I am trying to backup to ehdd while on a liveUSB but when I write
$dd if=/dev/sda6 bs=8M | gzip -9 > /media/usb/backupimage.gz
I get the message "failed to open /dev/sda6':Permission denied (the /home/folder in there is encrypted).
What do I need to do?
I want to backup before resizing partitions with gparted before reinstalling system.
