Data corruption is the accidental transformation of a file or the loss of information which usually occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file could become partially or fully corrupted, so it will no longer function properly since its bits will be scrambled or lacking. An image file, for instance, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In the event that such an issue occurs and it is not found by the system or by an admin, the data will get corrupted silently and when this happens on a drive that's part of a RAID array where the information is synchronized between various drives, the corrupted file shall be copied on all the other drives and the damage will become permanent. Many widespread file systems either do not have real-time checks or do not have good ones that will detect an issue before the damage is done, so silent data corruption is a common problem on web hosting servers where huge amounts of information are kept.
No Data Corruption & Data Integrity in Hosting
The integrity of the data which you upload to your new hosting account will be ensured by the ZFS file system which we use on our cloud platform. Most of the hosting service providers, like our firm, use multiple HDDs to store content and considering that the drives work in a RAID, exactly the same information is synchronized between the drives all the time. If a file on a drive becomes damaged for some reason, yet, it's very likely that it will be copied on the other drives because alternative file systems don't have special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the bad copy shall be swapped with a good one from a different hard disk. Since this happens in real time, there's no possibility for any of your files to ever get damaged.
