Data corruption is the damage of info caused by various software or hardware fails. When a file gets damaged, it will no longer function correctly, so an app will not start or shall give errors, a text file could be partially or entirely 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, which makes it a significant problem for web hosting servers as problems are much more likely to happen on larger hard disk drives where substantial volumes of information are placed. When a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as an ordinary one and it'll be copied on all drives, making the harm permanent. A lot of the file systems which operate on web servers these days often are unable to locate corrupted files in real time or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Hosting

If you host your Internet sites in a hosting account from our company, you won't need to worry about your data ever getting damaged. We can guarantee that as our cloud hosting platform uses the revolutionary ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. Any information that you upload will be stored in a RAID i.e. simultaneously on many different SSD drives. All the file systems synchronize the files between the different drives using such a setup, but there's no real guarantee that a file will not be corrupted. This may occur during the writing process on each drive and afterwards a bad copy may be copied on all other drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all drives live and in the event that a corrupted file is identified, it's swapped with a good copy with the correct checksum from some other drive. In this way, your information will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you purchase one of our semi-dedicated server packages, you will not need to worry about silent data corruption since we use ZFS - a high level file system which checks all files in real time. Every time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between multiple 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 in case it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no threat for any part of your content at any time. By comparison, all of the other file systems execute checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a bad copy could be replicated on the remaining drives as well and you could lose critical info. Because this is not the case with ZFS, we warrant the integrity of each file you upload no matter what.
