Re: Mounting a dump file

However mounting the file system in the dump file fails:

I was hoping to be able to mount the the dump file then restore its contents to an empty partition as a way of doing a bare metal restore of the source machine if it dies. Could someone point out where I'm going wrong please?

Don't try to mount(8) the output from dump(8) - that output is a file, and not a filesystem!

Instead, just try to use restore(8) on it:

restore -i -f tstdmp-dump-2013-04-10
