Data corruption is the damage of data caused by various hardware or software failures. The moment a file is damaged, it will no longer function accurately, so an app will not start or shall give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for web hosting servers as problems are more likely to occur on bigger hard disk drives where substantial volumes of info are stored. When a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it's very 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 lot of the file systems which operate on web servers these days often are unable to discover corrupted files in real time or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Website Hosting

If you host your sites in a website hosting account from our firm, you don't need to worry about your data ever getting corrupted. We can guarantee that due to the fact that our cloud hosting platform employs the state-of-the-art ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All the info that you upload will be kept in a RAID i.e. simultaneously on a large number of SSDs. All of the file systems synchronize the files between the different drives using this type of a setup, but there is no real warranty that a file won't be corrupted. This could happen at the time of the writing process on any drive and after that a bad copy can be copied on all other drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives in real time and when a corrupted file is discovered, it is replaced with a good copy with the correct checksum from some other drive. That way, your info will continue to be unharmed no matter what, even if a whole drive fails.
