No Data Corruption & Data Integrity in Hosting
We have tackled the problem of silent data corruption on all of our hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is superior to 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 each and every file. When you upload content to your account, it'll be stored on several SSD drives and continually synchronized between them for redundancy. ZFS regularly compares the checksum of all files and in the event that any file is detected as corrupted, it is replaced right away with a good copy from some other disk. As this happens in real time, there is no risk that a damaged file may remain or may be copied on the remaining SSDs. ZFS requires lots of physical memory to carry out the real-time checks and the advantage of our cloud web hosting platform is that we employ multiple very powerful servers working together. If you host your Internet sites with us, your data will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any probability of files getting corrupted silently since the servers where your semi-dedicated hosting account will be created employ a powerful file system named ZFS. Its advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. As 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 remaining drives and the one it has saved. In the event that there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because it happens in real time, there is no chance that a damaged copy can remain on our web servers or that it can be copied to the other hard drives in the RAID. None of the other file systems employ this kind of checks and what is more, even during a file system check following an unexpected power failure, none of them will identify silently corrupted files. In comparison, ZFS does not crash after a power loss and the constant checksum monitoring makes a lenghty file system check unnecessary.
