We are a private school. We had been running Retrospect 6 for years. We migrated to 8 this winter. We are running it on the same type of machine we run 6 on- an original, non-Intel 1.33 GHz Xserve with 2 GB of RAM. The network is exactly the same; we didn't change anything.
Restrospect 8 runs so slowly that it is unusable. A client with 1 GB of data takes hours to back up. Looking over the console, backup speeds range from to 409 KB to 16.4 MB per minute. In contrast, our still-running Retrospect 6 server averages 300-600 MB/min- with an identical server, running on the same network.
Any ideas on why it runs so slowly, and what we can do to speed it up?
