Hello,

 

I'm currently considering setting up a small "below the radar" Bacula
installation.

I happen to have NetApp NearStore VTLs with capacity on them, that I can use
as my back-end.

 

VTL is a virtual tape library, i.e a collection of disk that presents itself
on a FibreChannel port as being a regular tape library.

 

These VTLs are connected to a physical tape library. The backup application
doesn't see the physical tape library directly.

The way it works is that I will define virtual libraries on the VTL, define
drives and slots, and assign to a server. This server thinks he's talking to
a regular tape library; mounts/reads/writes like always.

The magic happens when the application or OS issues an "EJECT" command to
move a tape (it doesn't know it's a virtual tape) to the I/O slot. The VTL
then "fakes" such an eject and goes to work mounting a corresponding
physical tape and copies the data from disk(on VTL) on to this physical
tape. 

Works great with Veritas NetBackup.

 

My question is about the media ejects in Bacula. 

Is there such a thing?

How can it be scripted or requested? Using the bconsole utility? A
combination with MT or MTX?

 

Any ideas appreciated.
