I've been using Clonezilla for weekly image backups, which is obviously a little bit of a hassle. I've been trying to switch to dd, so I can have cron run it for me.
This is what my backup script looks like:
#!/bin/bash #dd whole drive dd if=/dev/sda of=/media/temp/image/"image-$(date +"%Y-%m-%d").img"
I ended up with a 256gb img file, and decided to give it a test run. I booted from the Ubuntu 14.10 live USB stick, mounted the remote filesystem, and ran the following:
sudo -i dd if=/media/temp/image/image-2015-04-04.img of=/dev/sda
Upon rebooting, the system hangs at the "Ubuntu" logo screen. I'm unable to switch to tty1, ctrl+alt+del, or anything. I then restored from my Clonezilla backup (which was made immediately before the dd backup), and it worked fine.
What am I doing wrong? Should I just ditch dd and take a different route?
