Data corruption is the damage of info caused by various hardware or software failures. Once a file gets corrupted, it will no longer work correctly, so an app will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, that makes it a significant problem for hosting servers as fails are much more likely to occur on larger in size hard drives where substantial volumes of information are located. When a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as an ordinary one and it'll be copied on all of the drives, making the harm permanent. A lot of the file systems which run on web servers these days often are not able to identify corrupted files instantly or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Shared Web Hosting

In case you host your Internet sites in a shared web hosting account with our company, you will not need to worry about your data ever getting corrupted. We can guarantee that as our cloud hosting platform works with the leading-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for every single file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on many NVMe drives. All file systems synchronize the files between the separate drives with this type of a setup, but there is no real warranty that a file will not be corrupted. This can happen at the time of the writing process on each drive and after that a bad copy can be copied on the rest of the drives. What is different on our platform is that ZFS examines the checksums of all files on all the drives instantly and in the event that a corrupted file is located, it is substituted with a good copy with the correct checksum from another drive. In this way, your data will remain intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you purchase one of our semi-dedicated server solutions, you will not have to worry about silent data corruption as we use ZFS - a high level file system that keeps track of 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. That file will be synchronized between several 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 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 time. In comparison, all of the other file systems perform checks after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy can be replicated on the other disks as well and you can lose critical data. Because this isn't the case with ZFS, we're able to warrant the integrity of each file you upload no matter what.
