How can your backup architecture keep you protected as your data grows?


The challenges of backing up large databases

Technical Factors Customer Constraints

• Long backup & restore times

• Application impact

• Architectural complexity

• Storage requirements

• Database compression

• Short backup windows, tight SLA

• Application uptime

• Ease of use

• Storage budget pressure

• Database encryption requirements


Snapshots are not backups Snapshots have their place, but don’t replace a full backup

Production DB server

STD snapshot

Backup software Backup Storage

Mount server Snapshot drawbacks

❌ Consume primary storage space

❌ Can’t protect against disk failures

❌ Low application impact, but other issues – Management overhead – What about LTR? DR?

❌ Backup time includes snapshot time + backup time from mount server • Snapshot can be mounted on an alternate server

• Offloads impact of backup processing on DB server & primary storage


Large databases challenge traditional backup software

❌ Application impact - all data passes through application server

❌ Missing SLAs (RPO/RTO) – A lot more data to move – Complex data path

❌ Complex and Expensive – Needs more backup or media servers – More network connections – Infrastructure required to meet SLA

continues to grow

❌ Management are shared

Best dedupe rate for Oracle Using Data Domain’s Oracle optimization parameter

• Oracle multiplexing reduces effectiveness of other deduplication appliances except Data Domain

• Understands Oracle’s backupset data structure

• Result: 30% increase in deduplication

• Highest dedupe rates of any dedupe appliance.

Oracle Transparent Database Encryption (TDE)

• Increasing adoption of database encryption

• RMAN encryption not needed -encrypted data is backed up

• Data Domain still dedupes this data because encrypted data doesn’t change till updated

• TDE consumes more backup storage because encrypted data cannot be compressed

Oracle database encryption (Vormetric)

• Encryption management is a nightmare without centralized key management

• Increasing adoption of enterprise level encryption software like Vormetric

• Backup data are unencrypted on server first

• RMAN encryption is not recommended with Data Domain.

• Data Domain have encryption in flight and encryption at rest

DB2 shared-nothing architecture for scalability DB2 Data Partition Function (DPF)

Shared nothing DB2 database via Hash Partitions • Database is divided into multiple partitions • Partitions run on different servers • Each partition has balanced resources • Parallel processing occurs on all partitions and is coordinated by the DBMS • Single database system image to user, DBA and application

Best dedupe rate for DB2

• Multiplexing - DB2 multiplexes by reading data from

several tablespaces simultaneously

• DD Boost DB2 integration - No performance impact from DB2

multiplexing - Great dedupe rate without DB2 backup

parameter “dedupe_device” - Dedupe_device reduces the backup

performance when there are only few large tablespaces

DB2 native encryption • DB2 has two different processes to

encrypt data and backup data: • DB2 native encryption can encrypt the

database and send encrypted or unencrypted backup data to backup storage

• Data Domain supports DB2 database encryption and unencrypted DB2 backup

• Data Domain offers encryption in flight and encryption at rest

• Disable DB2 backup encryption - Change DB2 database config parameters

“ENCRLIB” and “ENCROPTS” to null - Make sure DB2 backup script don’t encrypt

Backup

Backup/Restore using HANA’s backup API - Backint • Full support of Backint – SAP API for backup agents • Performance: backups transferred via named pipes

Log Backups • Save redo log entries contained in the log area • Log Backups are carried out automatically

SAP-Certified Backint integration


SAP HANA Backup and Recovery Improved performance: Backint now uses parallel streams for data backups

To configure the number of parallel streams, use the parallel_data_backup_backint_channels ini file parameter (default: 1, max: 32). Same number of streams used is the same during recovery (independent of the current setting of the parameter)

Parallel streaming: • Individual backups distributed across available streams • Used for both full & delta backups • Must be 128GB or larger to distribute
