No Data Corruption & Data Integrity in Cloud Hosting
We've tackled the matter of silent data corruption on all our cloud hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is superior to other file systems because it is the only one on the market which checks all the files immediately by using a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it will be stored on several SSD drives and constantly synchronized between them for redundancy. ZFS constantly compares the checksum of all files and in case any file is detected as corrupted, it's replaced immediately with a good copy from some other disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the other SSDs. ZFS needs plenty of physical memory in order to execute the real-time checks and the advantage of our cloud web hosting platform is that we use multiple very powerful servers working together. If you host your Internet sites with us, your information will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any probability of files getting damaged silently as the servers where your semi-dedicated hosting account will be created work with a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we save 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. When there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and because this happens instantly, there's no chance that a damaged copy can remain on our web hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems use this type of checks and in addition, even during a file system check right after an unexpected electrical 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 obsolete.
