I'm running Amanda 3.4.5 on Ubuntu LTS Server 14.04 with an Overland NeoSeries 48 slot library with
two LTO7 drives.
I have near 100TB of external drives in various mdadm raid configurations with LVM managing the
storage and about 110 DLEs in my disklist.
One of the groups using the storage on this server has about 11TB of data representing more than 4
years of work by a group of people. It would be a real disaster to lose it, and they want an extra
set of tapes as an archive.
It seems pretty clear that amvault will do this. However, I'm trying to figure out the best way to
configure it and get it done. If I set up a storage and label some archive types to belong to that,
then I can get amvault to copy the latest fulls of a set of DLEs that correspond to their work from
the regular backups to the archive tapes. I don't see any specific examples that show how to do that
in detail (specifying particular DLEs); but, I'm also concerned that it would tie up two tapes
drives (from and to), require me to load the appropriate tapes whenever it needed them, and probably
take long enough that it would get in the way of the regular backups. I'm thinking it is likely to
work like amrecover, where it tells me what tapes it needs and then I do `amtape -o
storage="research" daily slot 7` (after looking at tapelist and changer status to figure out the slot).
Is there some other way of configuring or doing this that is more efficient? Or that would only tie
up one drive? I haven't done this yet. I'm just beginning to dig into it. Amanda 3.4.5 has amvault,
but is it missing anything that would be gained by upgrading to, say, 3.5.1?
Note that I do have holding disk space, but it is not excessively large in terms of what I am
normally backing up or want to do for this archive job. It is made up of two 4TB SSDs. I could
perhaps add some more holding disk by carving it out of LVM, but that would probably be slower with
respect to the speed of the LTO7s.
Is there any good documentation online beyond the man pages for the amvault and storage features?
With examples?
