dual tape drives, 1 changer, two configs
2006-09-11 12:22:34
I have a dual tape drive capable auto-changer that I was planning to add
a second drive to in order to increase throughput and thereby decrease
the backup window. But, from reading through the docs and previous posts
to this list, it would appear that Amanda will not natively write to
both drives at the same time without resorting to using a two config
model. I have a few questions about the 2 config model.
- I have a 14 slot array. Can I have the two configs share the same
tapelist? So that I don't have to split up the slots into to groups of
7 with separate tapelists and potentially have the tape swapping days
become out of sync. (ie, group 1 takes 2 tapes on night, so 6 days into
it, it needs to they need to be swapped out, but group 2 still has an
open tape to use). I'd like to continue to swap all 14 tapes at the
same time.
- Most of the posts regarding configuring Amanda to write to both tape
drives simultaneously are at least a year old. Does the 2.5.x version
address/fix this limitation? or are there any future plans to add this?
- Any examples out there of best practices, or sample configs, for the
two config model? (anyone willing to share theirs?)
Thanks
