Snapshot Options:

Snapshot Numbers: Specifies the total number of snapshots that will be created.

Snap Ratio (%): This is the ratio in percentage between the snapshot volume
and the volume of origin. This indicates the ratio of the volume size that will be
set as the size of the snapshot volume. For example, if your logical volume is 1GB
and the Snap Ratio is 10%, the size of the snapshot volume that will be created is
512MB, assuming that your PE size (VG Unit Size) is 512MB. The snapshot
volume size will always be a multiple of PE size and the smallest snapshot size is
equal to the PE size.

Overwrite: Selecting this option will automatically delete the oldest snapshot if
the total number of snapshots is already exceeded.

Mount: When checked, it means that the created scheduled snapshot will be
automatically mounted.

Reserved/VG Free Size (MB): The left side indicates the total volume space
that will be used for the creation the snapshots. The right side indicates the free
space of the volume group available for use.

Execute Day: Specifies whether the scheduled task is to run on the selected
day(s).

Execute time:
Once - Specifies the time of the day when the scheduled task will be taken.
Every - Specifies how often the scheduled task is to be repeated. You can
also select the starting time and the ending time.

Snapshot Lists:
Mount - Allows you to mount the snapshot volume. All snapshot volumes will
be mounted read-only. By mounting the snapshot volume, the files under this
snapshot volume will become accessible.
Name - This specifies the name of the snapshot volume. If the snapshots are
created by schedule, proNAS will automatically create the snapshot name. The
format that will be used is: the last two digit of the year, followed by the
month/date, and then followed by the hour/min/sec. For example:
"101217_151612".
Date - This indicates the date and time when the snapshot was created.
Used Size - This indicates the space used by the snapshot data. The right
side is the size of the snapshot volume. If the used space nearly exceeds the
snapshot volume capacity, it will be set as "Invalid" and will be un-mounted
automatically to keep the system consistent.
3. A confirm message window will be displayed. Select “Yes” to proceed.
4. An “Updating Volume Setting” message will be shown.
