Exact Error Message
 
snapshot error encountered (156)
 
 
Troubleshooting:
 
If a backup of a Windows NetBackup (tm) client fails with status code 156, this indicates that the client is using Windows Open File Backups to protect open or active files. The volume "snapshot" that occurs to facilitate open file backup has failed. This failure is often caused by the VSS cache file running out of allocated space.

Resolution:
 
For Volume Shadow Copy (VSS) (Windows 2003 and later only) use the following steps to increase the cache size when VSS is used on Windows clients:
 
1. In Windows, double-click My Computer and select The drive being backed up (i.e. D:/)
2. Right mouse click on the drive and click Properties, select Shadow Copies.
3. Select the volume on which to make changes, and then click the Settings button
4. In the Settings dialog box, change the Maximum Size setting to either No Limit or a size large enough to suit the requirements of the installation and usage of VSS
 
Refer to VSS configuration procedure described in http://www.veritas.com/docs/000011553
