Data corruption is the damage of data caused by various software or hardware problems. The moment a file is damaged, it will no longer function properly, 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 data getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for web hosting servers as failures are more likely to happen on larger in size hard drives where large volumes of info 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's very likely that the damaged file will be treated as a regular one and it will be copied on all drives, making the harm permanent. A huge number of the file systems which operate on web servers today often cannot find corrupted files instantly or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your Internet sites in a shared hosting account with our firm, you don't have to worry about any of your data ever getting corrupted. We can ensure that as our cloud hosting platform uses the amazing ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for every single file. Any kind of data that you upload will be saved in a RAID i.e. simultaneously on many NVMes. 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 will not get corrupted. This may occur at the time of the writing process on any drive and then a bad copy may be copied on all other drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all of the drives live and in case a corrupted file is found, it is replaced with a good copy with the correct checksum from another drive. In this way, your information will continue to be unharmed no matter what, even if a whole drive fails.
