Data corruption is the unintentional transformation of a file or the loss of information that often occurs during reading or writing. The reason may be hardware or software malfunction, and due to this fact, a file can become partially or fully corrupted, so it'll no longer function properly because its bits will be scrambled or lost. An image file, for example, will no longer display an actual image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In the event that such an issue occurs and it is not noticed by the system or by an admin, the data will be corrupted silently and if this happens on a drive which is part of a RAID array where the info is synced between various drives, the corrupted file will be copied on all the other drives and the damage will be permanent. Many widely used file systems either don't offer 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 common matter on internet hosting servers where large volumes of info are kept.
No Data Corruption & Data Integrity in Shared Website Hosting
In case you host your Internet sites in a shared website hosting account with our company, you do not need to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform works with the amazing ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on a large number of NVMe drives. All of the file systems synchronize the files between the separate drives using such a setup, but there's no real guarantee that a file won't get corrupted. This may occur during the writing process on any drive and after that a bad copy can be copied on the rest of the drives. What is different on our platform is that ZFS compares the checksums of all files on all the drives instantly and when a corrupted file is discovered, it's substituted with a good copy with the correct checksum from some other drive. In this way, your information will continue to be unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any risk of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created employ a powerful file system named ZFS. Its key advantage over 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 store all content on multiple NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has stored. In the event that there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and because it happens instantly, there's no chance that a corrupted copy can remain on our servers or that it can be copied to the other hard drives in the RAID. None of the other file systems work with such checks and furthermore, even during a file system check following a sudden power loss, none of them will find silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the constant checksum monitoring makes a time-consuming file system check unnecessary.
