Data corruption is the unintentional modification of a file or the loss of information that usually occurs during reading or writing. The reason can be hardware or software failure, and due to this fact, a file can become partially or completely corrupted, so it will no longer work correctly because its bits will be scrambled or lost. 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 as its content will be unreadable, etc. When such an issue occurs and it's not found by the system or by an administrator, the data will get corrupted silently and when this happens on a drive which is a part of a RAID array where the info is synced between different drives, the corrupted file shall be duplicated on all of the other drives and the damage will become permanent. A large number of popular file systems either do not offer real-time checks or do not have high quality ones that can detect a problem before the damage is done, so silent data corruption is a rather common matter on web hosting servers where large amounts of information are kept.
No Data Corruption & Data Integrity in Shared Website Hosting
We guarantee the integrity of the data uploaded in every single shared website hosting account which is made on our cloud platform as we work with the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption via a unique checksum for every single file. We shall store your information on a large number of NVMe drives that operate in a RAID, so the exact same files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all the 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 swaps that file with a healthy copy from some other drive in the RAID. There's no other file system which uses checksums, so it's possible for data to get silently corrupted and the bad file to be duplicated on all drives over time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not need to deal with any silent data corruption issues whatsoever should you obtain one of our semi-dedicated hosting plans due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to guarantee that all the files are undamaged at all times. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. Because we store all content on a number of drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any possibility of the bad copy to be synchronized on the remaining hard disks. ZFS is the sole file system on the market that uses checksums, which makes it far superior to other file systems which are not able to identify silent data corruption and duplicate bad files across hard drives.
