Recovery Status
|
Amount of Data to be Recovered
|
With the
Current filter selected, this is the logical size of the data yet to be recovered.
- When a historical period is selected as the filter, the meaning of
Total Amount Data to be Recovered is the average amount of data pending recovery during the selected time.
- For example, if the first hourly snapshot of the data showed 400 GB of data to be recovered in a historical time period and every other snapshot showed 0 GB waiting to be recovered, the value of this field would be 400 GB divided by the total number of hourly snapshots in the period.
