[Help] TOS-6 Duple Missing RSYNC

[mcchico]

Equipment: F4 SSD
Background: I want to backup TNAS to an older Buffalo Linkstation.
First option: I configured Rsync Backup in TNAS to backup shared folders and worked perfect
Issue: Rsync Backup does not have the option to delete files at destination

I did a Goggle search (and also in Forum) many places it mentions to use Duple with Rsync -- However, and apparently there was an option to select Rsync before but when I try to configure Duple in TNAS I only get options to backup to TNAS (local/remote) or CLOUD. There is no Rsync option.
Therefore, if I want to backup shared folders using rsync and deleting files in destination - what will be the solution?
Thank you.
