No Data Corruption & Data Integrity in Shared Web Hosting
We have resolved the matter of silent data corruption on all of our shared web hosting servers by using the hi-tech Z file system, or ZFS. The latter is better than other file systems since it is the only one in existence that checks all of the files immediately by using a checksum - a digital identifier that 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 constantly examines the checksum of all files and in the event that any file is detected as damaged, it is replaced promptly with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be copied on the other SSDs. ZFS needs a lot of physical memory to execute the real-time checks and the advantage of our cloud website hosting platform is that we take advantage of multiple very powerful servers working together. In case you host your Internet sites with us, your info will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any risk of files getting damaged silently because the servers where your semi-dedicated hosting account will be created employ a powerful file system called ZFS. Its advantage over 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 if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. If there's a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and since it happens instantly, there's no chance that a corrupted copy can remain on our hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems include this type of checks and what is more, even during a file system check following a sudden power loss, none of them will identify 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 unnecessary.
