NetBackup status code: 4251
Explanation: Error occurred on media server while writing into index database.
Recommended Action: Typically, the index database is created under NB_INSTALL_DIR/tmp; for example, /usr/openv/netbackup/tmp. It can be overridden by SNAPDIFF_DB_PATH in the NetBackup configuration file. Ensure that there is enough space on the media server to create the index database. Check the NetBackup administration logs for more details.
