Data corruption is the unintended change of a file or the losing of info that often occurs during reading or writing. The reason could be hardware or software failure, and as a result, a file may become partially or completely corrupted, so it'll no longer function properly as its bits shall be scrambled or lacking. An image file, for instance, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. When such a problem occurs and it is not recognized by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that's a part of a RAID array where the data is synchronized between various different drives, the corrupted file shall be copied on all of the other drives and the damage will become long term. Numerous popular file systems either do not feature real-time checks or don't have good ones that will detect a problem before the damage is done, so silent data corruption is a rather common issue on hosting servers where large volumes of information are stored.
No Data Corruption & Data Integrity in Web Hosting
The integrity of the data which you upload to your new web hosting account will be guaranteed by the ZFS file system which we use on our cloud platform. The vast majority of hosting service providers, like our firm, use multiple hard disk drives to store content and since the drives work in a RAID, identical information is synchronized between the drives all the time. In case a file on a drive is corrupted for some reason, however, it is likely that it will be reproduced on the other drives since alternative file systems do not offer special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each and every file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the damaged copy shall be replaced with a good one from a different disk drive. Due to the fact that this happens immediately, there's no possibility for any of your files to ever be damaged.
