This is mainly for my own reference but if it turns up in a Google search and helps somebody that’d be cool too. I’ve just set up a full machine backup using the tools built into Windows 7. The following command when executed as an administrator will backup the entire contents of C: and D: drives to an E: drive at 3am daily:
SCHTASKS /Create /SC DAILY /TN DailyBackup /RL HIGHEST /ST 03:00 /TR "WBADMIN START BACKUP -backupTarget:e: -include:c:,d: -allCritical -quiet >> E:\backupLogs.txt"
In my experience the backups run a *lot* faster than when using the GUI front end.
