A method, article of manufacture, and apparatus for efficiently backing up information are disclosed. In some embodiments, this may comprise determining a probe frequency, polling, at the probe frequency, at least one probe to obtain information about a computer system, and backing up data based on the information. In some embodiments, determining the probe frequency includes receiving a user-defined interval.

Probe based backup

A method for restarting backup including receiving an indication of an interruption to a backup process, saving data backed up prior to the interruption as a partial save set, and upon restart of the backup process, saving subsequently backed data in one or more subsequent partial save sets linked to a first partial save set.

Checkpoint restart

A method, article of manufacture, and apparatus for efficiently backing up information are disclosed. In an embodiment, this may comprise receiving information about a computer system from at least one probe, selecting data to be backed up, and backing up the selected data. Boolean and/or conditional logic may be applied to the information received from the probes, and data backed up based on the logic analysis. A probe frequency may be determined and used for polling probes, and the probe frequency may be adjusted based on factors such as the received information, server utilization, and network utilization. A modular approach may be used in which a probe determines whether a condition has been met, and transmits that determination to a backup server.
