QNAP QTS 4.5 Series User Manual

Setting Description
When the number of
snapshots reaches maximum
Specify the default QTS behavior after a volume, LUN, or NAS reaches its
maximum number of snapshots. You can choose one of the following
behaviors:
• Overwrite the oldest snapshot when taking a new one.
• Stop taking snapshots.
Use timezone GMT+0 for all
new snapshots
Enable this feature to use the GMT+0 time zone in the file names of new
snapshots. This file naming convention can simplify snapshot management
especially when working with snapshots from NAS devices located in
different time zones.
This setting only applies to new snapshots. Existing snapshots are not
renamed.
Show hidden files in
Snapshot Manager
Enable this feature to display hidden files in Snapshot Manager. This setting
does not affect files inside the File Station Snapshot Directory.
Enable Windows Previous
Versions
When enabled, Windows users can view and restore files from snapshots
using the Previous Versions feature in Windows. You can disable this
feature for individual folders by modifying the folder's properties.
Storage
QTS provides a flexible storage architecture that enables you to easily manage, store, and share files.
Disks
Disk Types
QTS restricts which type of disk can be used to create SSD cache, storage pools, and static volumes.
Important
• For compatibility reasons, PCIe form-factor SSDs and PCIe M.2 SSDs installed in
third-party adapter cards cannot be used to create storage pools and static volumes.
• If you are already using NVMe PCIe SSDs for data storage, then your existing storage
configuration will not be affected after upgrading to the latest version of QTS.
