The content of this presentation is about backing up to Cloud Storage from on-premises or from cloud instances via RMAN or from ZDLRA “Archive to Cloud”.

RMAN: Built-in backup &
recovery engine for the Oracle
database which provides
performant, efficient
and dependable protection.
Recovery Appliance:
Engineered System purpose-
built for data center-wide Oracle
database protection which
ensures zero data loss, verifies
backup integrity, and reduces
data protection overhead by
eliminating repeated full
backups.
DB Backup Cloud Service:
Secure & scalable Oracle Cloud
Service providing cost effective
storage for long-term retention
& compliance of RMAN
backups.
Secure Backup: Centralized
disk, tape and cloud backup
management which provides
heterogeneous filesystem
protection for the entire data
center.

29. Why backups in the Cloud?
Requirements to keep backups offsite
Security and Compliance
Cost savings
Who is doing backups in the Cloud?
City of Las Vegas (Public Sector)
University of Colorado (Higher Education)
i-wireless (Commercial)
Many others, including well-known name brands.
30. Pre-Implementation Considerations
• Retention and Storage Requirements (Archive / Object)
• Region Designation (Region Replication)
• Network bandwidth requirements and capabilities
• Dev / Test Cloning Requirements
• Security and Access Management (Compartments, Roles, Buckets, etc.)
• Backup tool (existing / new)
• Good news: All your existing RMAN know-how is still very applicable
31. Lessons Learned
• Re-use existing backup scripts to save time
• Test Full Backups and Incremental Backups (adjust backup windows)
• Measure and Tune for Performance
Degree of parallelism, including intra data file parallelism # of channels
Block Change Tracking
FastConnect Considerations
• Set the base line using RMAN NETTEST
run {
allocate channel c1 device type sbt PARMS ‘sbt_library=libopc.so’;
send channel c1 ‘NETTEST BACKUP 1024 M’; }
• Use LOW or MEDIUM compression
For more details on NETTEST see: “How to measure network performance from RMAN for ZDLRA or Cloud Backups (Doc ID 2371860.1)”
32. More Lessons Learned
• Test Restores and Cloning
• Keep or Delete Archive logs
• Use AES-256 as your standard
• Ensure encryption wallets are backed up
We recommend storing on offline media in a safe location
