Data corruption is the damage of data due to various hardware or software fails. The moment a file is damaged, it will no longer work correctly, so an app will not start or will give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as fails are more likely to occur on larger in size hard disk drives where substantial volumes of information are stored. When a drive is part of a RAID and the info on it is copied on other drives for redundancy, it is very likely that the bad file will be treated as a good one and it'll be copied on all drives, making the harm permanent. A lot of the file systems that operate on web servers nowadays often are not able to detect corrupted files instantly or they need time-consuming system checks during which the server isn't working.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data which you upload to your new cloud hosting account will be guaranteed by the ZFS file system which we take advantage of on our cloud platform. The vast majority of hosting service providers, including our company, use multiple hard disk drives to keep content and because the drives work in a RAID, the exact same information is synchronized between the drives all the time. If a file on a drive becomes damaged for reasons unknown, however, it's more than likely that it will be reproduced on the other drives since alternative file systems don't feature special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each file. In the event that 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 another hard disk. Because this happens immediately, there is no risk for any of your files to ever get corrupted.
