BACKUP PLAN

Im running a client server network with over 100 clients.The server is windows 2003 server and the workstations are XP and 2000 proffesional.
-I need a backup plan that will be able to backup outlook pst files and large amount of user files from the active directory.
-The backup should be done in the server and a copy also made to an external terabyte hard disk connected over the network.
-i should be able to do a restore from the copy in the terabyte HardDisk.
Any suggestions and solutions will be highly appreciated.

Do you use Exchange Server?

No exchange server.Im using maildaemon instead.

What do you mean by this?

... large amount of user files from the active directory.

Are the pst files located on the users' machines?

The pst files are on the user machines and they do occupy alot of space.This contribute to the large amount of user files from the workstations.I meant workstations not Active Directory.

Because of the files located on the user machines, you will need to use a solution that supports agents running on the client machines. Veritas Backup Exec will do the job easily. I've used it for years and it's very good.

One suggestion, especially if you use Outlook on the clients would be to use Exchange, as this would enable you to consolidate all your email data in one place and more importantly control the size of your users' mailboxes and thus the size of your backups.
