reattach ejected USB drive

I'm using the "Eject after job completion" option with HBS 3.
Time and again I find myself trotting to the NAS, unplugging and replugging the external USB disk after a backup run because I still need it connected but the job has already ejected it.
Is there a way to reattach a USB drive that has been ejected but is still physically connected, without physically disconnecting and reconnecting it?

Not that I know of but if you don't want it ejected you could stop using that option in the job.

Sure, but in most cases I do want it ejected.
The cases where I don't are just frequent enough to be annoying.

Another possibility would be to disable that option temporarily in those cases before starting the backup.
Alas, this is prevented by HBS's peculiarity of hiding that option when the corresponding disk is not connected.
(Which is an extremely stupid design decision for many more reasons than just this one.)

If you have two jobs with that option as the only difference it would be very simple to select the behaviour you want. I'm not sure if HBS will allow two jobs with the same source and destination but it's worth a try I think.

Creating the second job fails because the destination folder already exists.

Yes of course with a backup that's expected (it may work with a sync job but that doesn't help you). i'm sorry, no more ideas.

With HSB2 I had this working perfectly. Always before the back-up / sync I did a schedule restart of the NAS (Power settings) and it recognized the USB drive.
Then when it ended it got ejected.
In HSB3 I can't click the "eject" option.

I'm guessing now but you probably need to map the disk in the job configuration to later be able to select to eject it. Do you map the external disk, not just select it?

"Eject" does not work for sync or back-up with a schedule. Odd but when using different criteria, it is an active option. Solved it now, to be tested however with my requirements.

Just to wrap up my original question: yes, there is a way.
Logging in to the NAS via ssh and entering the commands:

Code: Select all

echo 0 > /sys/bus/usb/devices/2-1/authorized
echo 1 > /sys/bus/usb/devices/2-1/authorized
makes the "ejected" USB drive reappear just as if it had been unplugged and replugged, including the start of an Auto-Backup job that has been defined for that disk, if any.

Incidentally, this means that an "ejected" USB backup disk is not safe from crypto trojans.
So always disconnect your backup disk physically after running a backup!
