Data corruption is the accidental transformation of a file or the losing of information which often occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file can become partially or fully corrupted, so it will no longer function correctly as its bits shall be scrambled or lost. An image file, for instance, will no longer display an authentic image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. If such a problem occurs and it isn't found by the system or by an admin, the data will become corrupted silently and in case this happens on a drive that's part of a RAID array where the information is synced between various different drives, the corrupted file will be reproduced on all other drives and the damage will become long term. A large number of widely used file systems either don't have real-time checks or do not have high quality ones that will detect an issue before the damage is done, so silent data corruption is a common problem on internet hosting servers where huge volumes of data are kept.
No Data Corruption & Data Integrity in Web Hosting
The integrity of the data that you upload to your new web hosting account will be guaranteed by the ZFS file system which we use on our cloud platform. The majority of web hosting providers, like our firm, use multiple hard disks to store content and because the drives work in a RAID, the exact same data is synchronized between the drives at all times. When a file on a drive gets corrupted for reasons unknown, however, it's very likely that it will be reproduced on the other drives because other file systems don't have special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each and every file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy shall be substituted with a good one from another hard disk drive. Due to the fact that this happens immediately, there's no risk for any of your files to ever be corrupted.
