No Data Corruption & Data Integrity in Shared Web Hosting
We have tackled the issue of silent data corruption on our shared web hosting servers by using the hi-tech Z file system, or ZFS. The latter is more advanced than other file systems since it is the only one in existence that checks all files right away by employing a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it'll be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS constantly analyzes the checksum of all files and in the event that any file is detected as corrupted, it is replaced quickly 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 duplicated 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 website hosting platform is that we take advantage of multiple powerful servers working together. If you host your websites with us, your info will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you obtain one of our semi-dedicated hosting solutions, 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. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized 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 in case it detects a damaged copy, it replaces it with a healthy one from another drive. This happens immediately, so there will be no danger for any part of your content at any moment. By comparison, other file systems perform checks after a system malfunction, but since they don't use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the rest of the drives as well and you can lose important data. Because this is not the case with ZFS, we are able to warrant the integrity of every single file you upload no matter what.
