What I’m trying to do and why
Backups take a while but if you have a powerful machine, you could run them in parallel! This is possible to manage externally from borgmatic but it would also be nice to have a
-n N flag to signal some cores and have borgmatic run what it can in parallel. The user would have to make sure that what is being backed up can be done in parallel.
This is probably a can of worms but would be nice to think through.
