Data corruption is the unintended modification of a file or the losing of info that usually occurs during reading or writing. The reason may be hardware or software malfunction, and as a result, a file may become partially or entirely corrupted, so it will no longer function as it should because its bits shall be scrambled or lost. An image file, for example, will no longer show an accurate image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. When this kind of a problem occurs and it's not noticed by the system or by an administrator, the data will be corrupted silently and when this happens on a disk drive that is part of a RAID array where the info is synchronized between various different drives, the corrupted file will be duplicated on all the other drives and the harm will be permanent. Many widely used file systems either do not have real-time checks or don't have high quality ones which will detect an issue before the damage is done, so silent data corruption is a rather common matter on web hosting servers where huge amounts of information are stored.
No Data Corruption & Data Integrity in Website Hosting
If you host your Internet sites in a website hosting account with our firm, you won't have to worry about any of your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform works with the leading-edge ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any info that you upload will be kept in a RAID i.e. simultaneously on a large number of SSD drives. Many file systems synchronize the files between the separate drives with this kind of a setup, but there's no real warranty that a file won't get corrupted. This can occur at the time of the writing process on each drive and then a damaged copy can be copied on the other drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all of the drives immediately and in the event that a corrupted file is identified, it is replaced with a good copy with the correct checksum from some other drive. That way, your information will continue to be unharmed no matter what, even if an entire drive fails.
