The process of files getting damaged owing to some hardware or software failure is called data corruption and this is among the main problems that Internet hosting companies face as the larger a hard disk drive is and the more info is stored on it, the much more likely it is for data to be corrupted. There're various fail-safes, yet often the information is damaged silently, so neither the particular file system, nor the admins notice a thing. Consequently, a corrupted file will be treated as a good one and if the hard disk is part of a RAID, that file will be copied on all other drives. In theory, this is for redundancy, but in reality the damage will be even worse. Once some file gets damaged, it will be partly or entirely unreadable, which means that a text file will not be readable, an image file will show a random combination of colors if 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 feature various checks, they frequently fail to find a problem early enough or require a long amount of time in order to check all files and the server will not be functional in the meantime.
No Data Corruption & Data Integrity in Web Hosting
If you host your websites in a web hosting account from our company, you do not have to worry about any of your data ever getting corrupted. We can guarantee that as our cloud hosting platform employs the state-of-the-art ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on many different SSD drives. All the file systems synchronize the files between the separate drives using this type of a setup, but there is no real warranty that a file won't get corrupted. This can occur throughout the writing process on each drive and then a corrupted copy may be copied on all other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all the drives instantly and in case a corrupted file is located, it is swapped with a good copy with the correct checksum from another drive. That way, your info will continue to be intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not experience any kind of silent data corruption issues whatsoever if you buy one of our semi-dedicated hosting packages since the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all the files are undamaged all of the time. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Because we store all content on multiple drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. When it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any probability of the damaged copy to be synchronized on the remaining drives. ZFS is the sole file system available on the market that uses checksums, which makes it far superior to other file systems which are not able to detect silent data corruption and copy bad files across drives.
