We are currently looking at building out our Data Center to support a managed backup solution for multiple clients. We are currently looking at pushing the backups through a pair of ASA5580-20 appliances, however I have concerns as I haven't had much success with backups through a firewall in the past (albeit much smaller firewalls). Has anyone/Is anyone doing this now? Do you current see any performance degradation? What platform are you using? Thanks for your help.
