As others already responded, this is possible.
The best method will be to rebuild at least the media index Information (scanner -m) ... if you have time.
Then you can either …
- recover a whole save set (recover -S ssid) and get your files from here
- recover a subset (files/dirs) but you must know the exact full absolute path name like in this example:
recover -S ssid -a absolute_path_name
Other options may be necessary - please see Command Line Reference for Details.
These rules apply to normal file system backups.
NDMP (and other) backups will need special treatments.
