Data corruption is the unintentional modification of a file or the losing of info that usually occurs during reading or writing. The reason may be hardware or software malfunction, and because of this, a file could become partially or completely corrupted, so it will no longer work correctly as its bits shall be scrambled or missing. An image file, for instance, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When such a problem occurs and it isn't noticed by the system or by an admin, the data will be corrupted silently and if this happens on a disk drive which is a part of a RAID array where the information is synchronized between different drives, the corrupted file shall be copied on all the other drives and the harm will be long term. A large number of widely used file systems either don't feature real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where large amounts of information are kept.

No Data Corruption & Data Integrity in Website Hosting

The integrity of the data that you upload to your new website hosting account will be ensured by the ZFS file system which we work with on our cloud platform. Most web hosting suppliers, including our company, use multiple hard disk drives to keep content and because the drives work in a RAID, identical information is synchronized between the drives at all times. When a file on a drive gets corrupted for reasons unknown, however, it's very likely that it will be copied on the other drives because other file systems do not include special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the bad copy will be replaced with a good one from a different hard drive. Because this happens instantly, there's no possibility for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any probability of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. Since we save all content on numerous NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has saved. In the event that there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and because it happens right away, there is no chance that a corrupted copy can remain on our servers or that it can be duplicated to the other drives in the RAID. None of the other file systems work with this kind of checks and what is more, even during a file system check right after an unexpected blackout, none of them will discover silently corrupted files. In comparison, ZFS won't crash after a power loss and the regular checksum monitoring makes a lenghty file system check unneeded.
