Data corruption is the damage of info because of various software or hardware problems. After a file is corrupted, it will no longer function as it should, so an app will not start or will give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, which makes it a significant problem for web hosting servers as problems are more likely to occur on larger hard disk drives where substantial volumes of info are located. When a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it is more than likely that the damaged file will be treated as a standard one and it'll be copied on all the drives, making the harm permanent. Lots of the file systems which run on web servers nowadays often are unable to detect corrupted files in real time or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Hosting

We guarantee the integrity of the info uploaded in every single hosting account which is made on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption through a unique checksum for each and every file. We will store your info on multiple SSD drives that work in a RAID, so the exact same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system swaps that file with an undamaged version from some other drive within the RAID. There's no other file system which uses checksums, so it's possible for data to become silently damaged and the bad file to be duplicated on all drives with time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any risk of files getting damaged silently because the servers where your semi-dedicated hosting account will be created work with a powerful file system called ZFS. Its basic 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 save all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has stored. If there is a mismatch, the bad copy is replaced with a good one from one of the other drives and since this happens in real time, there is no chance that a corrupted copy could remain on our servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems include this kind of checks and what is more, even during a file system check right after a sudden blackout, none of them will find silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check unnecessary.
