Data corruption is the unintentional change of a file or the loss of information which usually occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file can become partially or entirely corrupted, so it will no longer work as it should since its bits shall be scrambled or lost. An image file, for instance, will no longer show an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In the event that this kind of a problem occurs and it's not found by the system or by an admin, the data will be corrupted silently and when this happens on a drive that is part of a RAID array where the information is synced between different drives, the corrupted file will be copied on all the other drives and the harm will become permanent. A number of popular file systems either don't feature real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a common matter on internet hosting servers where substantial amounts of info are kept.

No Data Corruption & Data Integrity in Hosting

The integrity of the data that you upload to your new hosting account will be guaranteed by the ZFS file system which we take advantage of on our cloud platform. Most web hosting providers, 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 all of the time. In case a file on a drive becomes corrupted for whatever reason, however, it is more than likely that it will be reproduced on the other drives since alternative file systems do not offer special checks for that. Unlike them, ZFS uses 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, therefore the damaged copy shall be substituted with a good one from a different drive. Due to the fact that this happens immediately, there's no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you acquire one of our semi-dedicated hosting solutions, you won't have to worry about silent file corruption because we use ZFS - an advanced file system that keeps track of all files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between a number of NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no threat for any part of your content at any moment. In comparison, alternative file systems perform checks only after a system failure, 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 could be replicated on the rest of the drives as well and you can lose critical data. Because this isn't the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
