Data corruption is the accidental transformation of a file or the losing of information which often occurs during reading or writing. The reason may be hardware or software malfunction, and as a consequence, a file can become partially or entirely corrupted, so it'll no longer work properly since its bits will be scrambled or missing. An image file, for instance, will no longer present a true image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. When such a problem appears and it is not identified by the system or by an administrator, the data will be corrupted silently and when this happens on a disk drive that's a part of a RAID array where the data is synced between different drives, the corrupted file shall be replicated on all of the other drives and the harm will become long term. A number of frequently used file systems either don't offer real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a very common issue on internet hosting servers where substantial amounts of data are kept.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data that you upload to your new shared website hosting account will be ensured by the ZFS file system that we use on our cloud platform. The majority of internet hosting service providers, including our company, use multiple HDDs to keep content and considering that the drives work in a RAID, identical data is synchronized between the drives at all times. If a file on a drive gets corrupted for some reason, however, it's very likely that it will be copied on the other drives because alternative file systems do not offer special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each and every file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, so the damaged copy will be substituted with a good one from another hard disk. Since this happens immediately, there's 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 corrupted silently because the servers where your semi-dedicated server account will be created employ a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we save all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. If there is a mismatch, the bad copy is replaced with a good one from one of the other drives and because it happens instantly, there's no chance that a corrupted copy could remain on our website hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems use such checks and what is more, even during a file system check after an unexpected electrical power failure, none of them can identify silently corrupted files. In comparison, ZFS does not crash after an electrical power failure and the continual checksum monitoring makes a time-consuming file system check unneeded.
