No Data Corruption & Data Integrity in Web Hosting
We've dealt with the problem of silent data corruption on our web hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one in existence that checks all the files right away by using a checksum - a digital identifier which is unique for each file. When you upload content to your account, it'll be stored on several SSD drives and continually synced between them for redundancy. ZFS constantly examines the checksum of all files and when any file is detected as damaged, it's replaced instantly 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 duplicated on the other SSDs. ZFS needs a lot of physical memory to carry out the real-time checks and the benefit of our cloud website hosting platform is that we work with multiple very powerful servers working together. In case you host your Internet sites with us, your information will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any probability of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system known as ZFS. Its main advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. Since we keep all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has saved. When 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 damaged copy could remain on our web hosting servers or that it can be duplicated to the other drives in the RAID. None of the other file systems use this type of checks and what is more, even during a file system check following a sudden power loss, none of them will discover silently corrupted files. In contrast, ZFS does not crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unneeded.
