No Data Corruption & Data Integrity in Cloud Hosting
We have tackled the matter of silent data corruption on all of our cloud hosting servers by using the amazing Z file system, or ZFS. The latter is superior to other file systems since it is the only one in existence that checks all files instantly by using a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it will be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS regularly compares the checksum of all files and in the event that any file is detected as corrupted, it is replaced immediately with a good copy from another disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the remaining SSDs. ZFS requires a lot of physical memory in order to execute the real-time checks and the benefit of our cloud hosting platform is that we employ multiple very powerful servers working together. If you host your sites with us, your data will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any risk 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 basic advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. Since we keep all content on a number of 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 stored. When there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and since it happens instantly, there's no chance that a damaged copy can remain on our servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems work with such checks and what's more, even during a file system check following a sudden power loss, none of them can detect silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check unnecessary.
