Data corruption is the damage of data due to various hardware or software failures. When a file is damaged, it will no longer work correctly, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, that makes it a significant problem for hosting servers as problems are much more likely to happen on larger hard disk drives where vast volumes of information are stored. In case a drive is part of a RAID and the data on it is copied on other drives for redundancy, it's more than likely that the damaged file will be treated as an ordinary one and will be copied on all the drives, making the harm permanent. A lot of the file systems which operate on web servers today often are unable to recognize corrupted files instantly or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Shared Hosting

If you host your Internet sites in a shared 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 state-of-the-art ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any data that you upload will be stored in a RAID i.e. simultaneously on a number of SSD drives. A lot of file systems synchronize the files between the separate drives using this kind of a setup, but there is no real warranty that a file will not get corrupted. This may occur at the time of the writing process on each drive and after that a bad copy can be copied on all other drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all the drives instantly and in the event that a corrupted file is identified, it is substituted with a good copy with the correct checksum from some other drive. This way, your info will remain unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you acquire one of our semi-dedicated server packages, you won't need to worry about silent data corruption as we use ZFS - an advanced file system which keeps track of all files in real time. Each time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number of SSD 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 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 time. By comparison, other file systems carry out checks after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a bad copy could be replicated on the remaining disks as well and you can lose important information. Since this is not the case with ZFS, we are able to guarantee the integrity of every single file you upload no matter what.
