Error description

  • FlashCopy Manager for Exchange Differential and Incremental
    backups are not marked as inactive after a FULL backup when
    /BACKUPDESTination=BOTH is used.
    .
    Backup objects may not be marked as inactive when using
    /BACKUPDESTination=BOTH for Differential and Incremental backups
    after a FULL Backup is performed. The steps to recreate this
    scenario are:
    .
    1) Perform a FULL VSS backup of an Exchange storage group
    (Exchange 2003, 2007) or Exchange Database (Exchange 2010)
    .
    2) Perform Differential VSS backup of the same Exchange storage
    group/Database with the Backup Destination defined as BOTH
    .
    3) Perform another Differential VSS backup of the same Exchange
    storage group/Database  with the Backup Destination defined as
    BOTH
         --> At this point: #2 should be marked as Inactive
    .
    4) Perform a FULL VSS backup of the same Exchange storage
    group/Database
        --> At this point: #1, #2, and #3 should be marked as
    Inactive
    .
    Platforms affected:  All FlashCopy Manager for Exchange
    and Data Protection for Exchange environments.
    .
    Initial Impact: Medium
    .
    Local Fix: None.

Problem conclusion

Temporary fix

Comments

  • ****************************************************************
    PROBLEM CONCLUSION:
    Before applying this fix, Incremental and / or Differential
    backups created using the /BACKUPDESTination=BOTH option are not
    properly versioned after a FULL backup because the backups older
    than the most recent backup are not marked as inactive.
    Therefore over time, it is possible to run out of storage space
    in the location designated for storing backups (TSM or local)
    because inactive backup versions are never expired / deleted
    once reaching the retention values defined for your environment.
    .
    The fix for this APAR has modified the code so that Incremental
    and Differential backups are correctly marked as inactive and
    processed for deletion from storage.
    .
    After applying the fix, any Differential and / or Incremental
    backups that were incorrectly left in the active state will be
    inactivated correctly once a new FULL backup is performed.
    .
    Depending on the number of inactive backups, the first
    expiration performed could take longer than what is usually
    seen for your environment.
