Editing Backup (section)

===Metadata===
Not all information stored on the computer is stored in files. Accurately recovering a complete system from scratch requires keeping track of this [[metadata|non-file data]] too.<ref name="Gresovnik1">{{cite web |url=http://www2.arnes.si/~ljc3m2/igor/blogs/technical/bootable_media_creation.html |title=Preparation of Bootable Media and Images |last=Grešovnik |first=Igor |date=April 2016 |archive-url=https://web.archive.org/web/20160425113119/http://www2.arnes.si/~ljc3m2/igor/blogs/technical/bootable_media_creation.html |archive-date=25 April 2016 |access-date=21 April 2016}}</ref>
*System description: System specifications are needed to procure an exact replacement after a disaster.
*[[Boot sector]]: The boot sector can sometimes be recreated more easily than saving it. It usually isn't a normal file and the system won't boot without it.
*[[Disk partitioning|Partition]] layout: The layout of the original disk, as well as partition tables and filesystem settings, is needed to properly recreate the original system.
*File [[metadata]]: Each file's permissions, owner, group, ACLs, and any other metadata need to be backed up for a restore to properly recreate the original environment.
*System metadata: Different operating systems have different ways of storing configuration information. [[Microsoft Windows]] keeps a [[Windows Registry|registry]] of system information that is more difficult to restore than a typical file.
