Data corruption is the accidental change of a file or the loss of information that usually occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file may become partially or completely corrupted, so it will no longer function correctly since its bits will be scrambled or lost. An image file, for example, will no longer present a real image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. If such an issue appears and it isn't found by the system or by an administrator, the data will become corrupted silently and if this happens on a disk drive which is a part of a RAID array where the information is synced between various different drives, the corrupted file will be replicated on all the other drives and the damage will be long term. Numerous widely used file systems either don't feature real-time checks or do not have good ones that will detect an issue before the damage is done, so silent data corruption is a common matter on web hosting servers where large amounts of information are stored.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data which you upload to your new shared web hosting account shall be ensured by the ZFS file system that we employ on our cloud platform. The vast majority of web hosting providers, including our firm, use multiple hard disks to keep content and because the drives work in a RAID, identical data is synchronized between the drives at all times. If a file on a drive gets corrupted for whatever reason, however, it's likely that it will be duplicated on the other drives since other file systems don't feature special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for every single file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the bad copy will be substituted with a good one from another hard disk drive. Due to the fact that this happens in real time, there's no risk for any of your files to ever be damaged.
