NVBMR Online backup for Linux fails with "Timeout expired while waiting for Xfer data" (80224)

NVBMR Online backup on some Linux client fail with the following log errors:
--------------------
The backup information file is incomplete.
Error writing backup output. The backup is incomplete!
Timeout expired while waiting for Xfer data, Consider increasing timeout value
Fatal Error, while xfer data from BB agent
Failed to handle incomming msg from BB agent
Failed to enter msg loop
Failed to backup system images
----------------------

Before backing up linux client NVMBR online uses Storix to create a 'backup list' which will contain the objects that will be part of the image.
By default there is a 360 seconds timeout for this backup list to complete.
On some systems where there are millions of small files, the timeout is not enough and the backup list creation fails.

- open nvconfigurator on the Linux client to backup
- go to 'Plugin Options' tab > 'VaultDR online Linux' tab
- on the 'BB Agent Timeout' field, change the value from the default '360' to '3600' seconds
It would take approximately 22 minutes to build a list for 15 million files, therefore considerably increasing the timeout value will help
if the file system contains a larger number of sparse files for instance.
