Data corruption is the damage of info due to various hardware or software fails. When a file is damaged, it will no longer function correctly, so an application will not start or will give errors, a text file can be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, that makes it a serious problem for hosting servers as problems are very likely to happen on larger hard disk drives where significant volumes of information are placed. If a drive is a 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 a healthy one and it will be copied on all the drives, making the damage permanent. A lot of the file systems that run on web servers nowadays often are unable to find corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Web Hosting

We have resolved the problem of silent data corruption on all of our shared web hosting servers by using the cutting-edge Z file system, or ZFS. The latter is superior to other file systems since it is the only one on the market which checks all files in real time by using a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it'll be stored on several NVMe drives and continually synced between them for redundancy. ZFS constantly analyzes the checksum of all files and in case any file is detected as damaged, it's replaced quickly with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be copied on the remaining NVMes. ZFS requires lots of physical memory to perform the real-time checks and the benefit of our cloud hosting platform is that we use multiple very powerful servers working together. If you host your Internet sites with us, your information will be intact no matter what.

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 known as ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. Since 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 other drives and the one it has saved. When there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and considering that this happens in real time, there is no chance that a corrupted copy could remain on our hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems include this kind of checks and what's more, even during a file system check right after a sudden blackout, none of them can detect silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the constant checksum monitoring makes a time-consuming file system check unnecessary.
