Data corruption is the damage of information because of various hardware or software failures. After a file gets corrupted, it will no longer work properly, so an app will not start or shall give errors, a text file shall be partially or fully unreadable, an archive file will be impossible to open and 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 web hosting servers as fails are much more likely to happen on larger hard drives where considerable volumes of information are kept. If a drive is part of a RAID and the information on it is copied on other drives for redundancy, it's likely that the bad file will be treated as a standard one and will be copied on all drives, making the harm permanent. A lot of the file systems which operate on web servers today often are not able to detect corrupted files right away or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Hosting

In case you host your websites in a hosting account with our company, you do not need to worry about any of your data ever getting damaged. We can ensure that as our cloud hosting platform employs the state-of-the-art ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. Any data that you upload will be saved in a RAID i.e. simultaneously on a large number of SSD drives. A lot of file systems synchronize the files between the different drives with this type of a setup, but there is no real warranty that a file will not be corrupted. This may occur during the writing process on each drive and afterwards a damaged copy can be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all the drives right away and in case a corrupted file is located, it's swapped with a good copy with the correct checksum from another drive. This way, your info will continue to be unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you buy one of our semi-dedicated hosting plans, you won't need to be concerned about silent data corruption since we use ZFS - an advanced file system that monitors all 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 synced between a number of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and when it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens right away, so there will be no danger for any part of your content at any time. By comparison, other file systems execute checks only after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a bad copy may be replicated on the other disks as well and you can lose crucial information. Because this isn't the case with ZFS, we're able to warrant the integrity of each file you upload no matter what.
