I you had to synchroize different jobs manually then this would be indeed a
kludge.
But this is not the case.
In bacual-dir.conf you can define:
#
# Define the main nightly save backup job
# By default, this job will back up to disk in C:/tmp
Job {
Name = "ABCD"
JobDefs = "DailyBackup"
Max Start Delay = 22h
ClientRunBeforeJob="script_to_mount_drive.sh"
ClientRunAfterJob="script_to_unmount_drive.sh"
}
And all your worries are gone.
Tapes sound easier but they aren't. With tapes it becomes complicated once you
need the autochanger because the amount of data to backup doesn't fit on one
tape.
