No Data Corruption & Data Integrity in Cloud Hosting
We've dealt with the problem of silent data corruption on our cloud hosting servers by using the advanced Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one out there which checks all 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 regularly synchronized between them for redundancy. ZFS constantly examines the checksum of all files and in case any file is detected as corrupted, it is replaced promptly with a good copy from some other disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the remaining SSDs. ZFS requires lots of physical memory in order to carry out the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple powerful servers working together. If you host your sites with us, your info will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any risk of files getting damaged silently because the servers where your semi-dedicated server account will be created work with a powerful file system called ZFS. Its main advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. Since we save all content on multiple 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 stored. If there's a mismatch, the bad copy is replaced with a good one from one of the other drives and since it happens right away, there is no chance that a corrupted copy can remain on our servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems use this kind of checks and what's more, even during a file system check after an unexpected power failure, none of them will detect silently corrupted files. In contrast, ZFS won't crash after a power failure and the continual checksum monitoring makes a time-consuming file system check obsolete.
