Regarding my recent post regarding "strategy incronly" and "skip-full",
I just found out more about the problems I've had in the past with this
simply by checking the amanda.conf manual page it says:
skip-full /boolean/
Default: no. If true and planner has scheduled a full backup,
these disks will be skipped, and full backups should be run
off-line on these days. It was reported that Amanda only
schedules level 1 incrementals in this configuration; this is
probably a bug.
and also
strategy {standard|nofull|noinc|skip|incronly}
[ ... ]
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.
So, the problem with setting up an incremental-only config is that with
"skip-full", incremental level will never be increased above 1, while
with "strategy incronly", it is updated correctly, but the level 0s
(scheduled via "amadmin force") won't be skipped correctly. Or at least,
that's the way it's been in the past. Does anyone know if anything has
been done lately to address these issues?
