Data corruption is the unintentional transformation of a file or the loss of information that often occurs during reading or writing. The reason can be hardware or software malfunction, and for that reason, a file can become partially or entirely corrupted, so it will no longer function correctly as its bits shall be scrambled or lost. An image file, for example, will no longer show an authentic image, but a random mix 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 recognized by the system or by an admin, the data will be corrupted silently and in case this happens on a drive which is part of a RAID array where the information is synchronized between various different drives, the corrupted file shall be copied on all the other drives and the damage will be long term. A large number of widespread file systems either do not feature real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a rather common issue on web hosting servers where huge amounts of data are stored.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data which you upload to your new cloud hosting account will be ensured by the ZFS file system that we take advantage of on our cloud platform. Most hosting service providers, including our company, use multiple hard drives to store content and considering that the drives work in a RAID, the exact same info is synchronized between the drives at all times. When a file on a drive is corrupted for reasons unknown, yet, it is likely that it will be duplicated on the other drives since alternative file systems do not have special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy will be replaced with a good one from a different hard disk drive. Since this happens instantly, there is no risk for any of your files to ever get corrupted.
