On a SBS 2003 server I use its built-in backup utility to backup everything, including Exchange.
Last time a 400 GB backup took 12 hours, plus more for verification - total was 18 hours.
Machine is a 3.0 GHz, 4 GB RAM. Backup device is an external hard drive USB 2.0 connected directly to the server.
Is this a normal backup time? If not, what am I doing wrong? I used SBS install settings and backup settings that are pretty standard, or so I think I did it...
