No Data Corruption & Data Integrity in Cloud Web Hosting
We've resolved the matter of silent data corruption on our cloud web hosting servers by using the modern Z file system, or ZFS. The latter is better than other file systems since it is the only one on the market which checks all files instantly by employing a checksum - a digital identifier that is unique for each file. When you upload content to your account, it'll be stored on several SSD drives and regularly synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and in the event that any file is detected as damaged, it's replaced quickly 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 copied on the remaining SSDs. ZFS needs plenty of physical memory in order to carry out the real-time checks and the advantage of our cloud web hosting platform is that we use multiple powerful servers working together. If you host your sites with us, your info will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any probability of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created use a powerful file system known as ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. As 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 rest of the drives and the one it has saved. If there's a mismatch, the bad 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 could remain on our web servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems include such checks and furthermore, even during a file system check after a sudden power failure, none of them will identify silently corrupted files. In comparison, ZFS won't crash after a power failure and the regular checksum monitoring makes a time-consuming file system check unneeded.
