Data corruption is the damage of info due to various software or hardware failures. The moment a file gets damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, that makes it a significant problem for website hosting servers as fails are very likely to happen on larger in size hard drives where large volumes of information are placed. If a drive is part of a RAID and the data on it is copied on other drives for redundancy, it's very likely that the bad file will be treated as a regular one and it'll be copied on all drives, making the damage permanent. A huge number of the file systems that operate on web servers today often are unable to detect corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

If you host your Internet sites in a cloud hosting account with our company, you do not need to worry about any of your data ever getting damaged. We can guarantee that since our cloud hosting platform employs the outstanding ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. Any kind of info that you upload will be saved in a RAID i.e. simultaneously on many SSDs. All of the file systems synchronize the files between the separate drives using such a setup, but there is no real warranty that a file won't get corrupted. This can occur at the time of the writing process on each drive and then a corrupted copy can be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all of the drives live and in the event that a corrupted file is located, it is swapped with a good copy with the correct checksum from another drive. In this way, your data will continue to be unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any possibility of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created employ a powerful file system known as ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we save all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the remaining drives and the one it has stored. When there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and because it happens right away, there's no chance that a damaged copy could remain on our web hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems employ such checks and what is more, even during a file system check after a sudden power failure, none of them will detect silently corrupted files. In contrast, ZFS doesn't crash after a power loss and the continual checksum monitoring makes a time-consuming file system check unneeded.
