Backing up internal flash memory

[wpervaiz]

I've installed, upgraded and configured ubuntu according to my liking. I've also installed an apache webserver and other applications. Everything is on the internal flash memory so I dont have to use an sd card. My SheevaPlug is running perfectly.

What I want to do now is to copy over everything in this plug onto a second (and maybe a third) plug. Is it possible to make an image of everything on the sheevaplug and just copy and paste it onto another plug to get a duplicate install ?

Thanks!

bump, anyone ?

I can partially help you.  Here's what I do to back up my SDcard.  I think it should also work fine to back up the internal flash:

First, on the Backup Machine:

Code:

$ nc -lp 2345 | gzip >sheeva-root-fs-$(date +%F).cgz

Then, on the SheevaPlug:

Code:

# BKUPIP=<IP address of backup machine>
# cd / && find . dev -mount | cpio -oc | nc $BKUPIP 2345

You can interrupt the processes on the SheevaPlug after the "XXXX blocks" message appears there, and you should then have a good cpio archive on the backup machine.

This should create a remote backup of your root file system (plus /dev, some of which is necessary to boot).  However, I've never looked into what is necessary to get it onto a second Plug's internal flash memory because I don't generally use this configuration.  I suppose if it were me, I'd boot the second Plug off of an SDcard, set up the internal flash as a mounted FS and restore it, and then reset the Uboot parms to boot using the internal flash, but perhaps someone else can suggest a more elegant solution...

Good luck!
