Data corruption is the accidental change of a file or the losing of information that often occurs during reading or writing. The reason may be hardware or software fail, and due to this fact, a file may become partially or entirely corrupted, so it'll no longer work correctly since its bits shall be scrambled or missing. An image file, for instance, will no longer display a real image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. If such an issue appears and it is not recognized by the system or by an administrator, the data will become corrupted silently and if this happens on a disk drive which is a part of a RAID array where the information is synchronized between various drives, the corrupted file will be copied on all the other drives and the damage will be permanent. A number of widely used file systems either do not feature real-time checks or don't have high quality ones that will detect an issue before the damage is done, so silent data corruption is a common problem on web hosting servers where substantial volumes of information are kept.
No Data Corruption & Data Integrity in Web Hosting
The integrity of the data which you upload to your new web hosting account shall be ensured by the ZFS file system which we use on our cloud platform. Most of the web hosting providers, including our firm, use multiple hard disks to store content and since the drives work in a RAID, the same information is synchronized between the drives at all times. If a file on a drive gets corrupted for some reason, yet, it's very likely that it will be duplicated on the other drives since other file systems do not feature special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the damaged copy will be swapped with a good one from a different hard disk drive. Due to the fact that this happens in real time, there's no possibility for any of your files to ever get damaged.
