Data corruption is the damage of info caused by various hardware or software failures. After a file gets corrupted, it will no longer function properly, so an app will not start or shall give errors, a text file can be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, that makes it a serious problem for web hosting servers as fails are more likely to occur on bigger hard disk drives where large volumes of information are kept. When a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's likely that the damaged file will be treated as a healthy one and will be duplicated on all the drives, making the damage permanent. Lots of the file systems which operate on web servers these days often are not able to discover corrupted files instantly or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Website Hosting

In case you host your Internet sites in a website hosting account from our firm, you won't have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform uses the reliable ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. All the information that you upload will be kept in a RAID i.e. simultaneously on numerous SSD drives. All 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 could happen throughout the writing process on each drive and then a corrupted copy can be copied on the other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all the drives right away and when a corrupted file is discovered, it's swapped with a good copy with the correct checksum from some other drive. This way, your info will stay unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. As we store all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has stored. In the event that there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and considering that this happens instantly, there is no chance that a corrupted copy could remain on our website hosting servers or that it can be copied 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 following an unexpected blackout, none of them will discover silently corrupted files. In comparison, ZFS doesn't crash after a blackout and the constant checksum monitoring makes a lenghty file system check unnecessary.
