Abstract:
1. A method for backing up data, comprising: providing a probe, the probe detecting changes in a host; receiving information about a load of a backup server; determining a probe frequency, wherein the probe frequency defines how often the probe should be polled, wherein determining the probe frequency includes adjusting the probe frequency based on the load of the backup server; waking the probe at the probe frequency; polling the probe to obtain information about the host for a time interval, wherein the probe sleeps for the probe frequency after the time interval; adjusting the probe frequency based on information obtained by polling the at least one probe wherein adjusting the probe frequency includes reducing the probe frequency based on a negative result from polling the at least one probe and applying a scaling factor to reduce the probe frequency to reduce utilization of the backup system; and backing up data based on the information.
