Rclone to 2 locations (newbie :) )


I discovered Rclone today and read some of the doc but I may be missing something.
Here is what I am trying to do:

  1. Backup daily, weekly, monthly copies of my Digital Ocean Ubuntu droplets.
  2. I don’t want the sync to overwrite my previously backed up files, maybe create a new directory with time and date.
  3. Create 2 destinations: 1 Backblaze (or another Ubuntu remote server) and 1 a synology NAS which IP may change.
  4. I want to delete backups older than 15 days.

Is there an example somewhere that can use or can someone point me to the right direction?

I am thinking of full backups at this point but any strategy is welcome.
