which is beter to backup SQL 2008
i have 2 databases one is 500GB and the second is 800GB
i have backupexec 2010 with the sql agent installed on my network
 is it better to use traditional sql backup
1 full wkly
1 DIFF DAILY
TRANSACTION LOG FILES EVERY 15 MINUTES
then backup to tape nightly\weekly using backupexec

or use bacjup exec to do the backups directly
i dont see any option to do this with backup exec, i dont see an option to do full\fiff and transactions logs

also the backupexec sql agent says it does Continuous data protection for SQL
Server i, i do not see this option

I would go with the full backups weekly and daily differentials
You can space out your transaction log backups according to how frequently the data is modified

Weekly Full BAckup
Daily differentail backup and 15 min transacrtion backup is the right way, but please check the Performance of your Drive,
Disk Performance can be checked by using SQLIO , a Freeware SAN Drive benchmarking tool

First consider like if your database is LEVEL1 then go for Daily Full Backup and for every 15mins transactional backup.

If the database is below LEVEL1 grade then go for weekly full backup and daily differential backup, transactional backup for every 30 mins is enough as mentioned above.

But consider the data (importance) critical\loss would you can accept. I recommend to first option as to Backup DB Daily and for every 15 mins tansactional backup.
