  • HANA Streamed Backup Approach

    2014 NetApp, Inc. All rights reserved. NetApp Proprietary Limited Use Only 6

    HANA Studio triggers a global synchronized backup save point

    HANA Backup stream can be

    directly written to disk

    send to a backup server using SAP HANA backint interface

    Challenges

    Long backup operation

    Performance impact during backup operation

    Slow restore and recovery

    Option 1:

    Backup to disk

    Option 2:

    Backup with Backint
