NFS boot and backup script with LVM snapshot
After testing and destroying my configuration a couple of time I get tired to backup and restore the SD using dd
So I moved Xbian in an NFS share on my media server following these instruction: http://forum.xbian.org/thread-1531-post-17118.html#pid17118 I created a dedicated ext4 2G volume optimized for speed, following this: http://erikugel.wordpress.com/2011/04/14/the-quest-for-the-fastest-linux-filesystem/ The volume is mounted as: Code: /dev/VG1/Xbian /srv/Xbian ext4 noatime,nodiratime,data=writeback,stripe=16,barrier=0,errors=remount-ro,nobh 1 1 and exported as: Code: /srv/Xbian 192.168.1.208(rw,sync,nohide,no_root_squash,no_subtree_check) The I made a script to make a daily full backup, using LVM snapshot to keep a consistent copy. I keep only the last 7 backup Code: #!/bin/bash If you don't have an LVM setup you can use the script removing the lvm and mount parts. Now I'm planning to add a scheduled script in Xbian to backup the boot partition on the nfs volume: Code: mount /boot -o remount,ro |
