Data corruption is the damage of info because of various hardware or software failures. After a file is damaged, it will no longer function properly, so an app will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, which makes it a serious problem for website hosting servers as problems are more likely to happen on bigger hard disk drives where considerable volumes of info are kept. In case a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is likely that the bad file will be treated as an ordinary one and it will be copied on all drives, making the harm permanent. A huge number of the file systems which operate on web servers nowadays often are not able to identify corrupted files right away or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Shared Website Hosting
We warrant the integrity of the data uploaded in any shared website hosting
account that is made on our cloud platform as we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption using a unique checksum for each file. We will store your data on a number of SSD drives that function in a RAID, so exactly the same files will be present on several places at once. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged version from another drive within 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 duplicated on all drives with time, but since that can never happen on a server using ZFS, you do not have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated hosting
account will be created work with a powerful file system named ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we store all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. If there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since it happens instantly, there's no chance that a damaged copy can remain on our web hosting servers or that it can 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 following a sudden electrical power failure, none of them can detect silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the continual checksum monitoring makes a lenghty file system check obsolete.
