Thanks for this as it is exactly what I want to do too (except the annual
full BUP)
I am a little confused about setting up the jobs. If there are 2 jobs per
client, how do they write tothe pools full1, incr1, full2 and incr2? I have
all mine set to level = incremental and when there is a new volume, Bacula
automatically upgrades it to a full but to the same (default) pool.
Would you explain a little more for me, please?
What do I do with the catalog? Does this remain as it is, i.e. just one
catalog for all the jobs and all the pools, do I use one of the new ones
(full1, etc), or do I keep the default pool?
TIA
