We need to return an SRX 1500 using the RMA process. The unit is coming from a secure environment and trying to find the best way of returning the equipment with least traces of data- short of shredding it. My proposal is
. set system encrypt-configuration-files
. request system autorecovery state clear
. request system zeroize
I see that files are only unlinked during the zeroize process, is there anything else that can be usefully done to remove data?
You have listed the best possible ways.
