Solution

1.       Go to Media Server

2.       Check bp.conf file and make sure that “BPSTART_TIMEOUT=” key has correct value.

NOTE: The default timeout is 300 seconds (5 minutes)

3.       If the value of “BPSTART_TIMEOUT=” is incorrect, correct it or if not needed, remove it from bp.conf file.

4.       Re-run the backup and check if issue persist.
