No Data Corruption & Data Integrity in Shared Hosting
We have tackled the matter of silent data corruption on our shared hosting servers by using the hi-tech Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one on the market that checks all the files in real time by using a checksum - a digital identifier which is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and regularly synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and in case any file is detected as damaged, it's replaced immediately with a good copy from some other disk. As this happens in real time, there is no risk that a damaged file may remain or may be duplicated on the rest of the SSDs. ZFS needs lots of physical memory to perform the real-time checks and the benefit of our cloud website hosting platform is that we take advantage of multiple powerful servers working together. In case you host your sites with us, your information will be intact 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 work with a powerful file system called ZFS. Its basic advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that's 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 corresponds to the one on the rest of the drives and the one it has saved. In case there's a mismatch, the bad copy is replaced with a good one from one of the other drives and considering that it happens in real time, there's no chance that a damaged copy can remain on our web servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems employ such checks and furthermore, even during a file system check following a sudden power failure, none of them can identify silently corrupted files. In comparison, ZFS doesn't crash after a power failure and the continual checksum monitoring makes a time-consuming file system check unneeded.
