Question : Problem: backup exec 11d   sharepoint 2007

Hi, i notice agents and a lot of third party tools suggested for backing up sharepoint

what are you missing out on by just using backupexec 11d? with out the sharepoint add on.

Answer : Problem: backup exec 11d   sharepoint 2007

i've heard of issues with backupexec conflicting with sharepoint.  (just google "sharepoint backupexec problems")

however, just as a note... there is no need for a special program or utility for sharepoint backup.  both SQL and sharepoint have sufficient backup ability built-in.
for SQL, just log into sql management studio and schedule a backup of your sharepoint databases.  

for sharepoint, you can use a simple batch file to run a backup.  the batch file just calls stsadm, which is a tool that comes with sharepoint.
here is an example of this kind of backup script:

people have even written handy scripts that have even more features.
see here for SPS 2003 script: http://steve.wedevelop.net/archives/000307.html
this is the one that i use: http://www.networkworld.com/community/node/18202  (it emails a log to me)

i have used that script to backup AND RESTORE my wss 3.0 site, so i know it works.  to restore, i installed the sharepoint application on a new server, and then used the restore wizard in central admin.

i do both... i use the stsadm script, and i also run a backup using the sql agent in sql mangement studio.  you don't need to do both, but it would give you two different ways to restore a sharepoint site in case of disaster.
