Data corruption is the damage of data caused by various software or hardware failures. Once a file gets damaged, it will no longer work correctly, so an application will not start or shall give errors, a text file will be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, that makes it a significant problem for website hosting servers as fails are much more likely to occur on larger in size hard drives where large volumes of information are kept. If a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's more than likely that the damaged file will be treated as an undamaged one and it'll be duplicated on all drives, making the harm permanent. Lots of the file systems that run on web servers these days often cannot identify corrupted files right away or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the information uploaded in every single cloud hosting account that is generated on our cloud platform as 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'll store your information on multiple NVMe drives that function in a RAID, so identical files will exist on several places concurrently. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in case the checksum of any file is different from what it has to be, the file system swaps that file with a healthy copy from some other drive from 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 running ZFS, you will not have to worry about the integrity of your info.

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 take advantage of a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we store all content on numerous NVMe drives, ZFS checks whether 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 considering that this happens instantly, there's no chance that a corrupted copy could remain on our hosting servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems use this type of checks and in addition, even during a file system check following an unexpected electrical power failure, none of them will discover silently corrupted files. In contrast, ZFS does not crash after a power failure and the continual checksum monitoring makes a lenghty file system check obsolete.
