Data corruption is the unintended transformation of a file or the losing of info which often occurs during reading or writing. The reason may be hardware or software fail, and as a consequence, a file may become partially or completely corrupted, so it'll no longer work as it should as its bits will be scrambled or lacking. An image file, for example, will no longer display a true image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. If such a problem appears and it's not identified by the system or by an administrator, the data will be corrupted silently and if this happens on a drive that is part of a RAID array where the data is synced between various different drives, the corrupted file shall be replicated on all of the other drives and the damage will become long term. A large number of widespread file systems either do not have real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common matter on hosting servers where huge amounts of data are stored.

No Data Corruption & Data Integrity in Website Hosting

In case you host your sites in a website hosting account with our company, you do not need to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform uses the leading-edge ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. All the data that you upload will be stored in a RAID i.e. simultaneously on many different SSDs. 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 will not get corrupted. This can happen at the time of the writing process on any drive and afterwards a damaged copy can 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 in real time and in case a corrupted file is discovered, it's substituted with a good copy with the correct checksum from another drive. This way, your info will continue to be unharmed no matter what, even if a whole drive fails.
