Data corruption is the damage of information because of various hardware or software fails. After a file is damaged, it will no longer work as it should, so an app will not start or shall give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for website hosting servers as failures are much more likely to occur on bigger hard drives where substantial volumes of info are kept. When a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it is 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. A lot of the file systems which run on web servers these days often are not able to find corrupted files right away or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Web Hosting

If you host your sites in a web hosting account with our company, you won't have to worry about your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform employs the outstanding ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All the info that you upload will be saved in a RAID i.e. simultaneously on multiple SSD drives. All the file systems synchronize the files between the separate drives using this kind of a setup, but there's no real guarantee that a file won't be corrupted. This may occur during the writing process on each drive and afterwards a corrupted copy can 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 instantly and in case a corrupted file is located, it's substituted with a good copy with the correct checksum from some other drive. This way, your data will stay intact no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any probability of files getting damaged silently as the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. As we store 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 saved. If there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and considering that it happens in real time, there's no chance that a damaged copy can remain on our web hosting servers or that it can be copied to the other hard disks in the RAID. None of the other file systems employ such checks and what is more, even during a file system check after an unexpected electrical power failure, none of them can discover silently corrupted files. In comparison, ZFS will not crash after a blackout and the continual checksum monitoring makes a lenghty file system check unneeded.
