Backups intermittently hang at 95% and show a status of 'Updating history' (Figure 1).

Figure 1:


This typically occurs when multiple machines are backing up to the same backup destination folder (i.e. a network share, NAS device etc).


The current workaround is to unregister RPAM (RPAM.DLL) on each machine that is affected by this issue:

RegSVR32.exe /U C:\Program Files\Common Files\Symantec Shared\rpAccess\Rpam.dll

NOTE 1: Once RPAM.DLL is unregistered, the machine in question will lose the ability to mount recovery points. This includes the ability to open recovery points using the Granular Restore Option (GRO). If mounting is required, re-register the DLL using the following command:

RegSVR32.exe C:\Program Files\Common Files\Symantec Shared\rpAccess\Rpam.dll

NOTE 2: You must stop the Backup Exec System Recovery service before unregistering RPAM.DLL. The service can be restarted once the command has completed successfully.
