I was one of the unfortunate admins who chose to perform routine server maintenance on our Exchange server on a day when Microsoft accidentally&nbsp;released a pre-release&nbsp;rollup 4 package via Windows Update. &nbsp;I currently have exchange version 8.1.311.1, which is Exchange 2007 SP1 with Rollup 4. &nbsp;We have a few Symantec Backup Exec 12 problems which I have read are caused by this rollup.

My question is can I install the Rollup 4 version 2 over top of rollup 4 version 1? Or should I uninstall the version 1 rollup and then install the version 2 rollup.

Exchange 2007 SP1 Rollup 4 Question

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
