Performing file backups to another AIX server or Windows server

[jjjtech]

We have three systems using three different AIX boxes. All are currently performing their backups to DATs. I have an F30 that was taken out of service over a year ago with a clear AIX license on it (I think v4.3.3). What I would like to do is perform all of the backups on the AIX boxes currently in use to the old F30 or a Win2K server, whichever would be easier/quicker.
I tried something along this line a while ago. One of our vendors send the backup to a temp file while the application is offline, then brings the app back up and dumps the backup to DAT. So I did an FTP of this file to a Windows box. Since the file is anywhere from 3GB to 7.5GB the process took upwards to 20 hours to do. No good.
We are looking to eliminate the daily tape changes and still maintain data.
Any suggestions?
Thanks.

Hello,
we do the following for all our mksysb (6 serveurs) :
One server has a /backup filesystem that can be export by NFS on the other server. The others servers perform there mksysb on this Filesystem by mounting it with automount.
This is done really quickly (about +- 2 hour) and some of thi mksysb are greater than 2gb.
I can put the script i'm using for doing this... if you want!

Still going to have server network bandwitch time using NFS or Samba.

LeDam- I would love to see the script for this. Thanks.
dblair- most of our network it at least 100bit and a good share of that is being/has been upgraded to 1Gb. However there is always room for improvement.
