Hi there,
This question might be answered somewhere but I didn’t find
the proper source to find it out. I want to split Quantum i3
library with two differen virtual libraries with two
different size tape drives LTO6 and LTO8 so I can run
incremental and full backups in the same library.
Has anyone done that and is there any downside/upside on
doing this?
I do run a kind of similar setup, but the different LTO generation
drives are used for backup up different clients.
Hardware is an Overland NEO2000 library, one LTO2 drive and one LTO5
drive. They show up in the linux machine attached as three individual
devices (1 changer, 2 drives). From here, the Bacula setup is quite
straight forward:
- assign the LTO tapes to (at least) one pool per LTO generation
- assign the pools to the job definition(s) via the "Full Backup Pool",
"Differential Backup Pool" and "Incremental Backup Pool" directives
- Link the pools to the storage ressources via corresponding "Media
Type" directives
- include both device ressources in the Autochanger configuration
block of the storage daemon
At least for me *no* creation of split virtual libraries was necessary,
but that may vary with your hardware.
HTH,
Sebastian
