No problem! Glad it helped

No problem

After working perfectly luckybackup stopped working. id_rsa and is_rsa.pub are no longer visible in the 'remote' tab during setup, only known_hosts (file size is reporting wrong too). I used CLI to verify they are in fact there, but no 'luck' (nice pun, thank you very much) through luckybackup. thoughts? On my system the /root/.ssh folder is reporting as a symlink pointing to /boot/config/plugins/dockerMan/ -- is that supposed to to do that? I don't think luckybackup is following the correct path the generated key

Man you really got me on this one. A sym link sounds fun but the path seems wrong. I think. Anyway, I’d maybe adjust the permissions of the id_rsa key and see if they appear. Maybe a chmod 644 or 655.

@@SPXLabs Thanks for the reply! I tried changing permissions but no luck. People are reporting that in Unraid 6.10.x a lot of issues surrounding permission got out of whack. I did not generate the symlink, not sure why the system automatically did that. I didn't try changing permissions of the 'boot' folder that the symlink is pointing to, I will try that first then if that fails I will try to create a new .SSH folder directly in root that does not point to the boot folder. The only think i know for sure is that luckybackup doesn't see the rsa files I generated. thanks again for the troubleshooting, I respect that you're not my tech support, you kindly made this great guide and I appreciate that! I will let you know if it works.

What happens if you move the keys inside the default directory that lucky backup tries to use?

@@SPXLabs thanks! Turns out that the luckybackup volume mapping was off, so it was trying to find keys in a folder that didn't exist. I was able to correct that and we're up and running. thanks again.

Never leave home without one!

Nice. As you may know I too prefer the bash script method.

@@SPXLabs BTW the Airgap is important, a few feet at least - I lost a lot of equipment when a lightning strike came down 30 ft from the house, into the ground ... while I was sitting there with a window open ;-) AWESOME. Nature's power.

@jay kastner Can you share the code please?

@@AviDarks it's pretty simple, and i run this manually w/o CRON etc #! /bin/bash umount /dev/sdc1 mount /dev/sdc1 /media/extern rsync -aAXvh --delete /media/data /media/extern rsync -aAXvh --delete /media/moredata /media/extern rsync -aAXvh --delete /media/evenmoredata /media/extern BTW my drives use all ext4

I'll see if I can make something for external drives but not going to lie I'd still probably use rsync + the User Scripts plugin. I feel like it's just easier. Also also consider hosting WikiJS to document stuff in the future that way you can relieve your success in the future.

this is exactly what I am trying to figure out at the moment, any advice or could you point me in the right direction? I know zero about scripts :/ total noob.

Even if you tried to do everything command line? I know GUI's are nice but rsync is relatively simple aside from the absolutely massively long command with variables.

In the latest version of unraid there is a symbolic link in /root/.ssh that points to /boot/config/.ssh or whatever the path is. So they keys get put on the usb drive already.

@@SPXLabs thanks for the clarification! That's great to know

BUT in retrospective I think that if the container updates the keys generated in the container will have to be regenerated

@@SPXLabs yeah I guess that could be mapped through to the container from the host so they're preserved? However the private key will then be in a share on the array or something

@@TomWhi It could be, by default some keys are mapped in the appdata directory that comes with the container but I couldn't get any of the pre-provided keys to work.

Like backup Windows data that is on your PC to Unraid?

I think you can't browse the remote directories because LuckyBackup doesn't establish a connection with the server until you run the commands. You will just have to know what the path is before hand not sure of a better way.

Just an FYI, I don't use this method daily. In my opinion it's more complicated than the method that I use. My preferred method is using RSYNC with User Scripts for weekly backups. It has worked flawlessly for months and is not effected by container updates. kzfaq.info/get/bejne/pcplZstllc_RgXU.html

Yes. You can use user scripts to send a magic packet to make another computer turn on. It’s call “Wake On LAN”. Then after a backup finishes you can use a script to ssh and shutdown the remote computer.

@@SPXLabs OK thanks! I'm still new to this unraid server stuff. Do you know of a tutorial that shows how to do this?

I do not know if one off the top of my head. Also I’d start with making sure your MOBO supports WOL

Ok thanks. 🙂

Make sure the directories / mount point is correct. Restart the container. If neither of those work… then maybe change permissions of the files to something like 644. chmod 644 id_rsa*

I have absolutely no idea how any of this works for what you are trying to do.

Depends on your budget I suppose. I rock a Unifi XG 16 but I don’t believe they sell them anymore.

@@SPXLabs Thank you. I opted for Mikrotik switch and the SFP+ Mikrotik offers as well. Downside is the negotiation needs to be manually set for 10G otherwise the upload speed is dismal compared to the download speed for a 5000 mb/s connection. (about 4300 mbps down but up is 250 mbps).

I haven't tried it personally but I'd imagine it would require manipulating the sshd_config or maybe another ssh plugin.

Thanks for posting your solution. I ran into the same problem myself.

@SteveHill68K You welcome. It can be a pain trying to figure this stuff out.

Well, that's really a question I can't answer because it depends on you. However, I can give you tons of information to figure out if you should do it or not. Synchronize source & destination Use this task type in order to sync the source with the destination by keeping the most recent files at both of them. It can prove really useful if you modify specific files from different locations. **Please note that if you delete files at either the source or the destination and you perform this task, you will end up with these files created again because they still exist at the other location. Example: Let's assume that you are working on a project. You have created the directory /home/luckyb/project at your home PC and save all relevant files in there. At the same time there is a need to work on some of these files at another PC, so you copy them at your usb flash drive (location: /media/myUSB/project). There are times when you do not remember which file you edited when and from where. So you create a task declaring: source: /home/luckyb/project/ destination: /media/myUSB/project/ task type: “sync directories” This will result in a 2-way transfer. Newest modified files will be transfered from source to destination or the other way round. Also freshly created files at one of the locations will be copied over to the other.

I don’t believe so. If Windows has rsync or the ability to install it then probably yea

@@SPXLabs Windows doesn't have rsync, but you can setup rsync on a Linux machine to access Windows shares. That's why i thought maybe this might work the same way too.

Oh okay. I'm not too familiar with Windows like that so I can't say for sure.

Personally I feel that this was is more complex than my preferred way of just using rsync in “User Scripts” but everyone is too afraid to type in some very simple commands. I think you would be better off just using rsync. You could also technically map/mount both servers to the same computer then drag and drop files. But I wouldn’t recommend it.

No problem. I haven’t heard of anyone claiming it’s meant for business, I hope no one is.

I do both local and distance.

It sounds like the ssh keys aren’t working correctly or aren’t shared correctly. Is there a way in Qnap to disable password authentication? That’s not a good idea but you could test it out and see what happens. You can use sshpass with rsync to add the password to the rsync command but that also isn’t a very good approach.

@@SPXLabs Thanks. Yes its possible to remove password. I found a way just to use SMB password. I mounted SMB in unraid and then added the shares to luckybackup container. And boom. Amazing sync and backup for us who like GUI. 4 hours and 15 minutes copying 211 000 files and about 2,6TB. Had to compress small files to rar and then i saved about 4 hours each time i take backup. And now i got 2 servers in sync and one backup pluss nextcloud to PCs.
