Data corruption is the accidental change of a file or the loss of information which often occurs during reading or writing. The reason could be hardware or software failure, and due to this fact, a file may become partially or completely corrupted, so it will no longer function correctly because its bits shall be scrambled or missing. 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 because its content will be unreadable, etc. In case such an issue appears and it isn't recognized by the system or by an admin, the data will get corrupted silently and when this happens on a drive which is part of a RAID array where the information is synchronized between various drives, the corrupted file will be replicated on all the other drives and the damage will be permanent. Numerous popular file systems either don't have real-time checks or do not have high quality ones that will detect an issue before the damage is done, so silent data corruption is a rather common problem on hosting servers where substantial volumes of data are kept.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting
account will be guaranteed by the ZFS file system that we work with on our cloud platform. Most of the internet hosting suppliers, like our firm, use multiple hard drives to keep content and since the drives work in a RAID, identical information is synchronized between the drives all of the time. When a file on a drive becomes corrupted for reasons unknown, yet, it's likely that it will be copied on the other drives because alternative file systems do not have special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each and every file. In the event that a file gets corrupted, 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. As this happens instantly, there's no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any probability of files getting corrupted silently as the servers where your semi-dedicated hosting
account will be created take advantage of a powerful file system named ZFS. Its key advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we store all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. When there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since this happens right away, there is no chance that a damaged copy can remain on our website hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems work with such checks and what is more, even during a file system check after an unexpected blackout, none of them can discover silently corrupted files. In comparison, ZFS won't crash after a power loss and the constant checksum monitoring makes a time-consuming file system check unneeded.
