Database Backup

I was taking backup of my databases using veritas. I got following errors. Does anyone know how can I fix these?
Thanks

Quite possible.. Could you tell me what would be the better way of taking backup. Additionaly, do I need to take the backup of the system databases.|||Originally posted by rnealejr
What version of veritas are you using ?

version 8|||Are you attempting to backup the logs on these databases ? If so, if your recovery model is simple - the log file cannot be backed up. Also, in veritas, did you select the database to backup or the filegroups ?
