These applications have a lot of data those are important for enterprise. Generally this data is very big in size. So backing up them become a time and network bandwidth consuming process. Some times backup application can take the whole bandwidth and other services fails. The bottleneck in this situation is generally bandwidth or bursts in this network usage.
