Data corruption is the unintended modification of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software malfunction, and due to this fact, a file may become partially or completely corrupted, so it'll no longer function correctly because its bits shall be scrambled or lacking. 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 since its content will be unreadable, and so on. When such an issue occurs and it isn't recognized by the system or by an admin, the data will be corrupted silently and in case this happens on a drive which is part of a RAID array where the info is synced between various different drives, the corrupted file shall be duplicated on all other drives and the harm will be long term. Numerous frequently used file systems either don't have real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a rather common problem on internet hosting servers where large amounts of data are stored.

No Data Corruption & Data Integrity in Website Hosting

We guarantee the integrity of the data uploaded in every single website hosting account which is generated on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption using a unique checksum for each and every file. We shall store your info on a large number of SSD drives that work in a RAID, so identical files will be available on several places simultaneously. ZFS checks the digital fingerprint of all the 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 replaces that file with an undamaged copy from another drive inside 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 with time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any chance of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created employ 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. As we store all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. When there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and considering that this 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 drives in the RAID. None of the other file systems include this kind of checks and what is more, even during a file system check after an unexpected blackout, none of them will find silently corrupted files. In contrast, ZFS does not crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unneeded.
