I would like to add an additional level of authentication to AMANDA. I really don't want to setup kerberos, but want something to keep someone from hacking into one of our internal machines, taking over the amanda servers IP and backing up one of the other machines. Also, I want it to be simple to setup. I know it is a longshot that it would ever happen, but that is what I have been asked to protect us from.

Hi There,
I plan to change amanda backup schedule due to reduction of the size of the

Here is the list of changes I think I should do.
1. amanda.conf
dumpcycle 30 days
runspercycle 15
tapecycle 16 # (15+1)
### Do I need to change this? The backup disk has 200G, that's why the length

hold a full dump. Since this is vertual tape, I can probably set to 30G and
hope there will be no more than 6 full dump per cycle.

2. chg-multi (tapechanger)

slot 16 file: /xxx
3. Add tape directories T5-T16 on backup disk.
4. cron

My questions are:
1. Do I miss anything I should change?
2. When will this change take effect?
3. Will amanda do this transition seamlessly?
Depending on where you are in using your tapecycle, it may not
start immediately with the new vtape in slot 5.
Unlikely there will be 6 full dumps of anything in a month
as you have only asked for 'at least 1' a month. But you
won't know until you've tried. I suspect leaving the tape
size large is not going to be a problem. Monitor the disk
usage for a while to be certain.
I'd be scared with only 1 tape more than the minimum.
Suppose something is 'off-line' the day it is due for
a full backup. On the next amdump run, the tape containing
your only full dump will be overwritten. Consider the
possibility that the DLE is still off-line or an error occurs.
You will have no full dump for that DLE. Now you have only
incrementals. I'd feel better with 32 tapes or 14 day dumpcycle.

Re: slightly more secure...
Nods to those smarter than I am, but if that is your specific concern you might do better to just set up arpwatch. It pairs up ipaddresses with the mac address of the card in each machine on your network. After set up it will monitor the network and can email/page you if a different mac address pops up with a different ip address.
