Ready NAS 3138 Rsync Error

Model - Ready Nas 3138

Firmware - 6.9.2

Hello Everyone

Could someone please help me with this?

I have created some Rsync backups between our 2 Netgear Ready NAS devices. One backup is started to fail recently. We haven't done any changes. I really appreciate if someone can look into this. Please find the logs below.
