[Box Backup] The backup daemon on server reported an unknown error (backup-ok).

[Steve]

I've started using boxbackup - and have configured it to backup my home 
directory... about 14-15GB.  It took about 20 hours (bbstored seeming to 
take most resources) and - then with a reassuring 14764mb in the backup 
directory... I get this cryptic email:

The backup daemon on server reported an unknown error (backup-ok).

FILES MAY NOT BE BACKED UP

Please check the logs on server.

If the backup really is OK, then that shouldn't be an error... IMHO... 
but I checked the logs - just in case.

I don't see any errors reported in the log... Which makes me wonder - is 
this email evidence of a bug, or is it a glitch with my configuration?

I'm using the default packages for boxbackup-client and boxbackup-server 
on Ubuntu Server 10.10.  The executables report:

Box Backup Store Server v0.11rc2+2502, (c) Ben Summers and contributors 
2003-2008
Box Backup Client v0.11rc2+2502, (c) Ben Summers and contributors 2003-2008

I re-created my configuration from scratch... because I want continuous 
backup, as opposed to a snapshot approach.
