Thanks @olivierlambert
Just to confirm 1. "Main" and 2. "Backup" are 2 physically different machines. Both running xcp-ng
Ultimately I would like to backup the vm's on the physical device 1. "Main" saving it to the physical device 2."Backup"'s zpool drive at /mnt/zfs/
How would I do that?
Also correct...I am not backing up to the same physical media that the vm is on.
Hello & thanks anyone who can help
Setup:
GOAL: Backup the VM's from "Main" to the "Backup" /mnt/zfs Storage Pool .
Problem: I went into Settings/Remotes and created "Local" and the mount point to /mnt/zfs. It accepted that but assigned it a small size of 9.74 GiB Avail. Is there a way for it to have access to the whole 3.5TB the SR sees?
Do I need to install smb share on the "Backup" host then in XO-CE point to the share mount to access the full pool?
BTW: not sure if this is you or not but in https://xcp-ng.org/docs under storage-zfs there is a dead link to "http://www.zfsbuild.com/"
Sadly this is the most help I'm able to contribute but hey at least I read the manual 
Figured it out!
1st thing...thank you for your quick responses.
If anyone else is having problems here was my problem/solution. I had originally installed using a github script from ronivay (not sure if I can put full links in here but google github ronivay XenOrchestraInstallerUpdater...better yet youtube "How To Build XO From Sources on Debian 10 Using XenOrchestraInstallerUpdater" big thankyou to Lawrence Systems.
From there I went into the readme.md where it said the username is xo and pass is xopass (I actually had changed my password but was missing the u/n of xo). Then I got in...hope it helps someone else.
Who new that rtfm would actually work? (Collective forehead smack of all the admins heard across the internet). In all honesty I did read the xcp-ng docs before posting but was looking in the wrong area as I had run the github script so thanks again oliverlambert and Danp for pointing me in the right direction.
Good questions & I can't remember the actually script. Orginally I installed XCP-NG then did a yum update, then ran the command. It was from a youtube video that LTS (lawrence - also a member here) put up. I thought I would check it out in my home lab.
I'll go through the video and find out the command I used.
@olivierlambert xoce = xen orchestra - community edition
Ultimately I want to change the ip of my xo vm. After reading the docs it looks like I have to edit via the cli. My passwords do not work on the cli (they work to log into the xo-ce gui & set as admin.
I can log into the webconfig of XO. I am trying both from the vm console "xo-ce login:" and ssh in as user root. None of my passwords work. I tried creating a new user called root in the webconfig & reboot...that didn't work.
All the documentation I read says to use the cli but that's the problem. Within the webconfig I can't even reboot xo-ce as the operation is blocked. I was hoping to 'e' the boot process and rw init=/bin/bash to gain access.
Any ideas how to reset the root password to gain cli access? NOTE: I can access the shell of xcp-ng (but I think that's irrelevant)
Thanks for any help
@darkbeldin Thanks it was his channel & what great info he provides! It was a 2018 "VM Backups, Disaster Recovery and Continuous Replication with Xen Orchestra Backup NG"
Thanks very much Darkbeldin
xo-server 5.81.2 xo-web 5.86.0
New to this and testing/trying out XCP-NG/XO watching videos on how to use the Community edition. I'm testing the backup section & notice some of the videos show both "Backup" and "Backup NG" in XO. I can't find anything on "NG"
Is "Backup NG" still used? I only have "Backup"
I've installed Orchestra from both instructions which had me typing in everything and also tried using a github script that was updated within a few days ago.
