Backups of System Reserved partition intermittently hang at 5% when using Symantec System Recovery (SSR).
When this issue occurs, VProSvc.exe takes up around 50% CPU.
The issue is seen when backing up to a network location (i.e. network share) but has also been seen when backup destination is set to a local device (i.e. USB drive).
NOTE: When the issue occurs, end the process for VProSvc.exe in Task Manager which will cancel the active backup and return the CPU level back to an acceptable level.
This issue is resolved in service pack 3 (10.0.3) for SSR 2011 which is available via LiveUpdate, MyVeritas portal (See http://www.veritas.com/docs/000100418) and here http://www.symantec.com/docs/TECH195461.
