Configuring Your ReadyNAS
v1.0, October 2007
You can also specify how long a snapshot should last. If you will be using snapshots for
backups, you can schedule the snapshot to last slightly longer than the expected duration of the
backup. Having an active snapshot can affect the write performance to the ReadyNAS, so
deactivating it when it is not needed might be advantageous in write-intensive environments.
When a snapshot is taken, snapshots of shares appear in your browse list alongside the original
shares, except the snapshot share names have
-snap
appended to the original share names. For
example, a snapshot taken of a share backup is available as
backup-snap
.
You can traverse a snapshot share just as you would a normal share except that the snapshot share
is read-only. If you wish, you can select a detailed listing to show the snapshot time in the
Description
field.
Snapshots can expire when the reserved snapshot space is filled. The snapshot mechanism keeps
track of data that has been changed from the original volume starting at the point when the
snapshot is taken. All these changes are kept in the reserved snapshot space on the volume. The
Disk space
utilization field on the Volume screen shows how much space has been reserved for
snapshots.
