Overview
The appliance can take snapshots of volumes. A volume snapshot is a read-only copy of a
volume as it was at a particular point in time.
The appliance automatically takes snapshots before performing a cloud backup or running an
outgoing synchronization rule for a NEXT3 volume, so as to ensure that a consistent image of
all files is transmitted. In addition, you can schedule automatic daily snapshots and take
snapshots manually.
You can use snapshots to access previous versions of your volumes and the files contained
therein.
Terminology
The appliance supports two types of snapshots:
Cloud Snapshots
Cloud snapshots are snapshots that are stored online using CTERA’s Cloud Backup service.
They are automatically generated with each cloud backup operation.
