don't see that option.
on the devices tab, i right click the folder and choose properties, on the general tab i see:
maximum size for backup to disk files
allow 6 concurrent jobs for this backup to disk folder.
on the advanced tab, i see:
low disk space threshold
auto detect settings.
do not see maximum number of backup sets per backup to disk file.
if i go through the menu, tools/optionsbackup-to-diskf folder, i see the option and it's set to 100 for the application defaults.
so, i deleted my folder and created a new one and the option is there now. have no idea why it was missing.
thanks, we'll see if it works now.
