does rman backup on a network drive would save disk usage?

Hi experts,

I have an oracle 11g server in a virtual machine (128 GB ram, 4 partitions, same disk in the vm server) generating around 60GB of archive log every 2 hours and an incremental backup every 24 hours taking around 6 hours to complete.

In the last incremental backup, the server hang-up due to extensive disk usage and we are planning to direct the backup to a network file system to avoid the disk usage problem since the disk IO would be done by the network hardware instead of the disk controller serving the user connections.

Does this solution (workaround) really save the disk usage in the server?

    Please define 'extensive disk usage'. Running out of space? I/O contention? In either event, what diagnostics lead you to your conclusion? Did you get any error messages resulting from "the server hang-up"?

    The direct interface between the VM and the network disk may be a network interface, but there is still a disk controller behind that.

    instead of the disk controller serving the user connections.

    What disk activity is a direct result of" disk controller serving the user connections." What are these "user connections" doing.

    Also note that 11g has been out of support since Dec 2020.
