you upload will be kept in a RAID i.e. simultaneously on many different SSDs. All of the file systems synchronize the files between the separate drives with this type of a setup, but there's no real guarantee that a file won't get corrupted. This can occur during the writing process on any drive and then a bad copy may be copied on all other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives live and in the event that a corrupted file is identified, it is substituted with a good copy with the correct checksum from another drive. This way, your information will continue to be undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any risk of files getting damaged silently as the servers where your semi-dedicated hosting account will be created employ a powerful file system named ZFS. Its main advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. As we store all content on multiple SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. In the event that there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because it happens right away, there is no chance that a damaged 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 this type of checks and what is more, even during a file system check right after an unexpected power loss, none of them will find silently corrupted files. In comparison, ZFS does not crash after a power loss and the regular checksum monitoring makes a lenghty file system check obsolete.
