Data corruption is the accidental change of a file or the losing of information that usually occurs during reading or writing. The reason can be hardware or software fail, and as a consequence, a file could become partially or completely corrupted, so it will no longer work correctly since its bits will be scrambled or lacking. 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 for the reason that its content will be unreadable, etc. When this kind of an issue appears and it's not noticed by the system or by an admin, the data will become corrupted silently and if this happens on a disk drive that is part of a RAID array where the data is synced between various different drives, the corrupted file shall be reproduced on all of the other drives and the damage will become permanent. Numerous frequently used file systems either do not offer real-time checks or do not have high quality ones which can detect a problem before the damage is done, so silent data corruption is a rather common issue on hosting servers where substantial amounts of information are stored.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data that you upload to your new cloud hosting account will be ensured by the ZFS file system that we employ on our cloud platform. The vast majority of internet hosting providers, including our company, use multiple HDDs to keep content and because the drives work in a RAID, identical information is synchronized between the drives at all times. In case a file on a drive gets corrupted for reasons unknown, however, it is very likely that it will be duplicated on the other drives because other file systems don't feature special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the bad copy shall be replaced with a good one from a different drive. Because this happens instantly, there's no risk for any of your files to ever get corrupted.
