That could work, but you have to create a backup job for each backup target you use.
I’m wondering what would happen when you use advanced option –dbpath to change the location of the local DB to the backup drive itself. Result we be that each backup drive will contain a database that is in sync with the DBLOCK/DINDEX/DLIST files on that drive.
I’ve never tried this, but I guess there could be some pitfalls:
- Performance drop could be expected. Database queries use the same bus as the backup data that is read/written from/to the external disk.
- Before starting any operation, one of the external disks must be attached. Basic operations, like displaying a list of backed up folders, need access to the local DB.
