Error description

  • Incremental backups of Tivoli Storage Manager clients can take
    significantly longer (or hang) after updating the Tivoli Storage
    Manager server to version 6.1. Additionally the clients will
    show a very high memory consumption during the incremental
    backup and the client session does only transfer a small amount
    of data.
    .
    The symptoms are similar to those described in APAR IC65323
    which describes backup performance degradation when backing up
    to disk storage pools with caching enabled. While APAR IC65323
    only applies to Tivoli Storage Manager 6.1.3, the symptoms of
    this APAR can be observed with all Tivoli Storage Manager server
    levels 6.1 on all platforms, regardless if caching is used or
    not.
    .
    Versions Affected:
    Tivoli Storage Manager 6.1.3
    .
    Customer/L2 Diagnostics (If Applicable)
    The symptoms are most likely seen on filesystems with a large
    amount of objects
    .
    Initial Impact: High
    .
    Additional Keywords:
