Hi All,

Pretty new to bacula so apologies if this is dumb..I would like to
simulate a "Mac Time Machine" feature. My setup is to have a full
backup every 2 months, a differential every other month (out of sync
with the full) and an incremental every day.  I think I have this
setup as expected and it all writes to a pool.

What I'm now trying to do is setup a short term hourly pool which will
allow me to roll back upto say a day or twos work on hourly
increments.  For this I've setup a second pool that writes to a
different disk.  The question I have is when the incremental is done
on the daily basis does it look at the other pools data (which gets
refreshed after 23 hours) or the last incremental on the main backup
pool? Sorry if this is confusing - I've posted relevant sections from
the bacula-dir.conf below:

Many thanks
