No Data Corruption & Data Integrity in Cloud Web Hosting
We have tackled the issue of silent data corruption on all our cloud web hosting servers by using the modern Z file system, or ZFS. The latter is superior to other file systems because it is the only one in existence that checks all files instantly by employing a checksum - a digital identifier that's unique for each file. When you upload content to your account, it'll be stored on several SSD drives and regularly synced between them for redundancy. ZFS regularly analyzes the checksum of all files and in case any file is detected as corrupted, it's replaced instantly with a good copy from another disk. As this happens in real time, there is no risk that a bad file may remain or may be duplicated on the rest of the SSDs. ZFS requires lots of physical memory in order to carry out the real-time checks and the advantage of our cloud web hosting platform is that we employ multiple powerful servers working together. In case you host your Internet sites with us, your data will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you go for one of our semi-dedicated hosting packages, you will not have to be concerned about silent data corruption since we use ZFS - a high level file system that checks all the files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The 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 if it detects a damaged copy, it replaces it with a healthy one from another drive. This happens right away, so there will be no danger for any part of your content at any moment. By comparison, all the other file systems perform checks after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you could lose critical information. Since this isn't the case with ZFS, we're able to guarantee the integrity of each and every file you upload no matter what.
