Data corruption is the damage of information due to various hardware or software fails. Once a file gets damaged, it will no longer work correctly, so an app will not start or will give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for web hosting servers as failures are very likely to occur on larger in size hard disks where considerable volumes of info are placed. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it is very likely that the damaged file will be treated as a regular one and will be duplicated on all of the drives, making the damage permanent. A huge number of the file systems which operate on web servers these days often are unable to locate corrupted files immediately or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your Internet sites in a cloud hosting account with our firm, you will not need to worry about any of your data ever getting damaged. We can guarantee that because our cloud hosting platform employs the revolutionary ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. All information that you upload will be saved in a RAID i.e. simultaneously on numerous SSDs. All of the file systems synchronize the files between the separate drives with such a setup, but there is no real warranty that a file won't be corrupted. This could occur throughout the writing process on any drive and after that a bad copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all drives in real time and if a corrupted file is discovered, it is swapped with a good copy with the correct checksum from some other drive. In this way, your data will continue to be undamaged no matter what, even if an entire drive fails.
