@olivierlambert I was able to sort out the issue, it has to do with licensing and the fact that we aren't licensed to with "Live Migration" for this ESXi host.
Essentially this inquiry is solved.

The reason you wouldn't want to look at XO for this from a technical standpoint is because XO works at the hardware level of the hypervisor, dolling out resources to different VMs and creating backups.
You need to look at the content within a given VM and compare the file system difference from points A and B.
Only something that is operating within the file system would be able to readily tell you "Something has changed".
Odds are you have a user or several who are dumping files onto a share that they shouldn't be, or are replicating some cloud service to keep a copy on your server etc.
A question
You can disable all of the boot devices in the Advanced section of the VM, try disabling the HDD
Disable the Boot options if your system is making it past POST to quickly so you can get into the Guests BIOS.
@jasonnix said in A question for the creators of XO:
Hi @olivierlambert,
No, I'm not a bot. I asked it because I need your experiences. I want to make a panel for Xen.
So you know how to program with PHP and Ruby and not with Javascript, so the question is really "Why can't this be rewritten so I can help?"
For laughs I am testing with a VM that is powered off and its going, albeit slowly (likely due to a 10FDx port on the ESXi host).
@Danp said in Run a script inside guest OS from host:
@ajpri1998 What about using something like
psexec
or
the powershell commandInvoke-Command
?
Exactly what I was going to recommend, but the request is to be sent from XCP-ng (the hypervisor) rather than some management server..
What would the Windows PowerShell command be doing within the VM, that resides on XCP-ng?
and
Why does the hypervisor need to issue the command to the VM?
@lawrencesystems said in Delta backup questions:
If you choose 2 storage destinations it will copy to each of them at the same time.
As a discrete backup that is saved to each location individually.
@emiltmx said in Restoring from backup failing:
@DustinB even if the old installation is an older version of XO?
We were running 5.74 on the old one, 5.91 on the new one (I think? Xen Orchestra, commit 838f9).
I can't say for certain that the config hasn't undergone any major changes, but you should at least test it.
ok but I don't see where I can create vm gourp or how to assign acl on vm tag? can you help me ?
regards
Are you using XOA (the paid appliance or trial)? If so you should have access, otherwise you should perform a google search for a few of the different installation scripts for xen orchestra community edition that exist.
I had to replace my XOA recently to complete an update, as the patching just kept failing.
Once I restored the config, my jobs restored as well but hadn't automatically ran, I manually kicked off my daily job and things have been running since.
I'm not sure why I had to do this, I only happened to noticed my daily didn't run and manually doing so worked, and its continued since.
@rtjdamen said in Why does the backup use snapshots and not CBT:
@olivierlambert indeed, what about xenserver compatible backups solutions, can they work on xcp as well? I see we could maybe use agent based backups inside the vms for the larger ones, i will test this with one vm, but need a proper solution in the future, i believe if we can get this to work in xoa that would be the best solution.
You should look into something that is Application Aware (SQL etc) for these systems as they are likely sensitive to interruptions.
I don't know of any opensource agent based Application Aware backup solutions that would work, (edit) easily enough and not cause other headaches. Of course you would likely only be backing up your database with one of these separate tools and then use XO to restore the guest as a whole and restore whatever database there-after.
Off the top of my head a few backup solutions I've seen and used
I know Bacula is/can be application aware in their paid version but I'm not sure if the opensource edition offers it.

@julien-f said in XO Backup Advanced Backup Schedules:
@olivierlambert It's a limitation of CRON patterns, to support this we need to implement it separately and design a dedicated UI.
@olivierlambert said in XO Backup Advanced Backup Schedules:
Eg like an "advanced" dedicated field to replace the UI and put directly the cron pattern we want, that would work?
Sounds like it, but you would also need to ensure that if the "Advanced Schedule" is configured that the default option cannot be enabled and used.
Which in my case would be fine.
@rtjdamen said in Why does the backup use snapshots and not CBT:
@olivierlambert ok would be great if we can get this working, will be a huge improvement.
I concur, I've gotten my backup window down to around an hour, but still the amount of delta in each backup nightly is like 50GB, which doesn't seem feasible given the amount of delta is actually occurring.
@CJ Restart the toolstack to clear out the phantom migration.
@aqua-calc You have this job running every minute, is that what you intended? Is it possible that the backup job is simply already running and can't continue with another execution.
@aqua-calc Can you post the screenshot here in the forums, I'm not willing to go to a web page that is app dot screencast dot com when you can post the picture here.
