Using a method I previously wrote about, it’s quite easy to backup your Beaglebone Black over the network.
ssh root@bbb 'tar cf - / 2>/dev/null' | pv -cN tar \ | bzip2 | pv -cN bzip2 > bbb-backup-tar.bz2
It runs the bzip compression locally because presumably it will be faster than on the Beaglebone Black. I didn’t actually test that hypothesis though.
pv gives nice little indicators:
bzip2: 1.81MB 0:00:12 [ 995kB/s] [ <=> ] tar: 36.2MB 0:00:12 [3.84MB/s] [ <=> ]
