I wrote somewhere how to make a backup of not just pcd's e2 image but any e1 image on OE boxes.
Basically, you have to put these 3 files in /usr/bin.
chmod 755 on all of them.
You have to have a hdd built in or mounted via cifs, nfs.
Then just type:
This command in my case looks like this:
because my hdd is mounted on /media/hdd.
Before this, you can kill enigma with init 4 to prevent enigma restart but it is not necessary. This works on any e1 or e2 image for OE boxes. I believe this was the original flash backup script.
Regarding suomipoeka, you would still need to have a pc running with vlc.
