Before Fangtooth introduced INCUS for virtualization all the disk images (ZVOLS) for your VMs where stored in a dataset that you could access using the Data Protection options in TrueNAS. In my case I was using the Periodic Snapshot Tasks and the Replication Tasks to take a snapshot regularly and then replicate those snapshots to a different pool on the same server and also to another server over a dedicated replication Ethernet connection. While perhaps overkill this has saved my butt quite a few times when I’m doing testing on my lab machines and when i recently moved and the pool on my main server got hosed.
Now under Fangtooth and INCUS the dataset location where the disk images are stored is no longer on an accessible dataset, i.e. the (pool)/.ix-virt location does not show up in the list of snapshotable datasets.
Wondering if anyone here has any ideas on how to preserve what to me seems like a pretty basic ability to have for VMs, the ability to snapshot them.
