Data corruption is the accidental change of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software failure, and due to this fact, a file can become partially or completely corrupted, so it'll no longer function as it should as its bits will be scrambled or missing. An image file, for example, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. When such an issue appears and it isn't identified by the system or by an administrator, the data will be corrupted silently and if this happens on a drive that's part of a RAID array where the data is synchronized between various drives, the corrupted file shall be duplicated on all other drives and the damage will be permanent. Many widespread file systems either do not feature 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 very common issue on internet hosting servers where large amounts of information are stored.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most internet hosting suppliers, like our company, use multiple hard disk drives to store content and considering that the drives work in a RAID, exactly the same data is synchronized between the drives all the time. If a file on a drive is damaged for reasons unknown, however, it is likely that it will be copied on the other drives since alternative file systems don't offer special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the bad copy shall be replaced with a good one from another hard disk drive. As this happens immediately, there is no risk for any of your files to ever be damaged.
