SAP HANA Database Backup and Recovery (New and Changed)
Enhancements for Log Backups
Using SAP HANA, all the log segments of a service, which are ready to be backed up at the same time, can be written to a single log backup to improve performance. For each log backup, you can specify a maximum file size.
As well as file-based log backups, third-party tools also support this option for log backups.
Details: Writing Multiple Log Segments to a Single Log Backup.
Log backups can be triggered by events in SAP HANA 2.0.
By default, a log backup is created as soon as a log segment fills up, or when the service-specific timeout for a log segment has been reached for that segment.
A log backup can also be specified to be created only if a service-specific timeout has been reached, if you prefer that option.
As well as file-based log backups, third-party tools also support this option for log backups.

Encryption and Backup and Recovery
Data encryption is supported in SAP HANA 2.0's persistence layer.
When it comes to encryption root keys, the database administrator must make sure they've been copied and stored somewhere safe. It's important for a database administrator to import the root keys before performing a recovery.
There is more information on the website: Notables: SAP HANA Backups and Encryption, Root Key Backup, and Import Backed-up Root Keys in Related Information.
Location of the Backups of the Backup Catalog
Unlike the backup catalogue, the location of log backups is configured separately.
To recover SAP HANA, you must specify the path to the backup catalogue before you can proceed.

SAP HANA Multitenant Database Containers
Using a data backup of a SAP HANA single-container system, it is now possible to restore a tenant database from a SAP HANA backup.
There is more information on the website: When copying a database with Backup and Recovery, Please take note of the following: SAP HANA Multitenant Database Containers & Backup, SAP HANA Multitenant Database Containers and Recovery in Related Information are important to note.
Extension Node for Business Warehouse
With SAP HANA 2.0, the extension node for Business Warehouse can be used to recover the database.

SAP HANA on IBM Power Systems: Release Compatibility
Only IBM Power Little Endian (LE) systems are supported by SAP HANA 2.0.
SAP HANA 2.0 backups are compatible with both supported hardware platforms (Intel and IBM Power). It is possible to restore SAP HANA 2.0 from backups created with SAP HANA 2.0 on either an Intel-based or an IBM Power-based platform.
You can restore SAP HANA 2.0 to both Intel-based and IBM Power-based systems using backups created with SAP HANA 1.0 SPS 10 or later running on an Intel-based system. IBM Power-based backups created with SAP HANA 1.0 cannot be used to restore SAP HANA 2.0.

SAP HANA Cockpit (Changed)
It's now possible to use a new and improved SAP HANA cockpit.
With the change to the SAP HANA recovery and backup procedures using SAP HANA cockpit, the guide has been updated.
