want to migrate to bacula from rsync backups.

I've been backing up my network using rsync for a long time because I've 
rarely had a need to go back more than one day to retrieve a file I 
wanted. However, after my upgrade to Debian 13, that backup has stopped 
working. Rather than debug that, I figured now would be a good time to 
implement a more versatile backup.

I've used bacula in the past for some business customers, but that was 
pre-pandemic. My expertise is both dated and rusty.

My issue is, can I import my existing backup files into bacula and use 
them as the basis for future incremental backups? They are basically 
just copies of the files I want to back up, with the same directory 
structure but with a different root. My idea is to import them into 
bacula then switch the nightly backups to the original folders so new 
backups reflect the changed files only.

The reason I want to do this is the rsync backups contain files that may 
be missing from my current working folders. I don't want to lose them 
but I also don't want to reverse the rsync to restore them to their 
original locations.

Any help will be appreciated.
