Backup Exec RALUS Add-on [13.0.5204.1]

Hi. My setup is agent 12.5 and backupexec 13.0.5204.1. Try using the old agent instead of the new one. For now everything seems to be working fine but the job rate is now a half of what it was used to be. Its taking more time to complete the backups, to be more specific, the double of time. A few months ago we were using a windows server to store the files and then we used the backupexec to make the backups from there. Now we have migrated all the data to the readynas using the 12.5 agent. Since then, the backup times have increased. I think that this performance issue could be corrected using the new agent but that was the issue at the beginning. If we try to use the new agent it wont show up in the selection tree in backupexec. So I have two options: install the new agent and wait for the backupexec to see the server or keep using the old one but experiencing performance issues. Not to mention that support from the manufacturer is below my expectations.
