Data corruption is the damage of data caused by various software or hardware problems. After a file is damaged, it will no longer work correctly, so an application will not start or will give errors, a text file can be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an administrator, that makes it a serious problem for web hosting servers as problems are more likely to occur on bigger hard drives where vast volumes of information are placed. If a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a standard one and will be duplicated on all drives, making the damage permanent. Lots of the file systems which run on web servers nowadays often are not able to locate corrupted files right away or they need time-consuming system checks during which the server is not working.
No Data Corruption & Data Integrity in Hosting
We warrant the integrity of the information uploaded in each and every hosting account that is created on our cloud platform because we employ the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption via a unique checksum for each file. We shall store your info on multiple NVMe drives which work in a RAID, so the same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file differs from what it has to be, the file system replaces that file with a healthy copy from some other drive in the RAID. There's no other file system which uses checksums, so it's possible for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since this can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any risk of files getting corrupted silently because the servers where your semi-dedicated server account will be created work with a powerful file system known as ZFS. Its key advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. Since we save all content on a number of NVMe drives, ZFS checks whether 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 is a mismatch, the bad copy is replaced with a good one from one of the other drives and because it happens instantly, there's no chance that a damaged copy can remain on our hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems work with such checks and what is more, even during a file system check after an unexpected power failure, none of them will detect silently corrupted files. In contrast, ZFS won't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
