Oracle Secure Backup Interfaces
limited storage capacity. If you back up to a virtual tape library, then you can take
advantage of its faster backup and then use the volume migration feature of Oracle
Secure Backup to migrate the data to tapes at a later point of time.
Device Names and Attachments
Because Oracle Secure Backup manages tape drive operations, it must be able to
identify the tape drive and determine whether the tape drive is housed in a tape
library. Oracle Secure Backup must further determine if a storage element is available
for storing a volume while not in use by the tape drive. Thus, each tape device must be
uniquely identified within Oracle Secure Backup by a user-defined name.
Oracle Secure Backup distinguishes a tape device and the means by which the tape
device connects to a host. To be usable by Oracle Secure Backup, each tape device
must have at least one attachment, which describes a data path between a host and the
tape device. An attachment usually includes the identity of a host plus a
name in Linux or UNIX, a device name in Windows, or a NAS device name. In rare
cases, additional information is needed for the attachment definition.
Oracle Secure Backup Interfaces
There are four different interfaces for accessing different elements of Oracle Secure

Secure Backup
Secure Backup Web tool is primarily intended for use in situations where Oracle
Secure Backup is being used independently of an Oracle Database instance. It does
not provide access to database backup and recovery functions.
The Oracle Secure Backup Web tool supports Internet Protocol v4 (IPv4), Internet
Protocol v6 (IPv6), and mixed IPv4/IPv6 environments on all platforms that
support IPv6.
Backup and restore operations for Oracle Database instances and configuration of
