Additional Copy on tape or external media


I’m starting with urbackup and so I have some questions.
At the beginning of the scenario I was planning:
1x a week incremental backup of the entire disk (the amount of storage 4), and every 4 weeks a full copy of the disk (the amount stored 2)
2x daily incremental backup of files (storage 6) 1x daily full copy (storage of 5)
Now the question of whether full copies can be transferred to an external hdd or tape drive, and what would be the option of recovering data or restoring a computer from the image and from the above copy, eg before 3 months
