Re: Is there a way to retrieve SRX full config from J-SPACE ?
Sure, if you configured configuration backups for that device. That's under "Configuration Files->Config Files Management" screen. The most useful way is to set this up as a recurring operation when you do.
Once you a config have backup, you can export/restore them via whatever means you have.
