Data corruption is the damage of data due to various hardware or software problems. When a file gets corrupted, it will no longer work properly, so an application will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open and 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 website hosting servers as failures are more likely to occur on larger hard drives where considerable volumes of information are located. If a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is very likely that the damaged file will be treated as a regular one and it will be duplicated on all of the drives, making the harm permanent. Lots of the file systems which operate on web servers today often are unable to detect corrupted files instantly or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Shared Hosting

We warrant the integrity of the information uploaded in every single shared hosting account that is generated on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption using a unique checksum for every single file. We shall store your data on multiple NVMe drives that function in a RAID, so the exact same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all 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 a different drive within the RAID. There's no other file system which uses checksums, so it is easy for data to be silently damaged and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any chance of files getting corrupted silently since the servers where your semi-dedicated server account will be created work with a powerful file system known as ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for every single 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 matches the one on the rest of the drives and the one it has saved. In the event that there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and considering that this happens in real time, there's no chance that a corrupted copy can remain on our servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems use this kind of checks and what's more, even during a file system check after an unexpected blackout, none of them will find silently corrupted files. In contrast, ZFS doesn't crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check unneeded.
