exact copy backup
I am new using Symantec Backup exec.
I have Backup Exec 12.5 and I would like to backup my file server (300GB) to an external hard drive located in another building. I setup it up and it is working. However, I setup it up using the differential backup and each night it backs up only the files that have been changed from the last time of backup. The problem that I am experiencing is that my backup media (external hard drive) is filling up quickly.
Is there an option to have an exact backup of the server? Meaning, if a file has been modified, it just replaces the backup copy on the external hard drive, instead of backing up another copy of the same file.
I would like to avoid having to do a full backup each time, as it takes so much time to backup my server.
I am running Windows Server 2008 - 64 bit
Thanks for all your help. Blessings, Steve
