Data corruption is the unintended modification of a file or the loss of info which usually occurs during reading or writing. The reason could be hardware or software fail, and as a result, a file can become partially or fully corrupted, so it'll no longer work properly because its bits shall be scrambled or missing. An image file, for instance, will no longer present a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In the event that this kind of an issue appears and it is not recognized by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive that is part of a RAID array where the information is synced between different drives, the corrupted file will be replicated on all other drives and the harm will be long term. Numerous popular file systems either don't have 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 issue on web hosting servers where huge amounts of information are stored.

No Data Corruption & Data Integrity in Cloud Website Hosting

The integrity of the data that you upload to your new cloud website hosting account shall be guaranteed by the ZFS file system that we work with on our cloud platform. The majority of hosting suppliers, like our company, use multiple hard disk drives to keep content and since the drives work in a RAID, identical info is synchronized between the drives at all times. If a file on a drive gets damaged for reasons unknown, however, it is more than likely that it will be duplicated on the other drives because other file systems do not offer special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the damaged copy will be substituted with a good one from a different disk drive. Since this happens instantly, there's no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any possibility of files getting damaged silently since the servers where your semi-dedicated server account will be created take advantage of a powerful file system known as ZFS. Its main advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we store all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. When there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and since this happens in real time, there's no chance that a corrupted copy can remain on our hosting servers or that it can be duplicated to the other drives in the RAID. None of the other file systems use such checks and what's more, even during a file system check following a sudden electrical power failure, none of them will discover silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check obsolete.
