Data corruption is the damage of info due to various software or hardware problems. The moment a file gets corrupted, it will no longer work correctly, so an application will not start or will give errors, a text file shall be partially or entirely unreadable, an archive will be impossible to open and 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 hosting servers as failures are more likely to happen on bigger hard disks where considerable volumes of information are located. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it's likely that the bad file will be treated as a good one and it will be duplicated on all the drives, making the harm permanent. Lots of the file systems which operate on web servers today often cannot find corrupted files in real time or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Hosting

If you host your Internet sites in a hosting account with our firm, you will not need to worry about any of your data ever getting damaged. We can ensure that since our cloud hosting platform uses the cutting-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. All the information that you upload will be saved in a RAID i.e. simultaneously on multiple SSDs. A lot of file systems synchronize the files between the separate drives with such a setup, but there's no real warranty that a file won't get corrupted. This may happen during the writing process on each drive and then a damaged copy may be copied on the other drives. What is different on our platform is that ZFS examines the checksums of all files on all drives live and in the event that a corrupted file is found, it is replaced with a good copy with the correct checksum from some other drive. By doing this, your info will stay intact no matter what, even if a whole drive fails.
