I understand the reason why saving efs makes sense and can help when efs is messed up and I am using linux for a while so i am familiar with dd and tar, but what i don´t fully get is:
* What are the advatages of an image or tarball in this context ? Someone wrote tar would also save file-permissions, but shouldn´t an image save everything exactly byte-by-byte ?
(saw that Paul was using dd and making an image with an older version of the script for SGSII, but bow changed to tar-ball with the MCR-option for GN. Any reason for this ?)
* How to restore img and/or tar - i know how to use dd and tar, but i wonder if restore could/should be done during normal operation or in recovery ?
So maybe someone can shed some more light on this topic for me ;-)
