No Data Corruption & Data Integrity in Cloud Web Hosting
We have dealt with the matter of silent data corruption on our cloud web hosting servers by using the advanced Z file system, or ZFS. The latter is better than other file systems since it is the only one out there that checks all of the files right away by using a checksum - a digital identifier which is unique for each and every 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 examines the checksum of all files and if any file is detected as damaged, it's replaced promptly with a good copy from some other disk. As this happens in real time, there's no risk that a corrupted file may remain or may be copied on the remaining SSDs. ZFS requires a lot of physical memory in order to execute the real-time checks and the benefit of our cloud web hosting platform is that we work with multiple very powerful servers working together. If you host your Internet sites with us, your information will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any chance of files getting damaged silently because the servers where your semi-dedicated hosting account will be created take advantage of a powerful file system known as 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 store all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. In case there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and considering that this happens right away, there's no chance that a corrupted copy could remain on our web servers or that it can be copied to the other hard disks in the RAID. None of the other file systems work with this kind of checks and in addition, even during a file system check following an unexpected power failure, none of them can find silently corrupted files. In contrast, ZFS doesn't crash after a power failure and the continual checksum monitoring makes a time-consuming file system check unnecessary.
