No Data Corruption & Data Integrity in Cloud Hosting
We have tackled the issue of silent data corruption on all of our cloud hosting servers by using the advanced Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one in existence which checks all files right away by employing a checksum - a digital identifier that's unique for each file. When you upload content to your account, it will be stored on several SSD drives and continually synchronized between them for redundancy. ZFS constantly examines the checksum of all files and if any file is detected as damaged, it is replaced right away with a good copy from another disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the rest of the SSDs. ZFS needs a lot of physical memory in order to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple very powerful servers working together. If you host your Internet sites with us, your data will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any risk of files getting damaged silently since the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system called ZFS. Its basic 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 store all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has saved. In the event that there is a mismatch, the corrupted copy is replaced with a healthy 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 web servers or that it could be copied 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 right after a sudden power loss, none of them can find silently corrupted files. In contrast, ZFS does not crash after an electrical power failure and the regular checksum monitoring makes a lenghty file system check unneeded.
