Matteo,
Before messing with this stuff, get Amanda running in two standard
configurations (one for each tape drive).
After that I'd have a look at the man page for the strategy parameter.
strategy "string"
Default: standard. Strategy to use when planning
what level of backup to run next. Values are:
standard
The standard Amanda schedule.
nofull Never do full backups, only level 1 incre
mentals.
noinc Never do incremental backups, only full
dumps.
skip Never do backups (useful when sharing the
disklist file).
incronly
Only do incremental dumps. `amadmin force'
should be used to tell Amanda that a full
dump has been performed off-line, so that it
resets to level 1. It is similar to skip-
full, but with incronly full dumps may be
scheduled manually. Unfortunately, it
appears that Amanda will perform full
backups with this configuration, which is
probably a bug.
The developers will tell you if the "incronly" bug still
exists. Another bug: Is there a parameter strategy "skip-full"? The
trick is to use "strategy incrony" for the small tape and have the
full backups started by an external skript.
OTOH is it worth it to reuse old DDS2 tapes over and over? I'd make
restore tests as soon as possible and tell the boss that DDS tapes can
be used only about 10-20 times before they get unreliable.
HTH,
Johannes Nieß
