Data corruption is the unintended change of a file or the loss of information that often occurs during reading or writing. The reason may be hardware or software failure, and consequently, a file may become partially or fully corrupted, so it'll no longer work properly since its bits will be scrambled or lacking. An image file, for example, will no longer show a real image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. If this kind of a problem appears and it's not recognized by the system or by an admin, the data will become corrupted silently and in case this happens on a disk drive which is a part of a RAID array where the data is synced between various drives, the corrupted file will be copied on all the other drives and the damage will become permanent. Numerous frequently used file systems either don't feature real-time checks or do not have good ones which will detect a problem before the damage is done, so silent data corruption is a very common matter on hosting servers where huge amounts of data are kept.

No Data Corruption & Data Integrity in Cloud Website Hosting

We warrant the integrity of the information uploaded in any cloud website hosting account which is generated on our cloud platform because we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We will store your data on a large number of SSD drives which function in a RAID, so identical files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all files on all drives in real time and in the event that the checksum of any file is different from what it has to be, the file system replaces that file with a healthy version from another drive in 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 won't have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any possibility of files getting damaged silently due to the fact that the servers where your semi-dedicated server account will be created employ a powerful file system named ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for every single file - a digital fingerprint which is checked in real time. As we save all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has stored. When 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's no chance that a damaged copy can remain on our web hosting servers or that it can be copied to the other drives in the RAID. None of the other file systems work with this type of checks and in addition, even during a file system check right after a sudden electrical power failure, none of them can find silently corrupted files. In comparison, ZFS will not crash after a blackout and the regular checksum monitoring makes a lenghty file system check obsolete.
