Vates Tech Support

Yes, all the code related to Netbox is in there. If you have time to take a look, you'll find your answers there

We can probably provide a list of objects we are using to sync, that might be helpful.

@pdonias will do that when he can (he's pretty busy right now)

"Recovery" is only an option for PV guest (not HVM), when you want to re-use the initial bootloader. It has nothing to do to recover anything else.

You should be in HVM for all your VMs by the way, it's more secure and even faster.

Yes, smart mode seems to be the answer

Yes, it means you must keep the latest viable snapshot on the DR site. This will require to be sure when we want to revert the DR, in XO, that both snapshots on source and dest are the ones expected (otherwise, this won't work and get corrupted result).

So we might need to add something in the snap to check that's the right one.

Anyway, this is not trivial. Let's see what @julien-f think when he's around. After that, we'll have to decide to put it in the backlog (which is already stuffed as a Thanksgiving turkey)

Ping @pdonias even if I think this will be done in XO 6 anyway

The whole problem is to be sure to apply a delta that would make sense.

For example, you can't apply new blocks on something different that you had when you sent those blocks. It's not trivial to explain, sorry

In short, you should be able to revert ONLY if you could rollback the original VM to the latest sync snapshot of your CR. In that case, it's indeed possible to reverse (not automatically, just talking from a blocks perspective).

But this requires to compare (or to know) the exact right diff between the original/latest snap you took on the original site, and send ONLY the diff since that. On destination, you need then to export a delta between the content of this snap and the current situation.

However, it's possible you didn't keep the same "last" snapshot (due to retention) on the destination. So it means there's no way to send the right delta.

The other alternative would be to compute a delta between 2 completely different storage. That will be possible with SMAPIv3 I believe.
