How fast does Backup for Workgroups backup data?
The answer depends upon the following: (1) the speed of the hard drive that is being backed up, (2) the speed of the CPU of this computer, (3) the speed of the network connection between the computer getting backed up and the Data Repository Manager, (4) the CPU speed of the Data Repository Manager computer, and (5) the speed of the hard drive holding the backup data. Generally speaking, you should see backup speeds on average Windows computers in the range of 200 – 400 MB per minute. You will notice an increase in speed on large files and a decrease in speed on lots of spread out, little files because some of the backup time is spent looking for files to backup. The more files that are identified for backup means more time spent during the backup process. Just to give you an example from Lockstep’s lab, an Exchange 2007 Server with a 2.4GHz CPU backs up at the rate of 350MB per minute over a 1-GB network connection. This is backing up to a slightly slower computer used as a Data Repos
