Where the OpenNebula VM disk snapshot backup will be stored?

Locate OpenNebula VM disk snapshots on shared GlusterFS storage and inspect the snapshot directory and file sizes from the frontend.

It depends on your storage system.

When your nodes storage are shared, the snapshots are available in front-end. Otherwise, you will need to take a look at the node where the VMs is running.

Let say I have this storage using GlusterFS. This storage are shared between nodes and front-end.

So all disk snapshot are available in front-end.

It located at /var/lib/one/datastores/$ID

├── disk.0.snap
│   ├── 0
│   ├── 1
│   └── 2
└── disk.1


1 directory, 6 files

Those disk.0.snap is the directory where snapshot file stored. I have three snapshot files, as well as shown at Sunstone.

And it's have a same size because I repeat snapshotting without make any change in VM.
