IMPORTANT. 10-30 GB of free space is always preserved on Storage. For NAS storages this amount vary between
50 and 100 Gb (depending on the storage size). If only one system partition (where OS is installed) is present, then DW
Spectrum will use this partition for recording. If any other disk is added and an extended partition is created, then the
system partition will be disabled for recording and DW Spectrum will record data to the extended partition(s).
Configuring Redundant Storage (Storage Backup)
DW Spectrum provides the ability to make the storage redundant. That means, even if the server the recording is
performed on, goes offline, the archive will still be available. This is especially useful in multi-server environments.
The following scenarios are most commonly used:
 Servers record and back up the archive to a NAS device.
 Servers back up to each other.
The following options are available:
 Backing up footage from specific Cameras
 Backing up specific streams (Hi-res or Low-res) if necessary
 Different backup modes.
To set up storage as a backup one click Use as backup storage. If at lease one storage is set for backup, the additional
settings will be available. To return storage in a regular mode click Use as main storage.
IMPORTANT. It is necessary to have at least one active main storage.

2. Add NAS to Server (see "Configuring Server Storage/NAS").
3. Click Use as backup storage.
4. Setup backup parameters (described below).
5. Repeat the above steps on remaining servers.
