    I just purchased a HP EX475 media server and upgraded the ram to 2GB, also installed two new 1tb hard drives.  I have configured my network with three computers to backup to the server.  One has about 600gb of data the other only about 10gb each.

    I start the back process and it runs fairly quickly to the file transfer stage, 58%, and then just runs so slow it is worthless.  It has run of over 8 hours and only reached 71%.  I realize this is the first backup of th esystem but this just doesn't seem right.  It slows th ewhole network to a crawl and I can see it transfering data over the router, but why is this so slow?  I really installed to mostly to use as an automated network backup but maybe I need to do that another way.

    Any help advice would be appreciated.

    The first backup, of the first computer, may take quite a long time (possibly many hours if you're backing up the one with 600 GB of data first). This is because each cluster of data on the computer has to be transferred to the server and stored in the backup database. Exact speed is dependent on many factors: your network infrastructure, what else is running on the computer being backed up, drivers and NIC hardware, etc. Subsequent backups of that computer, and backups of other computers, should be significantly faster, however; the backup tool uses a concept similar to Single Instance Storage, except at the cluster level, to store only a single instance of each unique cluster in the database.

    You may want to take a look at the Home Computer Backup technical brief for more information.
