SAP Backup and Recovery Techniques: A Complete Guide
SAP Backup and Recovery Techniques: A Complete Guide
Data loss, corruption, or system failure can disrupt
business operations at any scale. That's why SAP backup and recovery
techniques are not just best practices—they're critical pillars of enterprise
data management. Whether you're a student learning SAP Basis, a job seeker
preparing for technical interviews, or a system admin in charge of IT
infrastructure, mastering SAP database backup and recovery processes is
essential.
This guide covers various SAP HANA, SAP NetWeaver,
and SAP ECC backup strategies and disaster recovery (DR) planning.
What is SAP Backup and Recovery?
Backup refers to creating copies of SAP data,
configurations, and logs to safeguard against loss. Recovery involves
restoring that data to return the system to a consistent operational state.
In an SAP landscape, backup and recovery processes are tied
closely to the database platform (HANA, Oracle, MaxDB, etc.) and system
architecture.
Why SAP Backup and Recovery is Important
- Prevent
data loss during hardware failure
- Protect
business-critical applications
- Restore
systems quickly during cyberattacks
- Comply
with regulatory requirements
- Support
high availability and business continuity
Types of SAP Backups
1. Database Backups
Performed at the database level, these are essential for
data consistency.
- Full
Backup – Backs up the entire database
- Incremental
Backup – Captures changes since the last backup
- Differential
Backup – Backs up changes since the last full backup
- Log
Backup – Captures database transaction logs
What is SAP Landscape?
2. File System Backups
Used for SAP kernel, profiles, and OS-level configurations.
Recommended to complement DB backups.
3. SAP HANA Backups
SAP HANA supports both file-based and storage
snapshot-based backups using tools like:
- SAP
HANA Studio
- SAP
HANA Cockpit
- Backint
for SAP HANA
4. Configuration Backups
Includes backup of SAP profiles, transport directories,
custom code (Z-programs), etc.
