Error description
The Tivoli Storage Manager server displays high CPU load and high mutex locking during Windows 2008 systemstate backups. Tivoli Storage Manager client progressive systemstate backups on Windows 2008 are very slow with an extremely low aggregate data transfer rate. No issue is seen with filesystem incremental backup. Tivoli Storage Manager Versions Affected: all Customer/L2 Diagnostics: Tivoli Storage Manager client instrumentation trace (testflag instrument:detail) of the Windows 2008 systemstate backup shows that almost all time is spent in category "Other". Client trace (traceflag service) shows that an excessive amount of time is spent getting the list of files from the server belonging to previous systemstate backup (function PrivObjEnumBack) and reassigning objects from the old group to the new group (function baAssignObjsToGroup). Both functions work as designed. Server trace with flags "session group delta back backd" will show slow downs in the server grouping code. Initial Impact: Medium
