That's to be expected if nothing was backed up so far.

Yes.

You should not need to run bbackupd with -DVT normally, and if you do that 
in the init script it will probably never terminate.

Could you try running bbackupd with -kVT instead? It should go into the 
background but continue writing to your console. This may mess up the 
console a bit, but it will help to figure out why it's not working when 
you just run bbackupd normally in the background.

Can you have a look at the initscript to see what's wrong? I'm afraid I 
didn't write it and don't have a debian box offhand to test on. Logs in 
/var/log/messages (or /var/log/box) may help to understand the problem.

I'm afraid not, but you could guess a 2:1 compression ratio unless you 
have a lot of uncompressable binary files, in which case it's likely to be 
more like 1:1.

Nothing will crash, the client will stop uploading when it hits the limit.

I'll think about it, but probably the best option is to run a log parser 
like bbreporter.py and have that process the numbers into something more 
human-readable for you.

Which specific log messages are you referring to?

No problem, I've written it up on the wiki now as well.

Cheers, Chris.
