Sure, I can see this being important, but in this case, I'd probably
just write a custom perlfind script to capture the data and store it,
then have bacula save that script and metadata file. Seems simpler,
and makes your life easier, since you're now not tweaking bacula to do
something it's not meant to do.
Also, part of the metadata you'd like to keep is where you got the
file(s) from if at all possible. Which Bacula won't be able to do
unless you keep that info a master file somewhere and have bacula do
the backup of that file.

If you think you need to handle ACLs, that's going to make this a
harder problem, and you'll need to look into the access() function and
maybe read up on how other backup programs handle ACLs cleanly. It's
not a simple thing to get right, and will almost certainly require
root privs (on Unix like systems) to even run properly.

Andre> File = "/"
Andre> File = "/boot"
Andre> JustMetadata = "/data"

Andre> I guess that's not possible, is there an equivalent way in funcionatily?
