+- Restore of encrypted volume snapshots: snapshots of encrypted volumes are now
+  stored as LUKS-encrypted qcow2 files and decrypted on revert (previously the

+## Encrypted snapshot tests
+
+`test_linstor_encrypted_snapshots.py` covers the encrypted-volume snapshot round trip
+(create encrypted root disk -> snapshot -> revert / create-volume-from-snapshot) and that the
+backed-up qcow2 on secondary storage is itself LUKS encrypted.
+
+Extra prerequisites:
+
+* At least one KVM host with volume-encryption support (`host.encryptionsupported == true`, i.e.
+  cryptsetup/qemu LUKS available). Tests self-skip if none is found.
+* The Linstor resource group used (`acs-basic`) must be able to add a LUKS layer to its volumes.
+* `lin.backup.snapshots` must be enabled (default) so snapshots are backed up to secondary storage;
+  the test sets it. With it disabled the qcow2 path is not exercised.

+#
+# What this exercises (the encrypted-snapshot round trip):
+#  * backup:  decrypted DRBD device  -> LUKS-encrypted qcow2 on secondary
+#  * revert:  encrypted qcow2        -> decrypted, written to the DRBD device (Linstor re-encrypts)
+#  * create:  encrypted qcow2        -> new volume via createVolumeFromSnapshot (KVMStorageProcessor)
+#
+# Note on verification: Linstor encrypts inside the DRBD stack (LUKS layer), so the libvirt domain
+# XML does NOT carry <encryption format='luks'> like hypervisor-based encryption does. Correctness
+# is therefore verified by a data round trip (write marker -> snapshot -> change -> restore -> read),
+# and encryption-at-rest is verified by inspecting the backed-up qcow2 with 'qemu-img info'.
