Data corruption is the accidental modification of a file or the loss of information which often occurs during reading or writing. The reason could be hardware or software malfunction, and for that reason, a file can become partially or fully corrupted, so it will no longer function as it should since its bits will be scrambled or missing. An image file, for example, will no longer display an authentic image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. When such a problem appears and it's not recognized by the system or by an admin, the data will become corrupted silently and if this happens on a drive that's a part of a RAID array where the info is synced between different drives, the corrupted file shall be replicated on all of the other drives and the harm will be permanent. A number of frequently used file systems either don't have real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a common problem on internet hosting servers where substantial volumes of data are kept.

No Data Corruption & Data Integrity in Web Hosting

The integrity of the data which you upload to your new web hosting account will be ensured by the ZFS file system that we use on our cloud platform. The majority of internet hosting providers, like our company, use multiple hard drives to keep content and because the drives work in a RAID, exactly the same info is synchronized between the drives at all times. When a file on a drive is damaged for reasons unknown, yet, it is very likely that it will be reproduced on the other drives because other file systems don't have special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each and every file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the bad copy will be swapped with a good one from a different hard drive. As this happens immediately, 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 risk of files getting corrupted silently as the servers where your semi-dedicated server account will be created work with a powerful file system known as ZFS. Its key advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. As we store all content on multiple NVMe drives, ZFS checks whether the fingerprint of a file on one drive matches 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 because it happens instantly, there's no chance that a damaged copy can remain on our hosting servers or that it could be copied to the other drives in the RAID. None of the other file systems employ such checks and what's more, even during a file system check after an unexpected power failure, none of them will discover silently corrupted files. In contrast, ZFS will not crash after a blackout and the constant checksum monitoring makes a lenghty file system check obsolete.
