Data corruption is the damage of info due to various software or hardware problems. The moment a file gets damaged, it will no longer work as it should, so an application will not start or will give errors, a text file shall be partially or entirely 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, that makes it a serious problem for website hosting servers as failures are more likely to happen on larger in size hard drives where considerable volumes of info are kept. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as a standard one and it will be copied on all drives, making the harm permanent. A lot of the file systems which run on web servers these days often are not able to detect corrupted files in real time or they need time-consuming system checks through which the server is not operational.
No Data Corruption & Data Integrity in Shared Website Hosting
The integrity of the data which you upload to your new shared website hosting account will be guaranteed by the ZFS file system that we use on our cloud platform. The vast majority of hosting providers, like our company, use multiple hard disk drives to store content and because the drives work in a RAID, identical data is synchronized between the drives all of the time. When a file on a drive is damaged for reasons unknown, yet, it is very likely that it will be duplicated on the other drives since alternative file systems don't feature special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each and every 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 will be replaced with a good one from a different drive. As this happens right away, there's no possibility for any of your files to ever be corrupted.
