在Debian系統上恢復Oracle數據庫數據主要依賴于Oracle提供的RMAN（Recovery Manager）工具。以下是一個基本的備份和恢復流程：
rman target /rman backup database format '/path/to/backup/full_backup_%U'
rman target /rman backup incrementally database tag '增量備份標簽' format '/path/to/backup/incremental_backup_%U'
rman target /rman backup archivelog all format '/path/to/backup/archivelog_%U'
rman target /restore database
rman target /restore database with recovery
rman target /recover database with recovery
rman target /restore controlfile
sqlplus / as sysdba startup
