No Data Corruption & Data Integrity in Shared Web Hosting
We've dealt with the matter of silent data corruption on our shared web hosting servers by using the leading-edge Z file system, or ZFS. The latter is better than other file systems since it is the only one out there that checks all files in real time 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 SSD drives and constantly synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and when any file is detected as damaged, it's replaced immediately with a good copy from another disk. As this happens in real time, there's no risk that a bad file may remain or may be copied on the rest of the SSDs. ZFS requires lots of physical memory in order to perform the real-time checks and the advantage of our cloud website hosting platform is that we take advantage of multiple very powerful servers working together. If you host your sites with us, your data will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any probability of files getting damaged silently due to the fact that the servers where your semi-dedicated hosting account will be created use a powerful file system known as ZFS. Its advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we save all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has saved. If there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because it happens instantly, there is no chance that a corrupted copy could remain on our web hosting servers or that it can be copied to the other hard disks in the RAID. None of the other file systems use this kind of checks and furthermore, even during a file system check after a sudden electrical power failure, none of them will find silently corrupted files. In comparison, ZFS won't crash after a power loss and the constant checksum monitoring makes a time-consuming file system check unneeded.
