Brian, one way to achieve this is to move your clearcase server to an
OpenVz container. With OpenVz you will be able to use rsync. with
'checkpointing' (freezing) to get a valid backup.
it works like this
- rsync container(vm) with remote machine
- checkpoint
- rsync again (will now be very quick)
- un-checkpoint
- tar on remote server
read about checkpointing here -

there's a pre-made script to do all this -

By moving to OpenVZ you will also gain other advantages such as live
migration, ability to quickly re-start your backup (also useful if you
need a playground), painless migration to a DRBD clustered environment.

However im not sure of the does and donts of using rsyn on open files, and also due to the fact the largest files (70Gb) would probably have changed during its own rsync.
