Data corruption is the damage of information because of various software or hardware fails. Once a file gets damaged, it will no longer function properly, so an app will not start or shall give errors, a text file can be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, that makes it a significant problem for hosting servers as fails are very likely to happen on bigger hard drives where large volumes of info are kept. In case a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's very likely that the damaged file will be treated as a healthy one and it'll be duplicated on all the drives, making the harm permanent. A lot of the file systems that operate on web servers nowadays often cannot identify corrupted files instantly or they need time-consuming system checks through 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 will be ensured by the ZFS file system which we use on our cloud platform. Most of the internet hosting suppliers, including our company, use multiple hard drives to store content and because the drives work in a RAID, the same data is synchronized between the drives all the time. In case a file on a drive becomes corrupted for whatever reason, however, it is more than likely that it will be duplicated on the other drives as alternative file systems do not have special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for 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 damaged copy shall be substituted with a good one from another drive. Because this happens immediately, there is no risk 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 have to worry about silent data corruption as we use ZFS - a high level file system which keeps track of all the files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a couple of NVMe drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done immediately, so there will be no danger for any part of your content at any moment. In contrast, all of the other file systems perform checks after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy can be replicated on the remaining drives as well and you could lose important information. Because this is not the case with ZFS, we guarantee the integrity of each file you upload no matter what.
