Backup ALL local shares to USB drive

I have a RN316 currently on Firmware 6.1.4.
Using these settings I’ve been able to successfully backup the /data volume using a Rsync backup to a USB disk (USB_HDD_1) via the Dashboard (Backup tab) and exclude the snapshot data:

0. “Add Backup”
Name: <your choice>
Source: volume: data
Destination: remote: Rsync Server
Select ‘Create’

Note: “share: USB_HDD_1” couldn’t be used for Destination - it was an available selection, but “Destination” turned red when I selected ‘Create’

1. Source tab
Type: volume
Name: volume: data

2. Destination tab
Type: remote
Name: remote: Rsync Server
Host: localhost
Path: USB_HDD_1/backup/RN316Store

Note: the backup creates a folder named ‘data’ under USB_HDD_1/backup/RN316Store
Note2: select ‘Test Connection’ - results in an Info pop-up with:
“Successfully connected to localhost::USB_HDD_1/backup/RN316Store”

3. Advanced tab
Remove deleted files on source - is checked
FILES & FOLDERS TO BE EXCLUDED:
- Select the ‘+’, enter the following in the “Name:” text box, select ‘Apply’:
/data/._share

Note: this prevents the snapshot data from being copied (i.e. /data/._share)

4. Schedule tab & Options tab - your choice
