Data corruption is the unintentional change of a file or the loss of info that usually occurs during reading or writing. The reason can be hardware or software failure, and as a consequence, a file could become partially or fully corrupted, so it will no longer function correctly as its bits shall be scrambled or lost. An image file, for instance, will no longer display an authentic image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In case this kind of a problem appears and it's not found by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive that is a part of a RAID array where the info is synchronized between various drives, the corrupted file shall be duplicated on all of the other drives and the harm will become long term. A number of commonly used file systems either do not offer real-time checks or do not have good ones which will detect a problem before the damage is done, so silent data corruption is a common problem on hosting servers where substantial amounts of data are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data which you upload to your new cloud web hosting account shall be guaranteed by the ZFS file system that we work with on our cloud platform. Most internet hosting providers, including our firm, use multiple hard drives to keep content and since the drives work in a RAID, exactly the same info is synchronized between the drives all of the time. In case a file on a drive gets damaged for reasons unknown, however, it is very likely that it will be copied on the other drives as other file systems don't feature special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every single file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, and the bad copy shall be replaced with a good one from another drive. Because this happens immediately, there is no possibility for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility of files getting damaged silently since the servers where your semi-dedicated hosting account will be created use a powerful file system named ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we keep all content on a number of SSD drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has saved. In the event that there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and because it happens in real time, there is no chance that a damaged copy could remain on our servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems employ this type of checks and in addition, even during a file system check following an unexpected power loss, none of them will find silently corrupted files. In comparison, ZFS won't crash after a blackout and the constant checksum monitoring makes a lenghty file system check unneeded.
