Data corruption is the damage of data caused by various hardware or software problems. When a file gets corrupted, it will no longer function accurately, so an application will not start or shall give errors, a text file will be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for hosting servers as failures are very likely to happen on larger hard drives where vast volumes of info are kept. When a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a good one and it'll be duplicated on all of the drives, making the damage permanent. A lot of the file systems which operate on web servers today often cannot identify corrupted files instantly or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Hosting

We guarantee the integrity of the data uploaded in any hosting account which is made on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption through a unique checksum for every single file. We'll store your info on multiple SSD drives which operate in a RAID, so exactly 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 case the checksum of any file differs from what it has to be, the file system replaces that file with a healthy copy from another drive in the RAID. There's no other file system that uses checksums, so it's possible for data to become silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any probability of files getting corrupted silently as the servers where your semi-dedicated server account will be created work with a powerful file system named ZFS. Its key advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. Since we keep all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. In case there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that this happens in real time, there's no chance that a damaged copy could remain on our website hosting servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems use this type of checks and what's more, even during a file system check right after a sudden electrical power failure, none of them will find silently corrupted files. In comparison, ZFS will not crash after a blackout and the continual checksum monitoring makes a lenghty file system check unneeded.
