Data corruption is the damage of information caused by various hardware or software problems. After a file gets corrupted, it will no longer function accurately, so an application will not start or will give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for hosting servers as fails are very likely to happen on larger hard disks where substantial volumes of information are placed. When a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as a good one and will be duplicated on all of the drives, making the harm permanent. A huge number of the file systems that run on web servers these days often cannot find corrupted files in real time or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data which you upload to your new shared website hosting account will be guaranteed by the ZFS file system that we make use of on our cloud platform. The majority of hosting suppliers, like our firm, use multiple hard drives to keep content and because the drives work in a RAID, the same data is synchronized between the drives at all times. If a file on a drive is corrupted for some reason, yet, it is more than likely that it will be copied on the other drives because other file systems do not include special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each and every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the damaged copy shall be substituted with a good one from a different disk drive. Because this happens immediately, there is no risk for any of your files to ever get damaged.

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 employ a powerful file system called ZFS. Its key advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. As we keep all content on a number of NVMe 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. In the event that there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens right away, there's no chance that a damaged copy could remain on our servers or that it could be copied to the other hard drives 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 power failure, none of them can identify silently corrupted files. In contrast, ZFS does not crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check obsolete.
