Data corruption is the damage of info because of various software or hardware problems. Once a file gets damaged, it will no longer work correctly, so an application will not start or will give errors, a text file will be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an admin, which makes it a significant problem for website hosting servers as problems are more likely to happen on larger hard drives where substantial volumes of information are located. When a drive is a part of a RAID and the data on it is copied 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 of the drives, making the harm permanent. A huge number of the file systems that operate on web servers nowadays often are not able to locate corrupted files in real time or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Cloud Web Hosting
If you host your sites in a cloud web hosting account with our company, you do not need to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform uses the advanced ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on many SSDs. All file systems synchronize the files between the separate drives with such a setup, but there's no real guarantee that a file won't be corrupted. This may happen at the time of the writing process on any drive and after that a bad copy can be copied on the other drives. What is different on our platform is that ZFS analyzes the checksums of all files on all drives instantly and in case a corrupted file is found, it is substituted with a good copy with the correct checksum from another drive. That way, your info will stay unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you obtain one of our semi-dedicated server plans, you will not have to be concerned about silent data corruption as we use ZFS - a high level file system which monitors 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 couple 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 in case it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no risk for any part of your content at any time. In contrast, all of 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 cannot detect silently corrupted files, so a bad copy could be replicated on the other disks as well and you can lose important information. Since this isn't the case with ZFS, we're able to guarantee the integrity of each file you upload no matter what.
