Data corruption is the accidental modification of a file or the loss of info that usually occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file could become partially or completely corrupted, so it will no longer function properly as its bits shall be scrambled or missing. An image file, for example, will no longer present an accurate image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In case such a problem occurs and it's not found by the system or by an admin, the data will be corrupted silently and when this happens on a drive that's a part of a RAID array where the info is synchronized between different drives, the corrupted file shall be copied on all of the other drives and the damage will become permanent. A large number of frequently used file systems either do not feature real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where substantial volumes of info are stored.
No Data Corruption & Data Integrity in Cloud Web Hosting
The integrity of the data that you upload to your new cloud web hosting account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. The majority of web hosting providers, like our company, use multiple hard disks to keep content and because the drives work in a RAID, exactly the same info is synchronized between the drives all of the time. If a file on a drive is damaged for whatever reason, however, it's likely that it will be reproduced on the other drives because other file systems don't feature special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for every single file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the damaged copy will be swapped with a good one from a different hard disk. Because this happens instantly, there's no possibility for any of your files to ever be damaged.
