Data corruption is the unintentional transformation of a file or the losing of information that often occurs during reading or writing. The reason could be hardware or software malfunction, and due to this fact, a file can become partially or entirely corrupted, so it'll no longer work as it should as 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 as its content will be unreadable, etcetera. In the event that such a problem appears and it is not noticed by the system or by an administrator, the data will be corrupted silently and when this happens on a disk drive that is a part of a RAID array where the data is synced between various different drives, the corrupted file shall be reproduced on all of the other drives and the damage will be long term. Numerous frequently used file systems either do not feature real-time checks or do not have high quality ones that can detect an issue before the damage is done, so silent data corruption is a very common matter on internet hosting servers where huge amounts of info are kept.

No Data Corruption & Data Integrity in Website Hosting

If you host your websites in a website hosting account from our company, you will not need to worry about any of your data ever getting damaged. We can guarantee that since our cloud hosting platform employs the reliable ZFS file system. The latter is the only file system that uses checksums, or unique digital fingerprints, for each file. Any info that you upload will be saved in a RAID i.e. simultaneously on many SSDs. A lot of file systems synchronize the files between the separate drives using such a setup, but there's no real warranty that a file will not get corrupted. This can happen during the writing process on any drive and after that a corrupted copy may be copied on the rest of the drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all of the drives live and in case a corrupted file is located, it is replaced with a good copy with the correct checksum from another drive. This way, your info will remain intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any chance of files getting damaged silently since the servers where your semi-dedicated server account will be created employ a powerful file system known as ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we save all content on a number of SSD 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 saved. In case there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and because this happens in real time, there is no chance that a damaged copy can remain on our website hosting servers or that it can be copied to the other hard disks in the RAID. None of the other file systems work with this kind of checks and furthermore, even during a file system check after an unexpected blackout, none of them will detect silently corrupted files. In contrast, ZFS won't crash after a power failure and the regular checksum monitoring makes a lenghty file system check obsolete.
