VM Backup Plugin

[JTok 71]

Mod note: this plugin has multiple known issues, use with care.

 

This is a beta version of a plugin I am working on to replace the unraid-vmbackup script I have been maintaining here and here.

It is based off the latest version of the script (v1.3.1), and I will be maintaining both for now as there are some use-cases for the script that the plugin cannot currently replace. This is provided as-is with no guarantees.

 

That said, and without further ado, the current version of the plugin can be found here:

Run the beta  plugin. Perfect!!

I did however pull it from your link as I couldnt find it in Community Applications,

 

Thank you very much.

Works very well so far, well done. One request would be to allow unassigned devices to be used as the backup location, it only allows unraid shares at the moment.

You should be able to manually type any path that starts with /mnt/ even though the drop down list only shows shares.

 

 

If you need  a path that starts with something other than /mnt/:
Under the Danger Zone tab, at the very bottom. there is a setting called “Disable restrictive validation”. If you set it to ‘Yes’, it should allow you to chose any path.

@JTok Big thanks in the first place for your work. Looks like the plugin works for me with a quick test on a single VM, normal backup+compression. A small issue I've found is when selecting the target path for the backup. It's basically not possible to read the dropdown menu items. I'am using the Black theme with Firefox. Same with Brave browser and Chrome on Unraid 6.8. Just to let you know.

I tried manually typing the path but without changing the mode and it would not allow. Will try again. Thanks

Make sure the path you’re typing contains a trailing slash. I’m going to change that requirement in a future release, but I didn’t change it yet for the beta.

I'm sure the trailing Slash was there. Will try again and report back

Weird. I’ll check it out. Thanks

@JTok Just one little thing I need is a big red button labled "BACKUP NOW"  😂

Very cool, can't wait to give it a whirl.

Quick question: do you plan to add restore capability at some point?

No, I stand corrected you were quite right, trailing Slash did work fine.

yeah! That’s on my radar! When testing, it was a little frustrating at times without one.

I hadn’t really thought about it, but I probably should lol.

I’ll put that on my to-do list, but that’s probably a post-beta feature right now.

I second that request (for restore functionality).
No hurry, but that would be a valuable addition.

Yeah, it would be good. Initially though just information about how to do it manually is good enough.

Here's my draft at manual instructions, feel free to use them as a starting point. I just backed up one VM as a test in this case.

1. Stop all VMs.

2. Take a peek at what VMs you're using and where you're backing them up. Here's my config:

This means I should be able to find a directory here:

/mnt/user/Saidin/backuptest/Forsaken

3. Open a command shell.

4. Now you need to copy your VM vdisk and VM xml to the right location. If you're truly restoring, you'll need to make some directories as well. I'm assuming you're using the default location for domain disks, /domains share.

root@Truesource:/# mkdir /mnt/user/domains/Forsaken
root@Truesource:/# cp /mnt/user/Saidin/backuptest/Forsaken/20191220_1017_vdisk1.img /mnt/user/domains/Forsaken/vdisk1.img 
root@Truesource:/# cp /mnt/user/Saidin/backuptest/Forsaken/20191220_1017_Forsaken.xml /etc/libvirt/qemu/Forsaken.xml 

5. Start your VM.

Will this eventually get added to CA so it will update automatically?

unRAID should still detect updates in the plugin screen without it being part of CA (assuming I didn’t mess something up). And the CA update plugin should also still do automatic updates from what I can tell.

 

That said, I've been in contact with Squid about adding it, so that should get done soon.

hmm it didn't for me, but maybe I was too quick - dunno.  Thanks again for making this into a plugin.

Hi,

 

Great Job - I've been using your script for a while and it save me a lot of time. Thanks for that!

 

Could you add an option to not backup/stop running vm's?

Would it be possible to set up different amount of days/backups for each vm?
