Backup and Recovery Goals

And does it have to run on a separate server to create that backup file?

Can Unitrends build a complete backup that can be imported to a Xenserver should the Guest VM get corrected?
Not sure what you mean. Unitrends handles every aspect of XenServer.

It would run as a VM. VMs have no means of knowing if they are local or not.

But does breaking this appart from StorageCraft actually make sense? Assuming you're a Unitrends shop you typically wouldn't do that. You'd have Unitrends do everything.
i agree. Find one tool that does the job and stick with it. Trying to use two separate tools is making this incredibly complex and complexity is just another term for risky.
-
I'm just a bit confused on how it would work, as I haven't use StorageCraft on XenServer, and I'm thinking of it just like "trying to format a windows partition
that you're using to run the command from" -
Or I guess the better way to explain it.
How do I restore from Storage Craft if I want to simply dump a corrupt VM? Does it build a .xva, .ova, or vhd backup?
-
It depends on how the backups work. If the backup is a client piece inside the OS, then there are a few options for restoring the system, but if the backup works with the VM platform, then it can probably just restore whatever file format Xen uses.
As for the OS type, the two options I know of are - you recreate the VM in the VM software, then install Windows, then install the client software for the backup solution, then restore the data.
option two, you create the VM just like above, but this time you boot it from an ISO, or PXE, etc and connect to the backup solution, choose your restore point and it's pushed to the server. When it's done, reboot and you're done. -

Normal way that you restore physical systems: https://www.storagecraft.com/support/book/shadowprotect-user-guide/restoring-volume

Unitrends is the only backup software that does that for XenServer other than just taking your own image. We've never found another tool that talks to XS.

And this is why I think Xen is a bad choice for Dustin to stay with. He can get a better solution by moving to Hyper-V, it's almost assured that StorageCraft can restore direct to VHD - but if it can't.. ok fine, stay with Xen.

No, why would you assume that? StorageCraft is the same on every platform. It definitely does nothing special with HyperV.

OK - Most VM specific products work at the VM level (I have no clue if SC does or not). I would think that would be the best place to work from for a complete recovery solution.
Are you saying SC doesn't backup the VHD?
in thinking about this - perhaps I'm giving more credit than is really due to most VM backup solutions... I'll stand corrected if that's the case.

Correct. It is an agent backup from inside the VM.

So Veeam and Unitrends are the two primary ones that work at the VM level?

You two lost me....

Correct. Which is why they are the only two discussed in most contexts. And Unitrends alone handles XenServer.

Two fundamental types of backups: Agentless that talks to the platform and Agent-based that works from inside the VM.
Unitrends and Veeam do Agentless.
Everyone except Veeam does Agent.
You have to think about each differently. Are you backing up from the platform or from the OS. Platform backups are useless when dealing with physical boxes always.
-
What I'm running now for our separate XenServer is Platform backup and restore.
The guest don't get a choice in it, and it's really, really simple to restore from. Import and done.
-
I see the appeal in "import and done" once you do the import of the NAUBackup image, you still have to run the restore from the SC to get your differentials from the last full image. I'm not sure SC would be able to do that easily as SC wouldn't be aware of when the last full backup was done.
