Hello all. I’m getting my first Amanda server running on Centos 7 and
have a few questions:
- Centos is packaged with 3.3.3 Is that good enough or should I build 3.5?
Provided it's not missing any features you need and doesn't have any
bugs that affect you, yeah it should be fine (and assuming of course
you're not exposing it to the internet). This applies even if you've
got other versions on the network too (provided the protocols match up,
it's perfectly possible to run differing versions of Amanda throughout
the network).
- the server will use only disks, no tapes. 10TB, mostly all devoted
to /home (though I could repartition)
- I believe I still use vtapes and a holding disk, even though they’ll
all just be directories on the main partition. sound right?
Yes. The holding disk is actually pretty important even when using
vtapes for two reasons:
1. It allows you to back-up DLE's that are larger than the size you've
specified for your vtapes.
2. It lets you run multiple backups in parallel without having to jump
through hoops to allow Amanda to write to multiple vtapes in parallel.
One quick tip regarding this type of configuration: Try to match the
part-size tapetype option and the chunksize option for the holding disk.
As stupid as it sounds, matching these actually improves performance
by a measurable amount in most cases. If you've got a bunch of big
backups, 1GB is generally a reasonable size for both.
- I follow the instructions at
https://wiki.zmanda.com/index.php/GSWA/Build_a_Basic_Configuration but
when running amcheck get the error:
can not stat /var/lib/Amanda/gnutar-lists
- indeed there is no file present there. any ideas?
Just create it and set the correct permissions. Strictly speaking, the
package should create this when installed, but it seems a number of
distributions' packages don't do so.
