Data corruption is the accidental change of a file or the losing of information which usually occurs during reading or writing. The reason may be hardware or software fail, and consequently, a file may become partially or entirely corrupted, so it'll no longer function as it should as its bits shall be scrambled or lacking. An image file, for instance, will no longer show 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. In case this kind of a problem appears and it isn't found by the system or by an admin, the data will be corrupted silently and in case this happens on a drive that is part of a RAID array where the info is synchronized between various drives, the corrupted file shall be copied on all other drives and the damage will be long term. A number of widely used file systems either do not have real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a common matter on hosting servers where large volumes of data are stored.

No Data Corruption & Data Integrity in Shared Website Hosting

In case you host your sites in a shared website hosting account with our firm, you don't need to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform works with the leading-edge ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All of the information that you upload will be stored in a RAID i.e. simultaneously on a large number of SSD drives. All the file systems synchronize the files between the different drives with this type of a setup, but there is no real guarantee that a file won't be corrupted. This can occur during the writing process on each drive and then a bad copy can be copied on all other drives. What is different on our platform is that ZFS compares the checksums of all files on all drives immediately and if a corrupted file is located, it is replaced with a good copy with the correct checksum from another drive. That way, your data will continue to be unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any risk of files getting corrupted silently due to the fact that the servers where your semi-dedicated server account will be created use a powerful file system called ZFS. Its key advantage over various other 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 keep all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. In case there is a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since it happens right away, there is no chance that a corrupted copy could remain on our web hosting servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems include this kind of checks and in addition, even during a file system check right after an unexpected power loss, none of them can detect silently corrupted files. In comparison, ZFS doesn't crash after a power failure and the continual checksum monitoring makes a lenghty file system check unneeded.
