Logical capacity is the amount of data the backup application wrote, while the physical capacity is the amount of data actually stored on the disk. Select the Show Details link in the first section to display the breakdown of the logical and physical capacity and the deduplication ratio. To export the deduplication CSV data, enter the number of days to include in the report and select Export. (See "Exporting CSV Data" on page 187 for more information.) To change the information displayed in the graphs: 1. Select the date range to include in the report: • Start date - the date you want as the starting point for stepping back into the past by some number of days to establish a particular date range. This is effectively the end date of the date range. • Hour of the day - the hour of the day, in 24 hour time, to use in conjunction with the Start date. • Going back - the number of days to step back from the selected start date to establish a date range. For example, if you select June 20 at 10 going back 3 days, the graph will include data from June 17 at 10:00 a.m. to June 20th at 10:00 a.m. NOTE: The greater the number of days included in the date range, the fewer the data points for each day will display in the graphs. For example, for two days of data the graphs will show one data point for every two hours, while for seven days of data the graphs will show one data point for every seven hours. 190 Monitoring
