Hi Paddy,

Is ther anyway to get the next night backup to start on the tape where it finished the previous night? In other words, sometimes a backup only uses 6GB of the 20GB (DDS-4) tape. The next night it moves to a new tape in the magazine.

My configuration information:
2.5.0p2
amanada.conf:
<snip>
dumpcycle 7 days
runspercycle 5 days
tapecycle 30 tapes
label_new_tapes "daily1%%"
bumpsize 20 Mb
bumpdays 1
bumpmult 4
etimeout 300
runtapes 3
tpchanger "chg-zd-mtx"
<snip>

Here is part of report from Saturday:
USAGE BY TAPE:
Label Time Size % Nb Nc
daily101 1:31 15795776k 90.7 16 0
daily102 1:32 20155680k 115.7 4 0
daily103 0:39 6001088k 34.4 1 0
If I can't force the next backup to start on daily103 where it left off, do you have any suggestions on how to better manage the tape utilization?

Thank you,
Steve

Steve,

Amanda does not append to tapes. See http://wiki.zmanda.com/index.php/Why_does_Amanda_not_append_to_a_tape%3F
for reasons why this is not permitted.
