Backup fails with "failed to TAR up repositories"

I'm on Virtualmin 4.06 Pro and when the scheduled backup runs it chokes on a specific virtual server with:

Backing up Git repositories and configuration files ..
.. failed to TAR up repositories : 

This virtual server does have the git feature enabled and it's not currently practical to remove it.

Any ideas why it might be failing? Is there a more detailed backup log I can look at?

Running a manual tar across the git directory completes fine.

I see other people have the issue on the forum but there' no resolution listed.

Kind Regards,

Alex

Are your git repositories stored in a git directory under the domain's home dir?

Having checked it looks like the git repository that existed has been removed, is the fact the feature is enabled but there's no git repository available causing the error?

I think I've got git enabled on other servers without any repositories configured that I don't get the backiup error on.

Ok, so for the problem domain, is the git directory completely empty?

Have pulled feature off and that's cleared the error, not getting this on other virtual servers that have git enabled so assume it's an oddity with that server.
