Data corruption is the damage of information because of various software or hardware failures. The moment a file gets damaged, it will no longer function as it should, so an application will not start or shall give errors, a text file will be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as problems are much more likely to occur on larger in size hard disk drives where considerable volumes of information are placed. When a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as a standard one and it'll be copied on all of the drives, making the harm permanent. A lot of the file systems which run on web servers these days often are not able to detect corrupted files in real time or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Shared Web Hosting

We warrant the integrity of the data uploaded in each shared web hosting account that is created on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption through a unique checksum for every single file. We shall store your information on multiple NVMe drives which work in a RAID, so the same files will be available on several places concurrently. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with an undamaged copy from a different drive in the RAID. There's no other file system which uses checksums, so it is possible for data to be silently corrupted and the bad file to be replicated on all drives with time, but since this can never happen on a server using ZFS, you will not have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created work with a powerful file system called ZFS. Its advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we store all content on a number of NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. In the event that there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because this happens right away, there is no chance that a corrupted copy can remain on our hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems employ this type of checks and furthermore, even during a file system check right after a sudden power failure, none of them can identify silently corrupted files. In comparison, ZFS does not crash after a blackout and the constant checksum monitoring makes a time-consuming file system check unnecessary.
