Data corruption is the unintended modification of a file or the loss of info that often occurs during reading or writing. The reason may be hardware or software failure, and consequently, a file can become partially or entirely corrupted, so it will no longer function as it should since its bits will be scrambled or missing. An image file, for instance, will no longer present a true image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In the event that this kind of a problem appears 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 is part of a RAID array where the data is synced between different drives, the corrupted file will be duplicated on all the other drives and the harm will become permanent. A large number of frequently used file systems either do not have real-time checks or don't have high quality ones that will detect a problem before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where large volumes of info 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 employ on our cloud platform. Most of the hosting suppliers, like our firm, use multiple hard disk drives to store content and since the drives work in a RAID, the same data is synchronized between the drives at all times. When a file on a drive gets corrupted for whatever reason, yet, it's more than likely that it will be copied on the other drives since other file systems do not feature special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every single file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, and the damaged copy will be swapped with a good one from another hard drive. Due to the fact that this happens immediately, there's no possibility for any of your files to ever be damaged.
