Zero Data Loss Recovery Appliance (Recovery Appliance) is a cloud-scale Engineered
System that is designed to protect all the Oracle Databases in your enterprise. It
achieves significant efficiencies in performance and manageability of backups by
offloading most Oracle Database backup and restore processing to a centralized
Recovery Appliance.
零數(shù)據(jù)丟失恢復設備（恢復設備）是一種云規(guī)模工程化系統(tǒng)，旨在保護企業(yè)中的所有Oracle數(shù)據(jù)庫可婶。 通過將大多數(shù)Oracle數(shù)據(jù)庫備份和恢復處理分流到集中式恢復設備沿癞，可以顯著提高備份的性能和可管理性。
Recovery Appliance stores and manages backups of multiple databases on a unified
disk pool, using an incremental-forever backup strategy described in “About the
Incremental-Forever Backup Strategy for Recovery Appliance”. It continually
compresses, deduplicates, and validates backups at the Oracle block level, while
quickly creating full virtual backups on demand.
恢復設備在統(tǒng)一存儲和管理多個數(shù)據(jù)庫的備份磁盤池矛渴，使用增量 - 永遠備份策略中描述的“關于恢復設備的增量 - 永久備份策略“椎扬。 它不斷壓縮，重復數(shù)據(jù)刪除和驗證Oracle塊級別的備份根據(jù)需要快速創(chuàng)建完全虛擬備份具温。
Multiple client databases—known as protected databases—share a single, centrallymanaged Recovery Appliance catalog that resides on the Recovery Appliance. All protected databases that send backups to Recovery Appliance must use this catalog.Virtual private catalog technology enforces separation of duties among the protected database DBAs and the Recovery Appliance administrator.
多個客戶端數(shù)據(jù)庫（稱為受保護的數(shù)據(jù)庫）共享位于恢復設備上的單個集中管理的恢復應用裝置目錄蚕涤。 將備份發(fā)送到恢復一體機的所有受保護的數(shù)據(jù)庫必須使用此目錄。虛擬專用目錄技術強制在受保護的數(shù)據(jù)庫DBA和恢復一體機管理員之間分擔責任铣猩。
Real-time redo transport minimizes the window of potential data loss that exists
between successive archived log backups. Redo data from the protected database is
written directly to the recovery appliance as it is generated.
實時重做傳輸將存在的潛在數(shù)據(jù)丟失的窗口最小化在連續(xù)的歸檔日志備份之間揖铜。 從受保護的數(shù)據(jù)庫重做數(shù)據(jù)是在生成恢復設備時直接寫入恢復設備。
Recovery Appliance is integrated with Cloud Control and RMAN. An accompanying
media management library is used for communication between RMAN and Recovery
Appliance. Cloud Control enables administrators to centrally manage and monitor the
data protection of all protected databases in the enterprise.
恢復設備與云控制和RMAN集成达皿。 伴隨補充的介質(zhì)管理庫用于RMAN和Recovery之間的通信天吓。 云控制使管理員能夠集中管理和監(jiān)控企業(yè)中所有受保護數(shù)據(jù)庫的數(shù)據(jù)保護贿肩。
Oracle Secure Backup, the tape management component of Recovery Appliance, is
preinstalled on Recovery Appliance. For disaster recovery, Recovery Appliance can
replicate backups to other Recovery Appliances. A single Recovery Appliance can
service multiple protected databases of different versions and from different
platforms.
恢復設備的磁帶管理組件Oracle Secure Backup是預先安裝在恢復設備上。 對于災難恢復龄寞，恢復設備可以將備份復制到其他恢復設備汰规。 單個恢復設備可以服務不同版本和不同的多個受保護的數(shù)據(jù)庫平臺。
Using RMAN with Recovery Appliance
You can use most RMAN commands to back up to and recover from Zero Data Loss Recovery Appliance (Recovery Appliance).The following sections provide additional information about using RMAN with Recovery Appliance:
? “About RMAN in a Recovery Appliance Environment”
? “Configuring RMAN to Make Backups to Recovery Appliance”
? “Unregistering a Target Database in a Recovery Appliance Environment”
? “About Real-Time Redo Transport for Recovery Appliance”
? “About the Incremental-Forever Backup Strategy for Recovery Appliance”
您可以使用大多數(shù)RMAN命令備份和恢復從零數(shù)據(jù)丟失恢復設備（恢復設備）物邑。以下部分提供有關使用RMAN及恢復設備的其他信息：
