Data corruption is the accidental change of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software malfunction, and as a consequence, a file could become partially or fully corrupted, so it'll no longer function properly since its bits shall be scrambled or missing. An image file, for instance, 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, and so on. If this kind of a problem appears and it isn't recognized by the system or by an admin, the data will become corrupted silently and when this happens on a disk drive that's part of a RAID array where the information is synchronized between various drives, the corrupted file shall be replicated on all of the other drives and the damage will be permanent. Many popular file systems either don't feature real-time checks or do not have high quality ones which will detect an issue before the damage is done, so silent data corruption is a very common problem on hosting servers where substantial volumes of data are stored.

No Data Corruption & Data Integrity in Web Hosting

We guarantee the integrity of the info uploaded in any web hosting account that is created on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption using a unique checksum for each file. We'll store your information on multiple NVMe drives that operate in a RAID, so the very same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system swaps that file with a healthy copy from another drive in the RAID. There's no other file system which uses checksums, so it is easy for data to get silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you will not have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any possibility of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created use a powerful file system named ZFS. Its advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that is checked in real time. Since we save all content on a number of NVMe drives, ZFS checks if the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. If there's a mismatch, the bad 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 can remain on our hosting servers or that it can be duplicated to the other drives in the RAID. None of the other file systems employ this type of checks and in addition, even during a file system check following a sudden electrical power failure, none of them will detect silently corrupted files. In comparison, ZFS doesn't crash after an electrical power failure and the constant checksum monitoring makes a time-consuming file system check unneeded.
