Hi Expert,

I trying to take my Sybase database backup into network shared through below Sybase isql command.

dump tran <database name> to <network location> <file name>

example.

dump tran PRD to '\\192.168.1.3\prd_bkp\PRD_backup_sybase_log\PRD_10102014_1053.dump'

but backup failed with below error.

Backup Server session id is: 142. Use this value when executing the

'sp_volchanged' system stored procedure after fulfilling any volume change

request from the Backup Server.
