Data corruption is the damage of info because of various hardware or software fails. When a file gets damaged, it will no longer function as it should, so an application will not start or shall give errors, a text file shall be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an admin, which makes it a serious problem for web hosting servers as failures are more likely to happen on larger hard disk drives where vast volumes of info are stored. When a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as a healthy one and it'll be copied on all the drives, making the damage permanent. A lot of the file systems which operate on web servers nowadays often cannot discover corrupted files right away or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your websites in a shared hosting account with our company, you don't need to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform uses the leading-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All information that you upload will be stored in a RAID i.e. simultaneously on a large number of SSD drives. All the file systems synchronize the files between the different drives with this kind of a setup, but there is no real guarantee that a file will not be corrupted. This may happen at the time of the writing process on any drive and then a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all drives instantly and in the event that a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. In this way, your data will continue to be unharmed no matter what, even if an entire drive fails.
