Data corruption is the accidental transformation of a file or the loss of info which often occurs during reading or writing. The reason could be hardware or software malfunction, and because of this, a file could become partially or fully corrupted, so it'll no longer function correctly because its bits will be scrambled or lacking. 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. If such an issue appears and it is not identified by the system or by an administrator, the data will be corrupted silently and in case this happens on a disk drive which is part of a RAID array where the data is synchronized between various different drives, the corrupted file will be reproduced on all other drives and the damage will become permanent. A number of widely used file systems either don't have real-time checks or do not have good ones that can detect an issue before the damage is done, so silent data corruption is a common issue on hosting servers where huge amounts of info 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 guaranteed by the ZFS file system that we employ on our cloud platform. Most of the internet hosting service providers, like our firm, use multiple hard disks to store content and since the drives work in a RAID, exactly the same data is synchronized between the drives all of the time. In case a file on a drive gets corrupted for whatever reason, however, it's more than likely that it will be copied on the other drives as alternative file systems don't feature special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the bad copy shall be swapped with a good one from another hard drive. Due to the fact that this happens instantly, there's no risk for any of your files to ever get corrupted.
