Data corruption is the damage of data due to various software or hardware fails. The moment a file gets damaged, it will no longer work as it should, so an application will not start or will give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an admin, which makes it a serious problem for hosting servers as failures are much more likely to happen on bigger hard disk drives where considerable volumes of information are located. If a drive is part of a RAID and the data on it is copied on other drives for redundancy, it is likely that the bad file will be treated as a healthy one and it will be copied on all drives, making the harm permanent. A lot of the file systems which run on web servers these days often are unable to identify corrupted files in real time or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Website Hosting

We warrant the integrity of the information uploaded in every single website hosting account which is created on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption through a unique checksum for every single file. We shall store your information on a large number of SSD drives that operate in a RAID, so exactly the same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all files on all of the drives in real time and if the checksum of any file is different from what it has to be, the file system swaps that file with an undamaged copy from another drive from the RAID. There's no other file system that uses checksums, so it is possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created take advantage of a powerful file system called ZFS. Its main advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. As we save all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has stored. In the event that there's a mismatch, the bad copy is replaced with a good one from one of the other drives and because it happens right away, there is no chance that a corrupted copy can remain on our web servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems employ such checks and what's more, even during a file system check right after an unexpected blackout, none of them can detect silently corrupted files. In comparison, ZFS does not crash after a blackout and the constant checksum monitoring makes a lenghty file system check unnecessary.
