Backup Central

I'm doing backups of a Lotus Domino server using NTBackup. The differential backups are huge because Domino essentially touches each DB every day. I need to save space on my backup media (Terastation). I want to keep the original normal backup and the latest differential backup and delete the others. Is there a way to do this in NTBackup?

I suppose in the future the answer is to make the differential backups with a different name, but the problem with that is that it significantly complicates writing a batch file to automate the process.

Thanks.

i don't know NTbackup, but you should find a way to do some sort of Retention period, and set it that way ? Like 2 week, so you'll have the current week and the week before that, that's it.
