In our environment we've installed a Cisco ASA5510 FW. Inside the FW we've a W2003 Backupserver running Backup Exec 10.0. In the DMZ of the FW we've placed a W2K webserver. Currently we experiencing intermittent problems regarding the backup.
- The backup can run smoothly for several days and the without any warning and pattern (none as far as we've figured out) the backup begins to fail. The amount of data and time before it fails varies.
- A simple change in the backup job will correct the problem for another couple of days. For instance change NIC.
- We've followed the recommendations from Veritas with regard what ports needs to be open. Netstat verifes that the connections succeds.
- Debugging logging of the FW is inconclusive. The logs shows a reset-o.
Has anyone experienced this kinds of problems before? We're seriuosly contemplating switching to just create a VMWare script and get the backup out that way, but it will cause slower restore time in case we need to restore single files.
