Rsync Local (from share to 2 external USB drive)

Hi All,

I've a Raid 1 (2 x 4TB) and 2 USB EXTERNAL Drive (4TB).

I would like to use 1 Ubs external Drive a week (1 connected for all week in office, and 1 not used at home for safe).

I've configured 2 different Rsync Job (1 @ 10am and 1 @ 9.45am) to backup my shared folder on external drive.

When I unplug External Drive 1 and plug External Drive 2 I need to mount filesystem manually (if I don't manually moud Rsync did't find destination)

Any suggestion to solve my problem?

Many thanks.

Bye.

I need to take USB HDD always connected to NAS for one week, I switched from UBS Backup to Rsync to bypass this problem.
