Data corruption is the damage of information because of various software or hardware fails. The moment a file is corrupted, it will no longer function correctly, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive will be impossible to open and 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 web hosting servers as fails are much more likely to occur on larger in size hard disk drives where considerable 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 bad file will be treated as an ordinary one and it will be copied on all of the drives, making the damage permanent. A huge number of the file systems that operate on web servers nowadays often are not able to detect corrupted files in real time or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data that you upload to your new cloud hosting account will be guaranteed by the ZFS file system which we use on our cloud platform. The majority of web hosting providers, including our firm, use multiple HDDs to keep content and considering that the drives work in a RAID, the same info is synchronized between the drives all the time. If a file on a drive gets damaged for reasons unknown, yet, it is more than likely that it will be duplicated on the other drives because alternative file systems don't offer special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the damaged copy shall be replaced with a good one from a different drive. Since this happens in real time, there is no possibility for any of your files to ever get damaged.
