Hi all,
Now that everything appears to be working, I'm getting ambitious
(possibly stupid).
For context, I'm backing up a small network to DVD-R sized vtapes that I
then burn to DVD-R.
Oh, did I mention that I'm somewhat paranoid? :-) I know that DVD-R,
especially the cheap media that I buy, isn't the most reliable in the
world. I get initial losses (burns don't verify) of about 10%. Then I
look at RAIT, the additional 20% media I'd need for a 5-tape RAIT seems
like a nifty idea to increase the reliability.
I tried setting up a simple chg-rait that was based on 5 chg-disk
changers and it merrily blew up in my face.
First make 5 (rait-number) directory trees containing as many vtapes
are you have in tapecycle:
$ mkdir -p /amanda/set{1,2,3,4,5}/vtape{1,2,3,4,5,6,7,8,9,10}/data
Then use chg-multi with entries like:
slot 1 rait:/amanda/set{1,2,3,4,5}/vtape1
slot 2 rait:/amanda/set{1,2,3,4,5}/vtape2
slot 3 rait:/amanda/set{1,2,3,4,5}/vtape3
etc.
slot 10 rait:/amanda/set{1,2,3,4,5}/vtape10
I'd love to have 5 chg-disk changers being run by a chg-rait so that I
end up with 5 DVD-R images / tape.
I like to know to how a combination of chg-disk with chg-rait is configured.
