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 fail, and due to this fact, a file could become partially or completely corrupted, so it will no longer work correctly since its bits shall be scrambled or lacking. An image file, for instance, will no longer display 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, etc. In the event that this kind of a problem occurs and it is not found by the system or by an administrator, the data will become corrupted silently and when this happens on a drive that is part of a RAID array where the data is synchronized between different drives, the corrupted file shall be copied on all other drives and the harm will become permanent. A large number of frequently used file systems either don't feature real-time checks or don't have high quality ones that will detect a problem before the damage is done, so silent data corruption is a common problem on web hosting servers where substantial amounts of info are stored.

No Data Corruption & Data Integrity in Shared Web Hosting

The integrity of the data that you upload to your new shared web hosting account shall be ensured by the ZFS file system which we use on our cloud platform. Most internet hosting suppliers, like our firm, use multiple hard disk drives to store content and because the drives work in a RAID, the exact same data is synchronized between the drives all the time. When a file on a drive becomes corrupted for some reason, yet, it is very likely that it will be copied on the other drives because other file systems do not include special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for every file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the damaged copy shall be replaced with a good one from another hard disk. As this happens in real time, there is no possibility for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you buy one of our semi-dedicated server packages, you will not need to worry about silent file corruption since we use ZFS - an advanced file system which checks all of the files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between a couple of NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no threat for any part of your content at any moment. By comparison, all of the other file systems carry out checks only after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy can be replicated on the other drives as well and you can lose crucial information. Since this is not the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
