Assuming you are using bash, and you have files on your local machine that
start with "backup" I think the scp will complete the files based on the
named in your local directory.

If the local directory was empty, and then you tried the above like this:
$ scp p@remote.host:backup* .
The results would not like be the same as when you found them to work.
(They only "work" because of the files in your local dir.)

To use the "*" on remote machines, try escaping it:
$ scp p@remote.host:backup\* .
(This should work even when you do it from a locally empy dir.)

This works. On the remote machine, the * is applied as a wild card.

It should, and I expect it to fail if you do not have files in the local
machine's dir that start with "backup"
