Optimize backups for data deduplication If your storage manager is enabled for data deduplication, use the IFX_BAR_USE_DEDUP environment variable to make backup operations more efficient. The new environment variable optimizes the format of backup images for deduplication processes.	IFX_BAR_USE_DEDUP environment variable
Enhanced support for IBM® Tivoli® Storage Manager features If you use IBM Tivoli Storage Manager with the ON-Bar utility to back up and restore data, you can configure ON-Bar to support the following Spectrum Protect features: You can speed back up and restore processes by setting a longer transfer buffer size. Set the IFX_BAR_NO_LONG_BUFFERS environment variable to prevent long transfer buffers. You can replicate or import and export backup objects between Spectrum Protect servers. Set the IFX_TSM_OBJINFO_OFF environment variable to prevent this feature.	Configuring ON-Bar for optional Spectrum Protect features
ON-Bar activity log timestamps When a storage manager process hangs, the timestamp for the process in the ON-Bar activity log is inaccurate. The inaccurate timestamp represents the time at which the storage manager process started hanging instead of the current time. Inaccurate timestamps in the ON-Bar activity log are identified with an asterisk. The accompanying message lists the number of minutes after the timestamp that the storage manager process hung.
