Data corruption is the damage of info caused by various software or hardware fails. After a file is damaged, it will no longer work correctly, 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 harmed without any identification by the system or an administrator, that makes it a significant problem for website hosting servers as problems are much more likely to happen on larger hard disks where large 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 is more than likely that the damaged file will be treated as a regular one and it'll be duplicated on all the drives, making the damage permanent. A huge number of the file systems which run on web servers these days often cannot recognize corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting account shall be guaranteed by the ZFS file system which we work with on our cloud platform. Most internet hosting providers, like our firm, use multiple hard drives to store content and because the drives work in a RAID, identical info is synchronized between the drives all of the time. In case a file on a drive is damaged for reasons unknown, yet, it is more than likely that it will be reproduced on the other drives since other file systems don't include special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the bad copy shall be replaced with a good one from another hard disk. Because this happens right away, there's no possibility for any of your files to ever get corrupted.
