BackupPC 2.1.2-6 on Debian Etch(stable)

[Brendan Simon <Brendan@BrendanSimon.com>]

I am currently running BackupPC 2.1.1-2sarge2 on Debian Sarge (oldstable).

I want to upgrade the backup server to Etch (stable) which has BackupPC 
2.1.2-6.  Are there any known gotchas in upgrading from from 2.1.1 to 
2.1.2 ???

I also see that BackupPC has released 2.1.3 and also 3.0.0.

2.1.3 is a bug fix release and should be available in proposed-updates 
or debian-security, right?

Eventually I'd like to use BackupPC 3.x.y on Etch (stable).
Has anyone installed 3.0.0 from Lenny (testing) on a Etch (stable) system?

Thanks, Brendan.
