No Data Corruption & Data Integrity in Shared Web Hosting
We have tackled the problem of silent data corruption on our shared web hosting servers by using the advanced Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one in existence that checks all of the files right away by using a checksum - a digital identifier that's unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and constantly synced between them for redundancy. ZFS regularly examines the checksum of all files and in the event that any file is detected as corrupted, it's replaced promptly with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be duplicated on the other SSDs. ZFS requires lots of physical memory in order to carry out the real-time checks and the benefit of our cloud hosting platform is that we employ multiple very powerful servers working together. In case you host your Internet sites with us, your info will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you get one of our semi-dedicated hosting plans, you will not need to be concerned about silent data corruption since we use ZFS - a high level file system that keeps track of all of the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced 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 of the 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 threat for any part of your content at any time. In comparison, alternative file systems execute checks after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a bad copy could be replicated on the rest of the drives as well and you may lose crucial data. Because this is not the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
