Areca Backup

Example :

I have 2 targets, 1 for my personnal settings and documents on the PC, one
for my NAS (through SMB - but not relevant, could just be another local
drive or whatever reason one want to have a different target).

If I want to execute both targets, I need to launch them simultaneously,
which slows them both down a lots, or launch one, wait till it's completed,
then manually lauch the next one.

It would be great to ber able to select an arbitrary number of targets and
execute them as a queue : the first is executed, then when it's completed,
the next one is launched, etc. until they are all completed.

I guess it must be possible to do that in the command-line but I didn't
find a way using the GUI.

Anyway, thanks for the great software ;)
