No Data Corruption & Data Integrity in Shared Web Hosting
We've dealt with the issue of silent data corruption on all our shared web hosting servers by using the leading-edge Z file system, or ZFS. The latter is superior to other file systems because it is the only one on the market that checks all the files in real time by employing a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it will be stored on several SSD drives and constantly synced between them for redundancy. ZFS constantly compares the checksum of all files and when 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 duplicated on the rest of the SSDs. ZFS needs a lot of physical memory in order to perform the real-time checks and the advantage of our cloud hosting platform is that we employ multiple powerful servers working together. If you host your sites with us, your data will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you purchase one of our semi-dedicated hosting solutions, you will not need to be concerned about silent file corruption since we use ZFS - an advanced file system which checks all files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number of SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from another drive. This happens right away, so there will be no risk for any part of your content at any moment. By comparison, all the other file systems perform checks only after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a corrupted copy could be replicated on the rest of the disks as well and you may lose important data. Since this is not the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
