Data corruption is the unintentional transformation of a file or the losing of info that usually occurs during reading or writing. The reason could be hardware or software failure, and due to this fact, a file can become partially or fully corrupted, so it will no longer function as it should as its bits will be scrambled or lacking. An image file, for instance, will no longer show an accurate image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When this kind of an issue appears and it is not identified by the system or by an admin, the data will become corrupted silently and in case 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 other drives and the damage will be long term. Numerous popular file systems either do not feature 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 common matter on web hosting servers where huge amounts of data are stored.
No Data Corruption & Data Integrity in Cloud Hosting
If you host your websites in a cloud hosting account from our company, you will not have to worry about any of your data ever getting damaged. We can ensure that because our cloud hosting platform works with the reliable ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for each file. Any kind of info that you upload will be kept in a RAID i.e. simultaneously on many different SSDs. All of the file systems synchronize the files between the different drives using this kind of a setup, but there's no real warranty that a file won't be corrupted. This may occur during the writing process on each drive and afterwards a corrupted copy can be copied on the other drives. What is different on our platform is the fact that ZFS examines the checksums of all files on all drives in real time and in case a corrupted file is discovered, it's replaced with a good copy with the correct checksum from some other drive. In this way, your info will stay intact no matter what, even if a whole drive fails.
