Data corruption is the damage of information because of various software or hardware failures. After a file gets corrupted, it will no longer work accurately, so an app will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for website hosting servers as problems are much more likely to happen on larger hard disk drives where significant volumes of information are kept. When a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as a standard one and will be copied on all the drives, making the damage permanent. A lot of the file systems which operate on web servers today often cannot detect corrupted files right away or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

We have resolved the matter of silent data corruption on our cloud 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 on the market which checks all of the files instantly by employing 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 constantly examines the checksum of all files and in case any file is detected as damaged, it is 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 rest of the SSDs. ZFS needs a lot of physical memory to carry out the real-time checks and the benefit of our cloud hosting platform is that we use multiple powerful servers working together. If you host your Internet sites with us, your data will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

In case you buy one of our semi-dedicated server packages, you won't need to worry about silent file corruption as we use ZFS - a high level file system which monitors all the files in real time. Whenever you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between multiple 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 if it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no risk for any part of your content at any moment. By comparison, all the other file systems carry out checks only after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a corrupted copy could be replicated on the remaining drives as well and you could lose precious info. As this is not the case with ZFS, we are able to warrant the integrity of each file you upload no matter what.
