newbie: incremental vs differential
I can't wrap my head around the difference. I have a bunch of music files. I make the following kinds of changes: delete files, re-tag files, and add files. I would like to make a full backup and then shorter backups that only handle the files that have changed. But I don't want to keep the old files in the backup, otherwise I'll run out of space. In which kind of backup are the deleted and old files removed from the backup?
