Requires Mount = Yes
Mount Point = /mnt/backup1
Mount Command = /sbin/mountBackup1
Unmount Command = /sbin/umount /mnt/backup1
Where /sbin/mountBackup1 is a script that reads the drive and mounts the first partition to /mnt/backup1, and if the disk doesn't have a first partition it assumes it's a clean disk and writes a partition table and creates an ext3 partition, then mounts it.
This seems to be the most straight forward way to do it and I'm a little surprised it doesn't exist already. Without it, I'm just going to create two scripts that manage the drive's mounted status and the user will have to do it manually.
I suppose the only wrikle is detecting when a new drive has been inserted. Preferably, Bacula would listen on dbus for a particular (configurable) message, and the user (again) care take care of it.
I'm pretty busy right now (and my that I mean the last few and upcoming years), but when I get a chance (hopefully later in the week) I'll grep through the Bacula source. No promises.
Thanks for the quick (albeight disappointing) answer,
John Demme

You can't achieve what you want like this.
The requires mount options and related stuff heavily depend on the write
part command program, so first, you'd need a real program that does what
dvd-handler does with DVDs - writing part files to the device, mainly.
Unless you're ready to read through the SD code - especially the parts
regarding DVD writing - and creating a customized write part command
program, what you want to do is not easily possible.
There have been some suggestions as to how effectively use removable
hard disk storage recently, you might want to search the archives for
these. Also, Kern has started thinking about how to handle removable
disks, so it might be that he comes up with something some day.
And, of course, you can always suggest how Bacula should handle this
sort of stuff, and also submit code :-)
