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