An empty DB backup should raise an error [#1662796]

I noticed earlier today that I was no longer able to clone sites on my remote server. After some further investigation, I determined the real problem was that the backup task which is run as part of the migrate, was generating an empty database.sql file. I then tried to run tha backup on its own, and discovered the same thing was happening.

I've attached the output of running the provision-backup command.

from the output, rsync is saying the database.sql file being generated is 0 size.

If someone can point me in the right direction in regards to the commands that are running, I can try to get the actual output of the backup command to see why it's spitting out an empty databse dump.

I don't know if it helps, but an empty database.sql was reported with the DEFINER problems - http://drupal.org/node/1324466#comment-5634106

I wasn't using the Ubercart module, and the database dump in-fact works when called on the remote server.

Further examination showed that the issue may have been caused by my server thinking that my aegir instance has changed hostnames (it hasn't) so the mysql users might have the wrong hosts. This probably isn't an aegir bug, but rather some other issue.

However, an issue does still remain in that the backup task was reporting success when it was in fact generating backups that would not be able to be restored due to the empty database file - whatever the reason it occured, that should be raising and error of some kind probably.
