If your purpose is backup - then you are *far* better mounting the disk as a
file system and then copying files somewhere using tar or cpio. That somewhere
could be a disk - although something like a USB memory stick would be better as
these are more robust and smaller than a hard disk.
Why:
• you are copying the data (your files), not all the other bytes on disk (that
are useless to you)
• the tar/cpio archive will be readable on a greater number of systems than
just the ones that support the file system on your disk (prolly ext2/similar)
