How a dump restore works

A dump restore writes file system data from tape to disk using a predefined process.

The process in the following table shows how the dump restore works:

StageAction
1ONTAP catalogs the files that need to be extracted from the tape.
2ONTAP creates directories and empty files.
3ONTAP reads a file from tape, writes it to disk, and sets the permissions (including ACLs) on it.
4ONTAP repeats stages 2 and 3 until all the specified files are copied from the tape.
