Data corruption is the accidental change of a file or the losing of info which usually occurs during reading or writing. The reason may be hardware or software fail, and as a result, a file could become partially or entirely corrupted, so it will no longer work correctly since its bits shall be scrambled or lost. An image file, for example, will no longer display an accurate image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In case this kind of a problem appears and it isn't identified by the system or by an admin, the data will become corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the data is synchronized between various different drives, the corrupted file shall be reproduced on all the other drives and the harm will be long term. Many widespread file systems either do not feature real-time checks or don't have good ones which will detect a problem before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where substantial volumes of info are stored.
No Data Corruption & Data Integrity in Shared Website Hosting
We warrant the integrity of the info uploaded in any shared website hosting
account that is made on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We'll store your information on multiple SSD drives which operate in a RAID, so the very same files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all the files on all the drives in real time and if the checksum of any file is different from what it has to be, the file system swaps that file with a healthy copy from some other drive from the RAID. There's no other file system which uses checksums, so it's easy for data to get silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you don't have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any probability of files getting corrupted silently because the servers where your semi-dedicated server
account will be created work with a powerful file system called ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since 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. When there is a mismatch, the damaged copy is replaced with a good one from one of the other drives and since this happens right away, there is no chance that a damaged copy can remain on our web hosting servers or that it could be copied to the other drives in the RAID. None of the other file systems employ this type of checks and in addition, even during a file system check right after a sudden power loss, none of them can discover silently corrupted files. In contrast, ZFS won't crash after an electrical power failure and the regular checksum monitoring makes a lenghty file system check obsolete.
