Data corruption is the damage of info because of various software or hardware fails. The moment a file gets damaged, it will no longer work as it should, so an application will not start or shall give errors, a text file shall 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 harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for web hosting servers as fails are more likely to occur on larger hard disks where considerable volumes of info are placed. If a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as an ordinary one and it'll be duplicated on all of the drives, making the harm permanent. Lots of the file systems that run on web servers today often are not able to discover 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 Shared Hosting

We guarantee the integrity of the data uploaded in every single shared hosting account that is made on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption via a unique checksum for each file. We'll store your info on a number of SSD drives that operate in a RAID, so the 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 case the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged version from a different drive in the RAID. There's no other file system which uses checksums, so it is easy for data to get silently corrupted and the bad file to be duplicated on all drives with time, but since this 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 Servers

We have avoided any chance of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created use a powerful file system named ZFS. Its advantage over alternative 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 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. When there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and because it happens right away, there is no chance that a corrupted copy could remain on our servers or that it can be duplicated to the other drives in the RAID. None of the other file systems employ this kind of checks and what's more, even during a file system check following a sudden power failure, none of them can identify silently corrupted files. In contrast, ZFS doesn't crash after a power loss and the continual checksum monitoring makes a lenghty file system check obsolete.
