No Data Corruption & Data Integrity in Cloud Website Hosting
We have tackled the issue of silent data corruption on all our cloud website hosting servers by using the leading-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 the files in real time by using a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and continually synchronized between them for redundancy. ZFS regularly compares the checksum of all files and when any file is detected as damaged, it's replaced quickly with a good copy from another disk. As this happens in real time, there is no risk that a damaged file may remain or may be duplicated on the other SSDs. ZFS requires lots of physical memory to perform the real-time checks and the advantage of our cloud website hosting platform is that we use multiple powerful servers working together. If you host your sites with us, your information will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any probability of files getting damaged silently because the servers where your semi-dedicated server account will be created take advantage of a powerful file system known as ZFS. Its main advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. Since we save all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. In case there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because it happens right away, there's no chance that a corrupted copy can remain on our hosting servers or that it can be duplicated to the other drives in the RAID. None of the other file systems work with such checks and furthermore, even during a file system check after a sudden power failure, none of them will identify silently corrupted files. In contrast, ZFS won't crash after a blackout and the continual checksum monitoring makes a time-consuming file system check unneeded.
