Sometimes when I try deleting an existing backup schedule, it takes a lot of time. Why is this?

While deleting a backup, Giga Vault Storage tries to connect to the server machine to delete the backed up data. So, please verify that the server machine is accessible from the client machine and that Giga Vault Storage is running on the Server machine in "Server/ Server-Client" mode. The delete operation will be scheduled every 5 minutes. If a backup could not be deleted because of some reason (the backup server being down permanently, etc.) then the delete operation will be rescheduled every5 minutes. There is no way to cancel the delete operation. It will be scheduled again even when Giga Vault Storage is stopped and restarted. Hence, ideally, Giga Vault Storage must be running on the server machine for completing the backup delete schedule. In a 'not so ideal' situation, you could use the "Delete Backup Schedule even if the server is down" option from the "Delete Backup Data/Schedule" page. The backup configuration will be deleted from the client side in the next delete schedule, ie about 5 minutes. Please note that the backed up data in server might not be deleted by selecting this option.
