No Data Corruption & Data Integrity in Shared Web Hosting
We have dealt with the issue of silent data corruption on all our shared web hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one on the market that checks all files right away by using a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and continually synced between them for redundancy. ZFS regularly compares the checksum of all files and if any file is detected as corrupted, it's replaced promptly with a good copy from another disk. As this happens in real time, there is no risk that a corrupted file may remain or may be duplicated on the remaining SSDs. ZFS needs lots of physical memory in order to execute the real-time checks and the advantage of our cloud website hosting platform is that we work with multiple powerful servers working together. In case you host your Internet sites with us, your information will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any probability of files getting corrupted silently since the servers where your semi-dedicated server account will be created take advantage of a powerful file system known as ZFS. Its key advantage over alternative 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 if the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. In case there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because this happens in real time, there's no chance that a damaged copy could remain on our servers or that it can be copied to the other hard disks in the RAID. None of the other file systems include this type 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 comparison, ZFS won't crash after a power loss and the constant checksum monitoring makes a time-consuming file system check unnecessary.
