Chapter 8 - Managing Network Attached Storage
Volume Snapshots
For example, if you write 100 GB to the volume, and then make a snapshot of that data, the
snapshot is only a few kilobytes in size, as it simply points to the existing data. However, if
that 100 GB is deleted, the snapshot grows to 100 GB, because it must retain the data. When
the snapshot containing the 100 GB of data is deleted, either manually or based on schedule
retention, then 100 GB of capacity is made available for new data.
Create a Snapshot
Use the following steps to create a snapshot.
1.
From the menu bar, select
Configuration > NAS > Volumes

then select
