I have 6 devices that i rsync to a central location to back them up. Ive been using ssh as the -e option. Problem is i use public key with passphrases, meaning to backup all six i need to go to each device and run the backup script. Since i typically backup /etc, /home, and /root this means entering sudo and the ssh passphrase 3x for each device.

I would much prefer a script that runs on back storage device that can pull the data from each device without having to use ssh (encryption is not necessary since all traffic is either local or going through a vpn connection).

I could then put this script in root's crontab or make it a systemd service running as root.

But i dont know how i can remote sync without ssh

You could rsync with directories shared on the local network, like a samba share or similar. It's a bit slower than ssh but for regular incremental backups you probably won't notice any difference, especially when it's supposed to run in the background on a schedule.

Alternatively use a non-password protected ssh key, as already suggested.

You can also write rsync commands or at least a shell script that copies all of your desired directories with one command rather than one per file.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
