Data corruption is the unintentional change of a file or the loss of information that usually occurs during reading or writing. The reason could be hardware or software failure, and due to this fact, a file may become partially or fully corrupted, so it'll no longer function as it should since its bits will be scrambled or missing. An image file, for instance, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. If such a problem appears and it is not noticed by the system or by an admin, the data will be corrupted silently and if this happens on a drive which is a part of a RAID array where the info is synchronized between different drives, the corrupted file shall be replicated on all other drives and the harm will become long term. A large number of frequently used file systems either do not feature real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a very common problem on hosting servers where huge amounts of data are kept.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data which you upload to your new shared website hosting account shall be ensured by the ZFS file system which we use on our cloud platform. Most hosting suppliers, including our firm, use multiple hard drives to keep content and because the drives work in a RAID, identical information is synchronized between the drives at all times. If a file on a drive gets corrupted for some reason, yet, it is likely that it will be copied on the other drives since alternative file systems don't include special checks for that. 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 will not match what ZFS has as a record for it, which means that the bad copy shall be substituted with a good one from another disk drive. Due to the fact that this happens instantly, there is no possibility for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created take advantage of a powerful file system named ZFS. Its advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we keep all content on multiple NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In case there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and since it happens in real time, there is no chance that a corrupted copy can remain on our servers or that it can be copied to the other hard drives in the RAID. None of the other file systems employ such checks and what's more, even during a file system check right after a sudden electrical power failure, none of them can discover silently corrupted files. In contrast, ZFS doesn't crash after a blackout and the continual checksum monitoring makes a time-consuming file system check unneeded.
