I guess "Time Machine" is something Apple-like, and I don't know nothing
about it but the name. But if what you told is the essential, that is the
disk usage strategy, it shouldn't be a problem though minor differences
might exist.
I didn't notice "Volume Retention" specified in your Pool config. I controls
how soon after the last write the volumes can be recycled. Since you make
full backup once a month, this should be set to the minimum of more than one
month (eg. 40 days) to make sure you'll always have at least one (I'd
seriously recommend more, at least two) full backup(s) available. After this
period, if necessary, Bacula _can_ recycle the existing volumes. However,
actual recycle won't happen until really needed to free the previously used
volumes, but it can't happen before this time limit has expired.
Also remember that modifying the pool parameters in the conf does not
automatically apply to the existing volumes, only to the new ones created
thereafter. To make the existing volumes to obey the new values, you'll need
to use the update pool / update volumes from pool commands from the bacula
console.
Regards,
Timo
