Data corruption is the accidental transformation of a file or the loss of information that often occurs during reading or writing. The reason could be hardware or software malfunction, and consequently, a file may become partially or completely corrupted, so it'll no longer function correctly as its bits will be scrambled or missing. An image file, for instance, will no longer show a true image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In case this kind of a problem appears and it isn't identified by the system or by an administrator, the data will be corrupted silently and in case this happens on a drive that's part of a RAID array where the data is synced between different drives, the corrupted file shall be copied on all the other drives and the harm will become long term. Numerous widespread file systems either don't have real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a very common problem on internet hosting servers where huge volumes of info are kept.

No Data Corruption & Data Integrity in Cloud Website Hosting

If you host your sites in a cloud website hosting account from our company, you will not have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform uses the advanced ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. All the information that you upload will be stored in a RAID i.e. simultaneously on many different SSD drives. All file systems synchronize the files between the different drives using this type of a setup, but there's no real warranty that a file won't be corrupted. This could happen during the writing process on each drive and then a corrupted copy can be copied on all other drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all of the drives right away and in the event that a corrupted file is located, it's substituted with a good copy with the correct checksum from another drive. In this way, your information will stay unharmed no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We have avoided any possibility of files getting damaged silently as the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its key 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 keep all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. If there is a mismatch, the bad copy is replaced with a good one from one of the other drives and because it happens in real time, there is no chance that a corrupted copy could remain on our hosting servers or that it could 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 following a sudden power loss, none of them will detect silently corrupted files. In comparison, ZFS does not crash after an electrical power failure and the regular checksum monitoring makes a lenghty file system check obsolete.
