JSI Tip 5955. How can my scheduled Ntbackup react to my failure to insert a tape in the tape drive?

I would occasionally forget to insert a tape in my tape drive, and arrive the next morning to find that my scheduled Ntbackup is waiting for me to mount a tape.

To avoid this behavior, I first determined the GUID of my tape device, by opening a CMD prompt and typing:

rsm view /tlibrary /guiddisplay.

This returned a display that included:

HP C1537A SCSI Sequential Device C888E08900454C4C956DF84868C17C78.

If you type:

rsm view /cgC888E08900454C4C956DF84868C17C78 /TPhysical_media

you receive a display similar to:

PHYSICAL_MEDIA
2002_10_30_18_00 - 1
The command completed successfully.

where 2002_10_30_18_00 - 1 is the tape label.

Using this information, I added the following to my script, before the Ntbackup command:

:checkmedia
set media=
for /f "Tokens=*" %%a in ('rsm view /cgC888E08900454C4C956DF84868C17C78 /TPhysical_media') do (
 if not "%%a"=="The command completed successfully." set media="%%a"
)
if /i %media% EQU "Unable to open session with the RSM server." goto checkmedia
if /i %media% EQU "PHYSICAL_MEDIA" goto notape
if not defined media goto notape

At the :notape label, I emailed myself a message and aborted the scheduled backup.

NOTE: If I knew that someone was in the office, I could have also used net send.
