Data corruption is the damage of info because of various software or hardware fails. Once a file is corrupted, it will no longer function accurately, so an application will not start or shall give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, which makes it a significant problem for web hosting servers as fails are very likely to happen on bigger hard drives where considerable volumes of info are placed. When a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's very likely that the bad file will be treated as an undamaged one and will be copied on all of the drives, making the damage permanent. Lots of the file systems which run on web servers these days often are unable to find corrupted files immediately or they need time-consuming system checks through which the server is not functioning.

No Data Corruption & Data Integrity in Website Hosting

In case you host your sites in a website hosting account with our firm, you do not need to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform works with the reliable ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each and every file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on many SSD drives. All the file systems synchronize the files between the different drives using this kind of a setup, but there is no real warranty that a file will not be corrupted. This could occur at the time of the writing process on each drive and after that a bad copy may be copied on all other drives. What is different on our platform is that ZFS examines the checksums of all files on all the drives instantly and when a corrupted file is found, it's substituted with a good copy with the correct checksum from some other drive. This way, your information will stay undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any chance of files getting damaged silently since the servers where your semi-dedicated server account will be created take advantage of a powerful file system called ZFS. Its advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. Since we store all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has saved. If there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because this happens in real time, there's no chance that a damaged copy could remain on our web hosting servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems use such checks and what is more, even during a file system check after an unexpected power failure, none of them will find silently corrupted files. In comparison, ZFS will not crash after a power loss and the regular checksum monitoring makes a lenghty file system check obsolete.
