Snapshot
A snapshot is initialized with a data duplicate from a source to a target. The mirror snapshot
is offered by the
Accustor
RAID controller.
Note
The source and target volume of the snapshot must be identical.
Before setting a snapshot, you need to set the slice in the array. The capacity of each slice and
the number of shots should be in accordance with the space you need.
In the figure above, a snapshot can be created by splitting the source and target after the
background sync is completed. The I/O mirroring is stopped, and the difference is under
tracking in a bitmap table to support fast re-sync.
Create Shot
Create a snapshot of the selected slice. A maximum of 8 shots can be created. Once all shots
have been used, older shots must be deleted before new ones can be taken.
1. Select the
Create Shot
function from the drop down menu.
2. Select the required shot by clicking on the Shot No. radio button. From the respective drop
down menus, select the source volume and destination volume. Unavailable shots are
grayed out.
3. Check the
Confirm
box and click
OK
to take a snapshot.
