Data corruption is the damage of info because of various software or hardware failures. Once a file is corrupted, it will no longer function properly, so an app will not start or shall give errors, a text file shall be partially or completely 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 acknowledgement by the system or an administrator, that makes it a serious problem for hosting servers as fails are more likely to occur on bigger hard disk drives where substantial volumes of information are stored. In case a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as a regular one and it will be duplicated on all the drives, making the damage permanent. A lot of the file systems that operate on web servers these days often are not able to recognize corrupted files instantly or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Web Hosting

If you host your websites in a cloud web hosting account with our firm, you won't need to worry about any of your data ever getting corrupted. We can guarantee that because our cloud hosting platform uses the revolutionary ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. All of the data that you upload will be stored in a RAID i.e. simultaneously on numerous NVMes. All of the file systems synchronize the files between the separate drives using such a setup, but there's no real warranty that a file will not be corrupted. This can happen at the time of the writing process on any drive and afterwards a bad copy may be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all drives in real time and in the event that a corrupted file is discovered, it's replaced with a good copy with the correct checksum from another drive. In this way, your info will stay undamaged no matter what, even if an entire drive fails.
