Data corruption is the accidental change of a file or the loss of information that usually occurs during reading or writing. The reason can be hardware or software failure, and as a consequence, a file can become partially or completely corrupted, so it'll no longer function as it should as its bits will be scrambled or lost. An image file, for instance, will no longer present an accurate image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. In the event that such an issue occurs and it isn't noticed by the system or by an administrator, the data will become corrupted silently and when this happens on a disk drive which is a part of a RAID array where the info is synced between various drives, the corrupted file will be duplicated on all other drives and the harm will become long term. A number of frequently used file systems either don't offer real-time checks or don't have good ones which can detect a problem before the damage is done, so silent data corruption is a common matter on hosting servers where substantial amounts of data are stored.
No Data Corruption & Data Integrity in Cloud Website Hosting
If you host your websites in a cloud website hosting account with our firm, you do not need to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform works with the advanced ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. All of the info that you upload will be saved in a RAID i.e. simultaneously on many NVMes. All file systems synchronize the files between the different drives using this kind of a setup, but there's no real guarantee that a file won't get corrupted. This can occur during the writing process on any drive and after that a bad copy can be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all drives instantly and if a corrupted file is discovered, it's swapped with a good copy with the correct checksum from some other drive. That way, your data will stay intact no matter what, even if a whole drive fails.
