Why is Norton 360 Backup so slow, I can backup all my files to external SSID in less than 10 minutes

I would sooner do my own backups but I keep getting warning messages to Backup which I cannot over ride at the moment.

Wish I could just cancel out Backup altogether. I have 4 External drives. Currently using WIN 11 PRO with I-7 Processor 16 mb ram

and SSID and Norton 360 Ultimate.
