Sorry for the delay in responding. I've been collecting my thoughts. I have a few questions left about your configuration.
I'm just going to ask what you meant in a few cases. It has nothing to do with your accuracy, just what you meant.
You said that your file server is running Xandros Linux.
The backup machine has the following configuration: "XP, 2.4 ghz, 516 256 ram". I read that as follows: AMD Athlon XP 2400+ 2.4 GHz, 516 ?????, 256 MB RAM. Is this a correct understanding of what you wrote?
You also said that no other backups were being performed but you also said that .pst files are being backed up from other clients. I read that as meaning that .pst files are being backed up from desktop machines. Is that correct?
You say that your network protocol is p2p. Do you mean Microsnot Windows networking in workgroup mode?
You refer to the backup server as a client of the Xandros file server. Do you mean that the Xandros file server is running Samba and the backup machine mounts a share to perform the backups? Is this also true about backup up the pst files from the desktop machines?
You said that you are using Veritas Backup Exec V5.0. Do you mean that you are using the Backup Exec that comes free with some DVD-RW drives such as Sony DVD-RW drives?
My overall impression of your configuration is as follows:
Xandros Linux file server using Samba to share files in Microsnot Network running in workgroup mode.
File server running ? operating system and Backup Exec for workstations/personal/home use.
Several desktop computers sharing the disk/folder containing their Outlook pst files.
Is this correct?
Are you running TCP/IP protocol? If you are and you have no DNS then either you are running WINS or you have a complete hosts file on each machine. Is this correct? If so which/both?
Your p2p networking isn't something like Kazaa is it?
Again, I'm sorry that I kept you waiting. I'm just trying to understand the problem.
Cheers. :-)
