2/ NetVault Administrator’s Guide recommends windows network timeout is configured see below:
Configure network time-outs — Backup and restore jobs often take a long time to complete. Although the DD Boost Library can recover from temporary network interruptions, the operating system on the data protection application system might terminate a job prematurely if the data protection applicationtime-outs are set too low. To avoid this, Data Domain recommends setting time-outs to at least 30 minutes (1800 seconds).
