Guys, so I have SSH enabled now. Is this Rsync with -c option something I can run directly from the NAS using Putty (comparing NAS data versus data on a USB-connected HardDrive) ? If yes:
1) what are the exact commands to run for my setup? Here is one set of folders I would want to compare:
NAS:

USB Harddrive:
NAS volume name: USB_HDD_3
Folder: /backups/Data01
2) would running this -c Rsync process produce an output of differences ? or will the Rsync process just copy (from the USB to the NAS) when differences are detected?
