Data corruption is the accidental modification of a file or the losing of information which often occurs during reading or writing. The reason could be hardware or software failure, and because of this, a file can become partially or completely corrupted, so it'll no longer work as it should because its bits will be scrambled or lost. An image file, for instance, will no longer show an actual image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In case such an issue appears and it is not recognized by the system or by an admin, the data will be corrupted silently and in case this happens on a disk drive that is part of a RAID array where the data is synced between various different drives, the corrupted file shall be copied on all other drives and the harm will be long term. Many widely used file systems either don't feature real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a very common issue on hosting servers where substantial amounts of info are kept.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your websites in a shared hosting account from our company, you will not have to worry about your data ever getting damaged. We can guarantee that as our cloud hosting platform works with the cutting-edge ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each and every file. All of the information that you upload will be stored in a RAID i.e. simultaneously on many different SSDs. Many file systems synchronize the files between the different drives using this kind of a setup, but there's no real guarantee that a file will not get corrupted. This can occur at the time of the writing process on any drive and afterwards a bad copy can be copied on all other drives. What is different on our platform is that ZFS compares the checksums of all files on all drives live and in case a corrupted file is located, it's swapped with a good copy with the correct checksum from another drive. By doing this, your info will continue to be undamaged no matter what, even if an entire drive fails.
