Hello,
the most used way to monitor jobs running at different sites is to use the email notifications which you can set up on the Program Settings dialog. You could use a mail filter to have them moved to a special folder in your email client and at the end of the day, you just need to count the emails to check if they match the number of customers, and mark them as read.
Another way would be in the GUI under File->Monitoring tool, but this only works on the LAN or over a VPN. It requires that you can access the remote machine in Windows Explorer with UNC paths such as \\blabla.dyndns.org or \\123.234.123.24.
2. What are the best settings in SFFS for the fastest file transfer?
Usually FTP library number 3 has the highest transfer rates. In addition, you will want to copy several files in parallel. The number can be specified on the Files tab sheet.
3. Are there any best practices to insure the reliability of the backups...I have had a situation where the Scheduler stopped running.
It is probably best to install the scheduler as a service. Please see
