Data corruption is the accidental transformation of a file or the loss of info which often occurs during reading or writing. The reason could be hardware or software failure, and as a consequence, a file could become partially or entirely corrupted, so it'll no longer work correctly since its bits will be scrambled or missing. An image file, for instance, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When this kind of a problem appears and it is not found by the system or by an administrator, the data will be corrupted silently and when this happens on a drive which is a part of a RAID array where the information is synced between different drives, the corrupted file shall be duplicated on all other drives and the damage will be long term. Many popular file systems either don't have real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a very common matter on hosting servers where large amounts of data are kept.
No Data Corruption & Data Integrity in Cloud Hosting
If you host your websites in a cloud hosting account with our company, you will not need to worry about any of your data ever getting corrupted. We can ensure that because our cloud hosting platform uses the revolutionary ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. All of the data that you upload will be kept in a RAID i.e. simultaneously on numerous SSDs. All file systems synchronize the files between the separate drives using this kind of a setup, but there is no real guarantee that a file will not be corrupted. This may occur at the time of the writing process on each drive and afterwards a corrupted copy may be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all the drives right away and in case a corrupted file is located, it is replaced with a good copy with the correct checksum from another drive. In this way, your info will remain undamaged no matter what, even if an entire drive fails.
