Data corruption is the unintended change of a file or the loss of information that usually occurs during reading or writing. The reason could be hardware or software failure, and as a result, a file could become partially or entirely corrupted, so it'll no longer function properly as its bits shall be scrambled or missing. An image file, for instance, will no longer present a real 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. In case this kind of an issue occurs and it is not identified by the system or by an admin, the data will be corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the information is synchronized between different drives, the corrupted file shall be copied on all the other drives and the damage will be permanent. A large number of widespread file systems either don't feature real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a rather common issue on web hosting servers where large volumes of information are stored.

No Data Corruption & Data Integrity in Cloud Hosting

We guarantee the integrity of the info uploaded in every single cloud hosting account that is generated on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption using a unique checksum for each file. We will store your data on a large number of NVMe drives which operate in a RAID, so identical files will exist on several places at the same time. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file is different from what it has to be, the file system replaces that file with a healthy version from a different drive from the RAID. There's no other file system which uses checksums, so it is possible for data to be silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any risk of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created use a powerful file system called ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. Since we keep 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 remaining drives and the one it has stored. If there's a mismatch, the bad copy is replaced with a good one from one of the other drives and considering that it happens right away, there is no chance that a corrupted copy can remain on our hosting servers or that it can be copied to the other hard disks in the RAID. None of the other file systems include this kind of checks and what is more, even during a file system check following an unexpected blackout, none of them will find silently corrupted files. In comparison, ZFS doesn't crash after a power loss and the constant checksum monitoring makes a lenghty file system check obsolete.
