For me, my high bar that I have yet to beat, was the time I pivoted the running OS (ubuntu) into RAM over SSH so I could unmount and image the boot drive without rebooting and loading a live USB (Which would have required a ticket with my provider to enable IPMI)
scp
I’m never using a flash drive again.
especially nice when you get path completion on the target server :D
Note: to do this you have to have your public key on the remote server
Next step: rsync, because it lets you resume.
