Data corruption is the damage of data because of various software or hardware problems. After a file gets corrupted, it will no longer function accurately, so an app will not start or shall give errors, a text file shall be partially or completely unreadable, an archive file will be impossible to open 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 web hosting servers as failures are much more likely to happen on larger in size hard drives where large volumes of information are placed. When a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it's more than likely that the damaged file will be treated as an undamaged one and it will be duplicated on all the drives, making the damage permanent. Lots of the file systems which run on web servers today often are unable to identify corrupted files right away or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account will be ensured by the ZFS file system which we make use of on our cloud platform. The majority of internet hosting service providers, including our company, use multiple hard drives to keep content and considering that the drives work in a RAID, identical information is synchronized between the drives at all times. If a file on a drive is damaged for reasons unknown, however, it is more than likely that it will be duplicated on the other drives since other file systems do not feature special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, and the bad copy will be swapped with a good one from a different hard disk. Because this happens immediately, there is no possibility for any of your files to ever get corrupted.
