Item Description
Logbias Change the logbias setting by making a selection from the Logbias drop-down list:
• Latency. Data requests are handled at high priority with a minimum of delay, but data
throughput might not be optimum. This is the default setting that is automatically
assigned when you create a share.
• Throughput. Data requests are handled with high data throughput, but there might be
delay in response to requests.
Compression Select the Compression check box to enable data compression. Compression saves
storage space and increases the speed of data transfers, but the compression and
decompression processes require additional resources.
Dedupe Select the Dedupe check box to enable deduplication, which prevents storage of redundant
data on the share. Unique data is stored only once on the share, and other instances of the
identical data are removed and replaced by a pointer to the unique data. This storage
method saves storage space and increases the speed of data transfers. By default, the
Dedupe check box is cleared.
Note: You can enable deduplication for a thin LUN but not for a thick LUN.
Note: NETGEAR does not recommend enabling deduplication for performance-sensitive
data on applications such as virtual machines and databases.
Provision The provision setting is provided for information only. You cannot change the provision
setting of an existing LUN.
Size For information about how to expand the size of an existing LUN, see
LUN on page 98.
Protection
Continuous Select the Continuous Protection check box to enable data protection through snapshots
Protection and configure the frequency at which snapshots are made. By default, the Continuous
check box is selected. For more information about snapshots, see

Select the Smart Snapshot Management check box to enable automatic
snapshot pruning. When enabled, this feature deletes older hourly and daily
snapshots so that hourly snapshots are kept for 48 hours, weekly snapshots
are kept for 8 weeks, and monthly snapshots are kept indefinitely.
Note: For shares or LUNs that were created before the release of this
feature, Smart Snapshot Management is disabled by default.
The interval specifies how often a snapshot is made. Make a selection from
the drop-down list:
• Hourly. A snapshot is taken every hour on the hour.
• Daily. A snapshot is taken every day at midnight. This is the default
setting.
• Weekly. A snapshot is taken every week on Friday at midnight.
