No Data Corruption & Data Integrity in Web Hosting
We've dealt with the problem of silent data corruption on all our 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 the files right away by using 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 synchronized between them for redundancy. ZFS constantly compares the checksum of all files and if any file is detected as damaged, it is replaced promptly with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be copied on the rest of the SSDs. ZFS requires plenty of physical memory in order to perform the real-time checks and the benefit of our cloud hosting platform is that we take advantage of multiple very powerful servers working together. If you host your websites with us, your info will be intact no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you get one of our semi-dedicated hosting plans, you won't have to worry about silent file corruption since we use ZFS - a high level file system which monitors all 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. That 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 copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done immediately, so there will be no risk for any part of your content at any time. In comparison, all the other file systems perform checks only after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy can be replicated on the rest of the drives as well and you can lose critical information. As this isn't the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
