Hi again
If I run a Monthly config
#'sudo -u amanda crontab -e
# Backup check running amcheck at 4.30pm on the 2nd day of each and
every month.
30 16 2 1-12 * /usr/sbin/amcheck MonthlySet1
Thus use 12 DSS-4 DAT Tapes and set the Monthly amanda.conf as below
dumpcycle 4 weeks # the number of days in the normal dump cycle
runspercycle 1 # One run per month
tapecycle 12 tapes # the number of tapes in rotation 12 per Year.
Would these be better
