Mount USB Drive

Warning

The Duplcati backup service auto-mounts compatible drives. Data corruption will occur if the same drive is accessed from several services simultaneously.

Find Device Name

Plug the drive into an available USB port. Then run

sudo fdisk -l 

and take note of the device name, e.g. /dev/sdb1.

Mount Device

sudo mount  -t exfat -o rw /dev/sdb1 /mnt

Replace the device type (exfat) with the appropriate value for your drive and substitute the device name obtained in the previous step. /mnt is the directory under which the contents of the drive will be available. You can specify a different value, but the directory must exist.

Copy Contents

To copy contents from one drive (or location) to another, use rsync. E.g.

rsync -au --progress --exclude=".*" /src/ /dst/

where /src/ (e.g. /mnt/) and /dst/ are the source and destination directories. If rsync is interrupted or the contents on /src/, run rsync again to make /dst/ an exact copy of /src/.

The optional --exclude=".*" excludes all files starting with a dot. Use the --dry-run flag to only see the actions to be performed without actually making any changes.
