Data corruption is the damage of info due to various hardware or software problems. The moment a file is corrupted, it will no longer function accurately, so an application will not start or shall give errors, a text file will be partially or completely unreadable, an archive will be impossible to open then 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 serious problem for website hosting servers as failures are more likely to happen on bigger hard disk drives where considerable volumes of information are stored. When a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it's very likely that the damaged file will be treated as an ordinary one and it'll be duplicated on all the drives, making the damage permanent. Lots of the file systems which operate on web servers today often are unable to find corrupted files in real time or they need time-consuming system checks during which the server isn't functioning.
No Data Corruption & Data Integrity in Shared Website Hosting
The integrity of the data which you upload to your new shared website hosting account shall be ensured by the ZFS file system which we make use of on our cloud platform. Most of the internet hosting suppliers, including our firm, use multiple hard drives to store content and because the drives work in a RAID, identical data is synchronized between the drives at all times. When a file on a drive gets damaged for whatever reason, yet, it's likely that it will be duplicated on the other drives since alternative file systems don't have special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the bad copy shall be swapped with a good one from a different drive. Because this happens immediately, there is no possibility for any of your files to ever be damaged.
