Use:
$ rbd -p kvmpool1 snap create --image vm-113-disk-1 BACKUP
"rbd -h" also tells:
<image-name>, <snap-name> are [pool/]name[@snap], or you may specify
individual pieces of names with -p/--pool, --image, and/or --snap.
Never tried it, but you might be able to use:
$ rbd -p kvmpool1 snap create vm-113-disk-1@BACKUP
I don't have access to a running Ceph cluster now to verify this.
