Rsync and Tar

[Steve Sills]

Hello,

	I am trying to setup a backup system.  What I would like to do is have 
rsync create a tar file as it downloads (to save space) and just have it 
update that tar file.  Can rsync create a archive on the fly, or does 
this have to be done after its finished its transfer?  I would also like 
to have rsync report its transfer stat to a MYSQL database for billing 
purposes, on a per client basis.  Can this be done?

Thanks in advance

Steve
