Data corruption is the damage of data due to various hardware or software problems. The moment a file gets corrupted, it will no longer function as it should, so an application will not start or will give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an administrator, that makes it a significant problem for hosting servers as fails are more likely to occur on larger hard disks where substantial volumes of information are stored. If a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a good one and it'll be copied on all the drives, making the damage permanent. Lots of the file systems that run on web servers today often are not able to locate corrupted files immediately or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Hosting

The integrity of the data that you upload to your new hosting account shall be guaranteed by the ZFS file system that we use on our cloud platform. The vast majority of hosting suppliers, including our company, use multiple hard disk drives to keep content and because the drives work in a RAID, exactly the same information is synchronized between the drives all of the time. In case a file on a drive becomes corrupted for some reason, yet, it's very likely that it will be copied on the other drives as alternative file systems do not have special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the bad copy shall be substituted with a good one from a different drive. Due to the fact that this happens instantly, there is no risk for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you buy one of our semi-dedicated server packages, you won't have to be concerned about silent file corruption as we use ZFS - an advanced file system that monitors all of the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between several NVMe drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no danger for any part of your content at any moment. In comparison, other file systems perform checks only after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy can be replicated on the other drives as well and you may lose critical information. Since this is not the case with ZFS, we can guarantee the integrity of every single file you upload no matter what.
