Backup Files

I have to backup some filesystem. But the point is that I have NOT to rewind the tape. What I see is that I can make a vdump 0uCf /dev/nrmt0h / (as an example) or make the following: vdump 0uCfN /dev/rmt0h / .
My question is which one is better to use.

Thks in Advnaced.

Re: Backup Files


I could not find any difference. I always use the norewind device.

Re: Backup Files


I'm fairly certain that the "N" argument with a rewind device causes vdump to use the No-Rewind device instead.


#vdump 0uCfN /dev/rmt0h /

Actually ends up being execute as...

#vdump 0uCf /dev/nrmt0h /

I'd advise using the device name rather than an argument to the command. It's clearer as to the intention of the command.

Hi Sebastian

I would prefer OuCfN as this wouldn't rewind the storage device.
