So @olivier you never answered my question, when does the "Importing" feature get released?

Sorry didn't see the question. What do you mean by importing feature?
-
The topic I posted the other day about restoring a VM, how there is no indication if the import is completed until the vDisk appears.
You mentioned that the VM name would remain "Importing... <name>" and then get renamed
-
@DustinB3403 That's fixed and be out for the 4.12, Friday (or at worst Monday).
If you like to be cutting edge, switch to "next-release" branch on both xo-web and xo-server. It's already in there.
-
@olivier Awesome.
-
Oh and final thing about this AMA-ish stuff: the goal wasn't to complain about EU investors and giving them all the blame, but just to give a picture of the situation, explaining things. Have a nice day lads

Don't leave us for the day
There is so much more we could ask you!
-
@DustinB3403 Go ahead, I'll answer when I can
-
Well this is one question that has kind of nagged me, how do you protect the Xen Orchestra VM?
You can't back it up, using it's self.
-
@DustinB3403 You can backup it if you want ^^ Exporting the backup on a NFS remote share, then if it crashes, re-import a new XOA, connect to the NFS share and reimport it. Tadaaa
No problem to export a running VM, so no problem to export "itself".
-
And very soon, you'll have the "continuous VM replication" allowing you to protect XOA itself too, with a minimal downtime.
-
BTW, I made very interesting tests with ZFS on Linux + XOA delta backups.
Using LZ4 compression is very impressive. Maybe one day integrate the LZ4 compression on the fly into xo-server.

You could run it in a container like me and then just clone the container and export it.
-
What I was planning on doing what at the hypervisor level.
Since I'm running on Xen, I was going to use NAUBackup to simply export a full on a weekly schedule....
-
@olivier I have a quick question. So I ran an incremental backup. I got the green terminated sign, but there was still a snapshot of the VM left. Does XO need the snapshot to restore the deltas from?
-
@johnhooks The only thing needed is a VDI named "XO_DELTA" something like that (visible in the SR view, in the VDI list).
And it's only needed to create delta. You don't need anything to import a backup, you can doing on a freshly installed XenServer (that's the point of a backup: to be useful in case you lost everything)

Ok ya that's what I saw. It showed it as a snapshot but called XO_DELTA something or other. It didn't delete after the job ran so I didn't know if I needed to keep it or not. Thanks!
-
@johnhooks It stays until the next backup: then it's removed and replaced just after by a new delta snapshot. That's because a delta is always created by making a difference between 2 references (the current VM disk and a snapshot).
-
So @olivier is my system not working correctly then?
I have no Snapshots of the VM I've been testing the Delta functionality with, nor do I have any additional vdisk.
-
@DustinB3403 Hmm. You should have a VDI snapshot somewhere in your SR view (that's not visible inside the VM view, only on the SR one)
