Wow.
Could you please re-read this, and consider whether this is really the
"simplest possible level"? I think I understand what you mean, but it's far
from "simple".
In my experience with Bacula, the most frequent request from users for restores
is something like:
I accidently removed all the "dat" files from /foo/bar. Could you
please restore them?
I've always felt that the restore menu and choices in bacula seem to be
oriented around the way bacula works (ie., supplying a list of JobIds), rather
than around the way that humans work (ie., restore all "dat" files from
/foo/bar and below, without specifying an exact list of files).

=>

=> WHERE f.FilenameId = n.FilenameId AND f.PathId = p.PathId AND n.Name
=> LIKE "%partial filename%" AND p.Path LIKE "%partial path%" ORDER BY
=> p.Path, n.Name;
=>
=> This query could also be performed as:
=>
=> SELECT DISTINCT Path, Name FROM File LEFT JOIN Path ON File.PathId =
=> Path.Pathid LEFT JOIN Filename ON File.FilenameId = Filename.FilenameId
=> WHERE Name LIKE "%partial filename%" AND Path LIKE "%partial path%"
=> ORDER BY Path, Name;
=>
I'm sure that those examples work--and are much better than my poor attempts to
write SQL to do similar queries. That'll be a big help.
However, given what a common use-case this is for any backup system, it would
be nice if the bacula restore process was more user-friendly.
Thanks,
Mark
