Data corruption is the accidental change of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software malfunction, and due to this fact, a file can become partially or fully corrupted, so it will no longer work properly as its bits shall be scrambled or lacking. An image file, for instance, will no longer present an accurate image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In the event that this kind of a problem appears and it isn't identified by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that's a part of a RAID array where the information is synchronized between various drives, the corrupted file shall be copied on all of the other drives and the harm will be long term. Numerous commonly used file systems either do not have real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a common problem on internet hosting servers where substantial volumes of data are kept.
No Data Corruption & Data Integrity in Hosting
In case you host your websites in a hosting account from our company, you do not have to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform employs the revolutionary ZFS file system. The aforementioned is the only file system that works with checksums, or unique digital fingerprints, for every single file. All of the info that you upload will be stored in a RAID i.e. simultaneously on many SSD drives. All file systems synchronize the files between the separate drives with this type of a setup, but there is no real warranty that a file won't be corrupted. This may occur at the time of the writing process on any drive and after that a corrupted copy can be copied on all other drives. What is different on our platform is that ZFS examines the checksums of all files on all drives live and when a corrupted file is located, it is swapped with a good copy with the correct checksum from another drive. That way, your data will stay unharmed no matter what, even if a whole drive fails.
