Data corruption is the damage of info caused by various hardware or software problems. The moment a file gets damaged, it will no longer work properly, so an application will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting harmed without any identification by the system or an admin, that makes it a significant problem for website hosting servers as fails are more likely to happen on bigger hard drives where vast volumes of information are kept. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's very likely that the bad file will be treated as a regular one and it'll be duplicated on all drives, making the harm permanent. A lot of the file systems that operate on web servers today often cannot find corrupted files immediately or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Cloud Web Hosting

In case you host your websites in a cloud web hosting account with our firm, you don't have to worry about any of your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform works with the amazing ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All the data that you upload will be saved in a RAID i.e. simultaneously on a number of NVMes. All file systems synchronize the files between the separate drives with this kind of a setup, but there is no real warranty that a file will not be corrupted. This may occur at the time of the writing process on any drive and afterwards a bad copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives instantly and when a corrupted file is identified, it's substituted with a good copy with the correct checksum from some other drive. That way, your information will remain intact no matter what, even if an entire drive fails.
