No Data Corruption & Data Integrity in Shared Website Hosting
We have dealt with the issue of silent data corruption on all our shared website hosting servers by using the cutting-edge 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 instantly 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 frequently synchronized between them for redundancy. ZFS constantly compares the checksum of all files and if 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's no risk that a corrupted 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 take advantage of multiple very powerful servers working together. If you host your Internet sites with us, your info will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any chance of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created use a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. Since we save all content on a number of 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. When there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and because this happens instantly, there is no chance that a damaged copy could remain on our servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems employ this type of checks and what is more, even during a file system check following a sudden electrical power failure, none of them will identify silently corrupted files. In comparison, ZFS will not crash after a power loss and the constant checksum monitoring makes a time-consuming file system check obsolete.
