Linux - Ubuntu 13.10 (saucy), 64bit, 3.11.0-19-generic, Memory 7985 MiB
AMD Athlon(tm) II X4 645 Processor, 4 CPU's
I want to periodically backup my mbr, including the partition table.
My kubuntu drive:
/dev/sdb1: UUID="5d21ae8f-80f2-46e2-8d3c-c4d1e6f71565" TYPE="ext4"
/dev/sdb3: UUID="b37c8528-ecdb-4c73-bb87-26280fad5127" TYPE="swap"
/dev/sdb5: UUID="928d11a4-eb4d-44e3-a4a0-94dd897be7d5" TYPE="ext2"

According to http://psychocats.net – backup mbr & partition Table:

sudo dd if=/dev/sdb of=mbr.bin bs=512 count=1 
[sudo] password for bumpy: 
1+0 records in
1+0 records out
512 bytes (512 B) copied, 0.0006847 s, 748 kB/s

When operating as 'user', whether from a GUI application or the terminal, you are in your user /home directory. Without explicitly specifying the location of an output operation, the output will be performed/written to your user /home directory, which is what kubicle is saying.

Technically, when an output path of an output file is not given, the output goes to $PWD which commonly is $HOME ("~" is a shortcut for $HOME) if you haven't changed directories with cd. if you run the command from another directory, the output file is put there instead of $HOME (because then $PWD is not the same as $HOME).
