This is good advice, thank you. I've had OpenSSH installed by the
Windows admin for me, so I can now ssh into that Windows host and even
public key authentication works:
root at bsd:~ # ssh winhost ver
Microsoft Windows [Version 6.1.7601]
root at bsd:~ #
Now that I would like to send the backups to winhost to b:\my_backups\,
what remote command should I call there? In Unix I would call "cat" or
"dd" or even "rmt", but here?
root at bsd:~ # zfs send zroot/var/mail at test | ssh winhost "what?"
I guess I need something in Windows that would accept a byte stream on
stdin and save it to a file in b:\my_backups\
