I know I have been down this road before, but slightly differently this time. I have a script to backup node-red stuff locally on the same machine. As things go on, I am needing to now access a remote machine (probably a NUC, but who knows at this stage) and copy files from the machine to the rem…

rsync can be used for local backup creation, but the r in rsync stands for remote, usage: rsync options source destination There is always security in between, rsync has an environment variable available for supplying passwords (RSYNC_PASSWORD). To make life easier, use ssh key pairs between your…

Yes, I have keys between the machines. Though I think it is only one way. (Luckily it is the right way) But there is a "master password" used so I don't have to remember umpteen passwords. Just one. Will this cause problems?

no - you can just scp in (or rsync) and copy the files from the remote directory. nothing needs to be mounted. As long as the remote user can a) login to the client computer and b) has permission to read the files in that directory then it should be fine. So in my case I log as "pi" user and use the…

Yeah, I have all that set up. Now just getting it working in the node. Alas the errors are not helpful at this stage. I am adopting your idea that the sever gets the file from the remote machines. I can SSH to the remote machine/s ok - but I need to enter the master password - to log in. In the…

typically an rsync command would look like rsync -avz ssh pi@192.168.0.100:/home/pi/.node-red mylocalBackupDir1/

[image] dceejay: typically an rsync command would look like rsync -avz ssh pi@192.168.0.100:/home/pi/.node-red mylocalBackupDir1/ Um, sorry. Putting aside the IP number that doesn't work. However if I try: rsync -avz pi@192.168.0.93:/home/pi/.node-red /home/me/TEMP/NR/ It works. What is…

Ok, but if I am using the node , where does the -avz come in? Linux has a nice command available for you if you don't understand what something does: man (manual) man rsync and if you don't have it installed you can google for it. rsync(1) - Linux man page Rsync is a fast and extra…

Yes, but . . . . . The example is for "cli" use. I get that. But I seem to remember it being pointed out that there is a rsync node for NR which simplifies the use. I was trying to use the rsync node. So using what @dceejay posted I tried it from a CLI. Error. Modifying it to what I posted…

But I seem to remember it being pointed out that there is a rsync node for NR which simplifies the use. Touche. I digress :wink: didn't look at the actual node. rsync -avz ssh pi@192.168.0.93:/home/pi/.node-red home/me/TEMP/NR/ should be; source - destination rsync -avz ssh /home/me/TEMP/N…
