Use the select qualifier
$ BACKUP abs$MKB600:Wabs$DKD500.BAK/SAVE/SELECT=(aaa.ccc)
[]

would find files matching aaa.ccc in any directory and restore them to your current default directory.

If you're restoring to a directory that isn't owned by the account that's doing the restore, I'd suggest /by=original on that as well. If you don't do that, it'll try to make the file with the ownership of the account running backup, and it might not let you create the file.

Also, if you have more than one saveset on the tape and the file you want isn't in the firet one on the tape, specifiy the saveset name so it will skip to the one you want rather than reading through every saveset.

Atul,

To begin with:
WELCOME to the VMS Forum!

Good answers were given so far.

Let me extend a bit on them:

For the /SELECT=
you can also use directory specs,
and, you can also use wildcards.

An example:
/SELECT=[TOPDIR.SUBDIR.PART*...]AB*.DAT

would select all files with names starting AB amd filetype .DAT in any directory PART* in [topdir.subdir], and in all its subdirectories.

In general, it is preferable if the ... subdirectories wildcard is used, to also specify an output directory [PUT.IT.HERE...]

That way, the directory structure down from .PART* in the example is reconstructed in PUT.IT.HERE, giving [PUT.IT.HERE.PART...]

If you do not know the exact directory structure of filenames, you can first create a listing with
$ BACKUP/LIST= abs$MKB600:wabs$dkd500.bak/sav

hth

Proost.

Have one on me.
