Data corruption is the damage of information caused by various hardware or software failures. Once a file is damaged, it will no longer work properly, so an application will not start or will give errors, a text file can be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for web hosting servers as problems are much more likely to happen on larger hard disks where significant volumes of info are located. In case a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it's very likely that the bad file will be treated as an undamaged one and it will be copied on all the drives, making the harm permanent. A huge number of the file systems which run on web servers nowadays often are not able to detect corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Shared Web Hosting
If you host your websites in a shared web hosting
account with our company, you won't need to worry about any of your data ever getting corrupted. We can guarantee that since our cloud hosting platform employs the advanced ZFS file system. The aforementioned is the only file system that works with 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 a large number of SSDs. All of the file systems synchronize the files between the separate drives using this type of a setup, but there is no real guarantee that a file will not be corrupted. This may occur at the time of the writing process on each drive and then a bad copy may be copied on the other drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all the drives in real time and in the event that a corrupted file is discovered, it's replaced with a good copy with the correct checksum from another drive. By doing this, your data will continue to be intact no matter what, even if an entire drive fails.
