No Data Corruption & Data Integrity in Cloud Web Hosting
We have tackled the problem of silent data corruption on our cloud web hosting servers by using the advanced Z file system, or ZFS. The latter is better than other file systems as it is the only one out there 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'll be stored on several SSD drives and constantly synced between them for redundancy. ZFS regularly examines the checksum of all files and when any file is detected as corrupted, it is replaced instantly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be duplicated on the remaining SSDs. ZFS needs plenty of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we work with multiple powerful servers working together. If you host your websites with us, your information will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any possibility of files getting damaged silently because the servers where your semi-dedicated server account will be created employ a powerful file system named ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. Since we keep all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. If there is a mismatch, the bad copy is replaced with a good one from one of the other drives and since it happens right away, there's no chance that a corrupted copy can remain on our 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 after a sudden electrical power failure, none of them will find silently corrupted files. In comparison, ZFS will not crash after a blackout and the continual checksum monitoring makes a lenghty file system check unneeded.
