+===== backing up the BeagleBone Black eMMC =====
+After you have got the BBB up and running how you like it, backing up is always a good idea.
+You can of course back up the ini settings, plugboard scripts etc using the web GUI but I like to keep a backup of the entire eMMC.
+There are a few methods to be found on the 'net that require the use of a script on a microSD card. This is ideally the best way but requires
+stopping the BBB (and if SWMBO is expecting things to happen, that's never good)
+So here is an option to use dd over ssh to backup to another PC (in my case a mac)
+on the BBB
+<code>
+sudo dd if=/dev/mmcblk0 bs=1M | ssh themac@192.168.0.X "dd of=/Users/themac/Desktop/BBB_Backup_date.img bs=1m"
+</code>
+n.b. the block size is set on the BBB using bs=1M but on the mac HAS to be bs=1m (lowercase) (I'm not sure if this is the case :) on a pc)
+To restore. This needs to be done after booting from an SD card to free up the eMMC
+The eMMC is then mmcblk1 not mmcblk0
+<code>
+ssh themac@192.168.0.X "dd of=/Users/themac/Desktop/BBB_Backup_date.img bs=1m” | sudo dd of=/dev/mmcblk1 bs=1M
+</code>
+Then power down, remove the SD card and reboot.
