Backup of large disks with BackupExec

Hi

I have upgraded to Backup Exec 2012 and want to backup a file server. Disk to disk.

The amount of data I need to have backed up will vary between 8 og18 TB.

My backup server has 24TB capacity. As I understand it is recommended to use the full backup and incremental in a cycle.

Because of the amount of data, I would never get the opportunity to have two simultaneous full backups on the backup server. To delete a full backup to make room for a new full backup means that the data will be unsecured the time it takes to make a new full backup. Not a good solution.

 

What is the best practice?

My goal is daily backup of the file server and keep the data three months after the original files have been deleted from the file server.

Should I have an other version of BackupExec? Have previously used BE Continuous Protection Server.

 

Suggestions received with great thanks
