Data corruption is the unintentional modification of a file or the losing of info that often occurs during reading or writing. The reason could be hardware or software malfunction, and for that reason, a file may become partially or entirely corrupted, so it will no longer function correctly since its bits shall be scrambled or missing. An image file, for example, 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, etcetera. If this kind of a problem appears and it is not found by the system or by an administrator, the data will be corrupted silently and if this happens on a drive that's part of a RAID array where the data is synchronized between different drives, the corrupted file shall be reproduced on all the other drives and the harm will become permanent. A large number of widespread file systems either do not 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 rather common problem on web hosting servers where huge volumes of information are stored.
No Data Corruption & Data Integrity in Cloud Hosting
We warrant the integrity of the info uploaded in each and every cloud hosting account that is made on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption via a unique checksum for each and every file. We will store your data on a large number of SSD drives which work in a RAID, so the exact same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all the files on all the 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 a different drive in the RAID. No other file system uses checksums, so it is easy for data to be silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any risk of files getting damaged silently because the servers where your semi-dedicated hosting account will be created employ a powerful file system called ZFS. Its key advantage over other file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. Since we store 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 good one from one of the other drives and because it happens instantly, there is no chance that a corrupted copy can remain on our web servers or that it can be copied to the other hard drives in the RAID. None of the other file systems include this type of checks and what's more, even during a file system check right after a sudden blackout, none of them can discover silently corrupted files. In comparison, ZFS will not crash after a power failure and the constant checksum monitoring makes a time-consuming file system check unnecessary.
