Backup online VM's only

Sep 23, 2016 at 11:52 AM

Is there any option or possible to backup online VM's only, instead of provide a list of names?

one more query,
I have 12 VM's and i run the script with "HVBackup.exe -a -o \server\e$\Backup\HV_Backup" it takes 2 days for backup, after backup size of zips are 517GB. why it takes long time over network?
