I just setup the offboard backup a few days ago, but I'm already realizing that the drive is going to fill up quickly with backups. In another post, I saw that it is okay to manually delete the files. I see that there are base and incremental backup files. Before I just start deleting things, I want to make sure that the incremental backups include everything since the last base, so I only have to keep the last base and last incremental backups.
Also, how often are the base backups created?

So yes, every incremental contains the changes since the last base backup (and yes, it is a differential not an incremental backup)
the Base contains all files which rarely change and the incremental all regulary changing files.
The base is created once a week
