Trusting Open Source for Production...

To boot the full backup of this VM using NAUBackup would be 28GB versus the 16.2GB when compressed.
Assuming I'm reading it correctly, which a delta creates a full, and only copies the changes.
So this next delta that I'm running should only be ~300MB larger. I moved some files over.
-
And wow, here is the completed delta!
-
Did your snapshots disappear after the delta backups were done?

From my primary Hypervisor, yes.
Nothing was saved to the CentOS hypervisor. (does that make sense?)

Ya I got ya. Maybe I didn't wait long enough. I did a delta, and it gave the green terminated, but the snapshots were still there. I'll try it again and wait longer.

So I've waited about 30 minutes or so, much longer after the backup completed. I still have a snapshot called XO_DELTA_BASE_VDI_SNAPSHOT. Am I able to delete it and it not affect the backup or is the delta based off of the snapshot?

hrm... let me connect to my vpn and see (im at home)

Yeah I have zero snapshots on the VM that I'm testing with right now.
I have two hypervisors (both xen) on my production hypervisor I'm running my VM's and XO. On the second hypervisor I'm running the backup target VM.
If it matters any.

Ok I'll have to see what's going on. I have XO in a container on my desktop. I'll try deleting the snapshot and seeing if I can restore from the incremental backup. Maybe it just didn't delete the snapshot.

Great article that talks about this subject: http://mangolassi.it/topic/7468/zdnet-says-open-source-has-won-time-to-move-on
In the discussion about trusting Microsoft but not trusting open source... what happens when Microsoft is the one making open source Linux distros? Does the trust of Microsoft trump the distrust of open source? How do the two compete when they apply equally to the same software?

Did you every get clarification on this? I suspect this is needed for the delta backup.

Yes, it uses the snapshots to make the backups. That's what I figured it was doing, but since Dustin didn't see it I thought maybe something was wrong.
We resolved it in another thread, I can't remember which one at this point.
