Data corruption is the damage of info because of various software or hardware fails. Once a file gets corrupted, it will no longer function correctly, so an app will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an admin, that makes it a serious problem for hosting servers as failures are much more likely to happen on larger hard drives where vast volumes of information are stored. If a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a standard one and it will be copied on all of the drives, making the damage permanent. A huge number of the file systems which operate on web servers today often are unable to discover corrupted files right away or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Shared Website Hosting

We have resolved the issue of silent data corruption on our shared website hosting servers by using the hi-tech Z file system, or ZFS. The latter is better than other file systems because it is the only one on the market which checks all the files right away by employing a checksum - a digital identifier that is unique for each 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 compares the checksum of all files and when any file is detected as corrupted, it is replaced promptly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the remaining NVMes. ZFS needs a lot of physical memory in order to carry out the real-time checks and the advantage of our cloud website hosting platform is that we employ multiple powerful servers working together. In case you host your Internet sites with us, your data will be undamaged no matter what.
