Re: A different way to create and email avamar reports.
why could you not have performed these various commands and renaming etc. on the Utility node then email them directly from it?
As an intermediate option, have you looked into "plink" or its more GUI-friendly cousin TortoisePlink.exe? The plink utility can be used to run SSH commands on remote hosts and it's a lot more lightweight than WinSCP.
For the security conscious, I would recommend setting up passwordless authentication from the Windows host to the utility node. While this is not officially supported, it does work and it's far more secure than saving login credentials. This does require you to keep the private key secured.
