automigration (VLS specific term) The functionality that allows data backups
to be first made to the VLS' virtual tapes and then migrated to
physical tapes (one virtual tape emulating one physical tape)
without using an intermediate backup application.
See also Virtual Library System (VLS) and virtual tape.
BACKINT (SAP R/3 specific term) SAP R/3 backup programs can call the

• Mount point: For filesystem objects — the access point in a
directory structure on the client where the backup object is
