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 consequently, a file may become partially or entirely corrupted, so it will no longer function correctly because its bits shall be scrambled or lacking. An image file, for example, will no longer display an actual image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etc. In case such an issue 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's part of a RAID array where the data is synced between different drives, the corrupted file will be duplicated on all of the other drives and the harm will become long term. A large number of widespread file systems either do not feature real-time checks or don't have good ones which can detect a problem before the damage is done, so silent data corruption is a common matter on hosting servers where huge volumes of info are kept.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the info uploaded in every single shared hosting account which is created on our cloud platform since we use the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption via a unique checksum for each and every file. We will store your info on multiple NVMe drives that function in a RAID, so the very same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all files on all drives in real time and in case the checksum of any file is different from what it needs to be, the file system swaps that file with an undamaged copy from some other drive inside the RAID. There's no other file system that uses checksums, so it is easy for data to get silently corrupted and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting damaged silently as the servers where your semi-dedicated hosting account will be created use a powerful file system known as ZFS. Its advantage over other file systems is that it uses a unique checksum for every single file - a digital fingerprint that is checked in real time. As we save all content on multiple NVMe drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has saved. If there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that this happens in real time, there is no chance that a corrupted copy can remain on our web servers or that it can be duplicated to the other hard drives in the RAID. None of the other file systems include this type of checks and furthermore, even during a file system check after an unexpected power loss, none of them can find silently corrupted files. In contrast, ZFS doesn't crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check unnecessary.
