Creating a Snapshot for a Volume
Network Storage System (NSS) Administrator Guide
Chapter
4
The
Storage Snapshots
page appears.
2. From the
New Snapshot
table, click the volume for which you are creating the snapshot.
3. Depending on the frequency, use the first part of the
Every
field to enter a unit of time. Tab to the
second part of the
Every
field, and then click the snapshot frequency (that is, hours or days). For
example, set the first part of the field to "7", and the second part to "Days" to take a snapshot
once every week.
4. Use the
At:
fields to set up the timing for the snapshot. For example, if the frequency is set to
Days, set the hour and minute of the day at which you want the snapshot to be taken.
Note:
When entering the hour, use the 24-hour clock. For example, 3 p.m. should be entered as
15:00. When the frequency is set to Hours, you can only edit the minutes part of the
At:
field.
5. In the
Reserve Size
field, enter the amount of space (in MB) that you want to allocate to the
snapshot. This space becomes unavailable for any other storage on the array. Note that you
must enter a minimum of 32 MB in this field.
NOTE:
The snapshot is built at the array level. The
Volume
column currently shows the
amount of space left on the array on which the volume is located. To calculate the
reserve size, refer to the applicable volume size as listed on the
Volume
page.
6. Click
Add
to save the snapshot.
The snapshot details appear in the
Currently Active Snapshots
area at the top of the page.
