No Data Corruption & Data Integrity in Shared Hosting
We've resolved the issue of silent data corruption on our shared hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one on the market that checks all files in real time by using a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and regularly synchronized between them for redundancy. ZFS regularly compares the checksum of all files and in case any file is detected as corrupted, it's replaced instantly with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be copied on the remaining SSDs. ZFS needs a lot of physical memory to perform the real-time checks and the benefit of our cloud hosting platform is that we work with multiple very powerful servers working together. In case you host your websites with us, your data will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any probability of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created work with a powerful file system called 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. As we keep all content on multiple SSD drives, ZFS checks whether 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's a mismatch, the damaged copy is replaced with a good one from one of the other drives and since it 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 drives in the RAID. None of the other file systems work with this kind of checks and furthermore, even during a file system check following a sudden power loss, none of them will identify silently corrupted files. In contrast, ZFS does not crash after a power loss and the constant checksum monitoring makes a lenghty file system check unneeded.
