No Data Corruption & Data Integrity in Shared Hosting
We have tackled the issue of silent data corruption on all our shared hosting servers by using the cutting-edge Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one out there that checks all the files in real time by employing a checksum - a digital identifier which is unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and regularly synced between them for redundancy. ZFS constantly compares the checksum of all files and when any file is detected as corrupted, it is replaced right away with a good copy from some other disk. As this happens in real time, there is no risk that a corrupted file may remain or may be duplicated on the other SSDs. ZFS needs a lot of physical memory in order to execute the real-time checks and the advantage of our cloud web hosting platform is that we work with multiple very powerful servers working together. In case you host your websites with us, your information will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any chance of files getting damaged silently since the servers where your semi-dedicated hosting account will be created use a powerful file system named ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. As we store 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 stored. When there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that it happens right away, there is no chance that a damaged copy can remain on our web hosting servers or that it could be copied to the other hard drives in the RAID. None of the other file systems include such checks and what is more, even during a file system check right after a sudden blackout, none of them will discover silently corrupted files. In comparison, ZFS will not crash after a blackout and the constant checksum monitoring makes a time-consuming file system check unnecessary.
