On the cascaded 3DC network, data links must be established between the
production center A and same-city disaster recovery center B as well as between the
same-city disaster recovery center B and remote disaster recovery center C. Same-
city disaster recovery is implemented between the production center A and same-
city disaster recovery center B using HyperMetro. The primary file system of
HyperVault serves as the secondary file system of HyperMetro, making remote
disaster recovery of file systems in the production center A available. Local backup
of HyperVault can be implemented on the primary file system of HyperVault.
