No Data Corruption & Data Integrity in Shared Hosting
We have tackled the issue of silent data corruption on all of our shared hosting servers by using the hi-tech Z file system, or ZFS. The latter is better than other file systems since it is the only one in existence which checks all of the files right away by using a checksum - a digital identifier which is unique for every single file. When you upload content to your account, it will be stored on several NVMe drives and continually synced between them for redundancy. ZFS constantly analyzes the checksum of all files and when any file is detected as corrupted, it is replaced instantly with a good copy from some other disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the remaining NVMes. ZFS needs lots of physical memory in order to execute the real-time checks and the benefit of our cloud web hosting platform is that we work with multiple 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 Servers
We've avoided any chance of files getting corrupted silently as the servers where your semi-dedicated server account will be created use a powerful file system called ZFS. Its main advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. As we save all content on numerous 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 saved. If there is a mismatch, the bad copy is replaced with a good one from one of the other drives and since this happens right away, there is no chance that a corrupted 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 work with this type of checks and what is more, even during a file system check right after a sudden blackout, none of them will find silently corrupted files. In comparison, ZFS does not crash after a blackout and the constant checksum monitoring makes a lenghty file system check unnecessary.
