Oracle Secure Backup Concepts Oracle Secure Backup eliminates integration challenges with ready-to-use tape management software that provides single-vendor support. Oracle Secure Backup also reduces your costs. When using Oracle Secure Backup with RMAN to back up and recover databases and files to and from tape, no third-party tape management software is required. Oracle Secure Backup provides the media management layer needed to use tape storage with RMAN. Centralized administration, heter

Oracle Secure Backup Concepts Oracle Secure Backup is installed can be a client, including hosts that are also media servers or the administrative server. A network-attached storage device that Oracle Secure Backup accesses through NDMP can also serve the client role. Note: A host can be assigned multiple roles in an administrative domain. For example, a host with a tape drive attached could be both the administrative server and media server for a network that includes several other clients

Oracle Secure Backup Concepts A magnetic cassette or tape is sequential-access storage. It has a beginning and an end, which means that to access data in the middle of the tape, a tape device must read through the beginning part of the tape until it locates the desired data. In a typical format, a tape drive writes data to a tape in blocks. The tape drive writes each block in a single operation, leaving gaps between the blocks. The tape runs continuously during the write operation. The bloc

Oracle Secure Backup Concepts When Oracle Secure Backup begins a restore operation, it does not know what block size was used to write a given tape. Because issuing a read for a too-small block would result in an error condition and a tape reposition, Oracle Secure Backup always starts a restore operation by reading the largest possible block size. This is either the current setting of the media/maxblockingfactor policy or the tape drive configuration attribute. The maximum blocking factor,

Oracle Secure Backup Concepts This element is an internal slot in a tape library where a tape cartridge can reside. ■ Data transfer element (dte) This element represents a tape device capable of reading or writing the physical volume. Typically, a data transfer element (DTE) is a tape drive used to back up or restore data on a tape. ■ Medium transport element (mte) This element represents the robotics mechanism used to move tapes between other elements in the tape library. Typically, a medium

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 fu
