The process of files being corrupted as a consequence of some hardware or software failure is called data corruption and this is among the main problems which web hosting companies face because the larger a hard drive is and the more info is kept on it, the much more likely it is for data to get corrupted. You'll find various fail-safes, but often the info gets corrupted silently, so neither the particular file system, nor the administrators notice a thing. Thus, a damaged file will be handled as a standard one and if the hard disk is a part of a RAID, that file will be copied on all other disk drives. In principle, this is done for redundancy, but in reality the damage will get worse. When some file gets damaged, it will be partly or entirely unreadable, therefore a text file will no longer be readable, an image file will display a random blend of colors in case it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your website content. Although the most commonly used server file systems include various checks, they quite often fail to detect some problem early enough or require an extensive amount of time to be able 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
If you host your Internet sites in a cloud website hosting account with our firm, you do not have to worry about any of your data ever getting corrupted. We can guarantee that since our cloud hosting platform uses the cutting-edge ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on a number of SSD drives. All the file systems synchronize the files between the different drives with this type of a setup, but there is no real warranty that a file won't be corrupted. This can occur during the writing process on any drive and then a bad copy may be copied on the other drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all drives live and in case a corrupted file is located, it is swapped with a good copy with the correct checksum from some other drive. This way, your data will remain undamaged no matter what, even if a whole drive fails.
