Wild Card questions file copy with fs-ops

#1

I had an accident with a corrupt (brand new!) SD card in one of my Pi's today, and I didn't have backups of the three hours I worked on Node-RED and Home Assistant yesterday. Luckily I managed to mount the card in a reader and use Recuva on a pc to find everything, so I lost nothing. But it scared the living crap out of me, so I want a fully automated system that copies (wich schedex) the files that I need to backup every night to a share on my server. But I have one slight problem with that: I want to copy all *.yaml files to that directory. Do I need to make one node for each of them, or can I in some way do a wild card copy? Either I didn't find the full instructions, or they imply that the reader knows a lot more about this stuff than I do. :blush:

Use one of the backup systems such as backintime or borgbackup.

Thanks, but I would prefer the simple copy function in Node-RED, which I can spread out to my six Pi's in a few minutes without installing anything else. I already have the system set up, I only need the wildcard stuff working.

you can always call out to a system copy command with the exec node.

Probably, but then I wouldn't easily get a message telling me if it went wrong, would I? The fs-ops can do that.

well it returns stdout and stderr so yes it should.

Good point Dave, I always forget that!

That works, thanks! But it doesn't give any messages when the copy didn't fail, and I think that would be easier to catch than a message when it fails. Because the fail messages can have different reasons (directory not found, copy protected and so on), I'm afraid that I won't get the message if something ahppens. Is there a way to get a confirmation? Maybe with afile excists or something?

Have you debugged all the outputs of the node?
You can also use a status node to monitor the exec node!

Yeah, I have a debug on it, and it doesn't show anything at all when the copy is successful. But I think I can use fs-ops' File Access node to check for the files and send a message if they don't excist.

Can you post the flow?

Sorry, my mistake. I was on the wrong output of the exec node. It gives a payload of 0 when it's done.

Here's the flow. Note that it uses fs-ops to creat the directory with date and time of copy:

So if you get a code 0 you know it was successful.
