I spent the last week building a backup server with WINDOWS 2008 and BACKUP EXEC 2010. With advice from here, I finally got it running the way I want it to. In reviewing all the servers that need to be backed up, i found that another servers previously had BACKUP EXEC 12 installed on it, but we no longer use it as a backup server. When my current FULL backup completes, I get an exception "the target computer is running a previous version of Backup Exec remote agent, you must upgrade the remote agent"
I recall when using BACKUP EXEC 6 or 7 back in the old days there was something called an accelerator that had to be installed on each server. Is this the same thing? What is the best way to handle this, remove the old agent from the old server or try to upgrade it?
