Test purpose To verify that the CSC preserves and recovers the state and data of storage.
Reference [ITU-T Y.3513] clause 7.2.2
Test sequence Step Type Description Result
1 Stimulus The CSC takes a storage snapshot of storage A, called
snapshot A.
2 Stimulus The CSC changes the data of storage A.
3 Stimulus The CSC takes another storage snapshot of storage A, called
snapshot B.

4 Stimulus The CSC restores snapshot A.
5 Check Storage A's state and data are consistent with the states
when snapshot A was taken.
6 Stimulus The CSC deletes snapshot A.
7 Check Snapshot A can be deleted without affecting snapshot B.
8 Stimulus The CSC restores snapshot B.

9 Check Storage A's state and data are consistent with the states
when snapshot B was taken.
Test verdict It is deemed as successfully terminated if all the checks are successful, otherwise it is
deemed as failed.

occurs.
Reference [ITU-T Y.3513] clause 7.2.3
Test sequence Step Type Description Result
1 Stimulus The CSC takes a storage backup of storage A, called backup
storage A.
2 Stimulus The CSC changes the data in the storage A.
3 Stimulus The CSC restores storage A with storage backup A.
4 Check Configuration and data of backup storage A is consistent with
storage A.
