I am currently using a combination of dd, gzip and nc to remote backup the flash of an arm board.
dd if=/dev/nand conv=sync,noerror bs=64K | gzip -c -9 | nc 192.168.0.123 8000
I'd like to ask whether there is an efficient way to omit nc and transfer the data via ssh.
Furthermore, I am also looking for a solution where the backup process is initiated by the 'backup server'.
