    @dthenot I cannot express how grateful I am for pointing me to this thread, I've been trying to find something like this for months googling stuff around and it seemed like that thread eluded me! Much thanks!

    @Danp Looking into it looks like VMs were doing full backups everytime when suppose to be delta backups... Let me know where else i can look to verify, but this is what i see when i look at the backups.

    Yes, they are created either: on demand for users when we need in XO 6 Now, XO 6 is becoming the main driver for new endpoint as the UI is providing more and more features.

    @carloum70 Disk migration isn't supported by the provider yet. What you can do it's only ignore the changes to the sr_id of a given disk. For example for the first disk: lifecycle { ignore_changes = [ disk[0].sr_id ] } You can also manually do the migration in XO and then after edit your HCL to update the sr_id with the new ID. It should do the trick.

    @olivierlambert said in Detached Backups: You can do that already if you like (combined rolling snap and delta backup). But what's the point? Oh, wow. You can combine backup methods in the same job (as long as they are compatible methods (i.e. Delta and CR). This is cool. I currently have separate jobs for my deltas and CRs. I'll need to make time to make the changes, but this will simply things greatly. I'll even throw in a few extra snapshots to retain. So, yea, this is pretty much what I was thinking of. I didn't realize it was there. Why would I need this? Well, when my WSUS installed the Xen drivers on all my Windows VMs, I went a day before realizing what happened. A snapshot would have been sufficient, if I had one from the day before. Instead, I restored the backup which broke the chain. @olivierlambert said in Detached Backups: edit: about your previous question, restoring without breaking the chain. That might be possible. In theory, after restore, we should take a snapshot before booting the backup and then re-link the restored VM to the backup folders. It's doable (renaming some folders correctly) but I'm not sure this will be very useful. I'll look into this when I get some time. Thanks.

    @spidernin If you go to Backup > Restore, it will show you the number of existing backups for each VM.

    Hi, If you want to change the background color, you need to update the $side-menu-bg: #044b7f; in ~/xen-orchestra/packages/xo-web/src/index.scss . Best regards.

    That's precisely the difference: a delta backup is stored in a remote, a CR is stored in an SR.

    Not a huge deal currently, but if I had a number of VDI's spread out, it could exeed any single available space which means I cant restore at all... Can this be done in an alternative way via CLI?

    What does your cloud config logs show on the guest OS after boot? Can you see if it has made any attempt to inject the config? Only thing I can think of is that your cloud config might be wrong thus the cloud init service is refusing it. Have you tried to use an ubuntu image? I used official images of both debian 10 and ubuntu 18.04 and worked fine once I got rid of the pre-populated network config or inserted a real network config. I spent too long trying to figure out what was going on so let me know if there's anything else you need to know, it's super frustrating.

    Question: Delta backup retention vs. full backup interval

    @Vinylrider your understanding is correct, delta retention is just how many deltas to keep before merging the oldest delta with the full. Full backup interval is the time between each new full back up for use in case of corrupted back up. To answer your question, yes it is recommended to have more than 1 full back up to fall back to in the event of corruption espcially of delta backups since delta backups rely on previous deltas meaning if one of your delta is corrupted, you'll loose all data from that point onward until another full backup is made, or worse your full backup could be corrupted (more likely because of the file size) then you loose the whole chain. And if your corrupted delta is merged with the full, you'll probably have a corrupted chain aswell.
