No Data Corruption & Data Integrity in Shared Hosting
We've dealt with the matter of silent data corruption on all of our shared hosting servers by using the amazing Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one on the market which checks all files immediately by using a checksum - a digital identifier that's unique for each file. When you upload content to your account, it'll be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and in the event that any file is detected as corrupted, it is replaced promptly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be duplicated on the remaining SSDs. ZFS needs a lot of physical memory to perform the real-time checks and the advantage of our cloud 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 Servers
We've avoided any risk of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created use a powerful file system named ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we keep all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. When there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and because this happens right away, there is no chance that a corrupted copy could remain on our website hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems include this type of checks and what's more, even during a file system check after an unexpected blackout, none of them can detect silently corrupted files. In contrast, ZFS will not crash after a blackout and the continual checksum monitoring makes a lenghty file system check obsolete.
