Data corruption is the accidental modification of a file or the loss of information that usually occurs during reading or writing. The reason may be hardware or software malfunction, and for that reason, a file can become partially or completely corrupted, so it'll no longer function correctly because its bits will be scrambled or missing. An image file, for example, will no longer display a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. When such a problem appears and it isn't found by the system or by an admin, the data will be corrupted silently and in case this happens on a drive that is a part of a RAID array where the information is synchronized between various different drives, the corrupted file will be replicated on all of the other drives and the damage will become long term. Numerous popular file systems either don't feature real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a common matter on hosting servers where substantial volumes of data are stored.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data that you upload to your new cloud hosting account shall be guaranteed by the ZFS file system which we use on our cloud platform. Most internet hosting suppliers, including our company, use multiple hard disk drives to store content and since the drives work in a RAID, the same data is synchronized between the drives at all times. If a file on a drive gets damaged for reasons unknown, yet, it is very likely that it will be reproduced on the other drives because other file systems do not feature special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the bad copy will be swapped with a good one from another drive. As this happens right away, there is no possibility for any of your files to ever get corrupted.
