Problem description
Phoenix uses three types of the VMware Transport Modes.
HotAdd
NBD-SSL
NBD
The HotAdd mode is the fastest among the other two transport modes.
By default, Phoenix uses 'HotAdd' as the transport mode.
How to view the type of Transport Mode used in logs?
On the Jobs page, click the VMware tab > Job ID.
On the Job Details page, click the Progress Logs tab.
The Progress Logs tab displays the transport mode used as shown in the following screenshot:
Resolution
Backup may fail with 'Backup Window expired' if the transport mode is changed from HotAdd to NBD or NBD-SSL as the other two modes will take time to backup as compared to HotAdd.
The Transport mode will be changed by VMware depending on the various scenarios.
