Hi Spuluka.
I Just want to confirm my understanding is correct
set system auto-snapshot.
The above command will perform followings:
1) When even there is a change in the config, alt config folder gets updated.
2) If some reason, router boots up from Secondary , then command also overwrite root and config folders with the contents of alt root and alt config.
The link you have provided does not say anything about (1). I am assuming but this is how it works eventhough link does not say anything it.
Also when we use set system auto-snapshot, does it also copies JUNOS packages from /root to ALT/root ? or do we have to use request system snapshot?
Appreciated all the help!!
