Data corruption is the damage of data due to various software or hardware failures. The moment a file is corrupted, it will no longer work as it should, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, which makes it a significant problem for website hosting servers as fails are very likely to happen on bigger hard drives where large volumes of info are placed. In case a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as a standard one and it'll be duplicated on all of the drives, making the harm permanent. A huge number of the file systems that operate on web servers today often are unable to locate corrupted files in real time or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Shared Web Hosting
If you host your Internet sites in a shared web hosting account with our firm, you will not need to worry about your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform employs the revolutionary ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any data that you upload will be kept in a RAID i.e. simultaneously on numerous SSD drives. All of the file systems synchronize the files between the different drives using such a setup, but there is no real warranty that a file will not be corrupted. This may occur during the writing process on each drive and then a corrupted copy can be copied on all other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all drives instantly and in the event that a corrupted file is identified, it's substituted with a good copy with the correct checksum from another drive. In this way, your info will stay undamaged no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you get one of our semi-dedicated server solutions, you won't have to worry about silent file corruption since we use ZFS - an advanced file system that monitors all 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. That file will be synchronized between several SSD drives for redundancy, so if one drive fails, the other ones will take over. 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 a different drive. This is done instantly, so there will be no risk for any part of your content at any time. By comparison, all of the other file systems perform checks after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the other disks as well and you may lose critical data. Since this is not the case with ZFS, we guarantee the integrity of each and every file you upload no matter what.
