R5 Domino server backups using transaction logging

What backup solutions are available for an R5 Domino server using transaction logging? Does anyone other than Tivoli support this configuration?
The only other option I know of is Veritas NetBackup. This is not the same as Veritas BackupExec. It is a different backup product from the same company. It has two components, the NetBackup agent as well as a NetBackup agent for Lotus Domino. This product can backup R5 servers running transactional logging. Information on NetBackup can be found at http://www.veritas.com/us/products/netbackup/. You can contact a Veritas representative for pricing.
