Linksys Small Business NSS4000 and NSS6000 Series Network Storage System Administration Guide
As part of your backup strategy, you can configure the NSS6000 to capture
snapshots of the data stored on a volume. You can define a snapshot to occur at
various frequencies (such as hourly, daily, weekly, and so on). Individual snapshots
are overwritten by the subsequent snapshot for the same interval. For example, if
you set up an hourly snapshot, the 10:00 a.m. snapshot is replaced by the 11:00
a.m. snapshot (and so on).
You can also configure multiple snapshots for the same volume. For example, you
might set up an hourly snapshot, another snapshot to occur every four hours, and a
daily snapshot. Each of these three snapshots is maintained separately and is only
overwritten by the subsequent snapshot of its own frequency type. The
snapshot(s) reside in the reserve area allocated for each snapshot. When you
create a snapshot, the end user can access it by logging into the NSS with their
username and password. Each snapshot appears as a copy of the share
accessible by the end user.
The snapshot reserve is the amount of space that you want to allocate on the array
to the snapshot. Once set, this space is not available for other storage use. The
recommended amount of a reserve is generally between 10 to 20% of the total
volume size. If the period of time between snapshots is greater, the amount of the
reserve should be greater. Or, if there is a heavy amount of activity on the volume,
set a higher reserve.
This feature is only available on NSS6000 series NAS units.
To create a snapshot for a volume:
