No Data Corruption & Data Integrity in Cloud Web Hosting
We have dealt with the problem of silent data corruption on all of our cloud web hosting servers by using the amazing Z file system, or ZFS. The latter is superior to other file systems as it is the only one out there which checks all files immediately by employing a checksum - a digital identifier that 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 analyzes the checksum of all files and in case any file is detected as corrupted, it's replaced instantly with a good copy from some other disk. As this happens in real time, there is no risk that a corrupted file may remain or may be duplicated on the rest of the SSDs. ZFS needs plenty of physical memory in order to execute the real-time checks and the advantage of our cloud hosting platform is that we take advantage of multiple powerful servers working together. If you host your sites with us, your data will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any risk of files getting corrupted silently due to the fact that the servers where your semi-dedicated server account will be created take advantage of a powerful file system called ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. As we store all content on numerous 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 stored. If there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since it happens in real time, there is no chance that a damaged copy can remain on our hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems use this type of checks and furthermore, even during a file system check following a sudden blackout, none of them will discover silently corrupted files. In contrast, ZFS does not crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check obsolete.
