No Data Corruption & Data Integrity in Cloud Hosting
We have tackled the problem of silent data corruption on all our cloud hosting servers by using the modern Z file system, or ZFS. The latter is better than other file systems since it is the only one out there which checks all the files in real time by employing a checksum - a digital identifier that's unique for every single file. When you upload content to your account, it will be stored on several SSD drives and continually synced between them for redundancy. ZFS constantly analyzes the checksum of all files and when any file is detected as damaged, 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 damaged file may remain or may be copied on the remaining SSDs. ZFS needs lots of physical memory in order to carry out the real-time checks and the advantage of our cloud website hosting platform is that we employ multiple powerful servers working together. In case you host your sites with us, your data will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you go for one of our semi-dedicated server plans, you won't need to be concerned about silent file corruption since we use ZFS - an advanced file system that monitors all of the files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between several SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens in real time, so there will be no threat for any part of your content at any time. By comparison, all the other file systems perform checks only after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a corrupted copy can be replicated on the other disks as well and you could lose important information. Since this is not the case with ZFS, we warrant the integrity of each file you upload no matter what.
