I have one folder with about 20 GB that I am encrypting. I have set TM to ignore this folder, and am using the Espionage backups.

Unfortunately, each TM backup is now on the order of 30 to 40 GB, where they were under 1 GB before.

Is there something I need to change? Is each backup a single file, that with a single change gets backed up in entirety?

I will run out of storage space in a week with this sort of issue.

Thanks!
