Tip: To maximize load sharing and optimize performance, distribute archives across your available
storage space, if possible.
Note: If specifying another archiving location than the default location , the location you specify must
exist. You are not able to create new directories as part of the process. If archiving to a network drive,
the regular camera database must still be stored on a local drive, i.e. a drive attached directly to the
computer running the NetDVMS system.
Archives for the selected camera will be stored in separate subdirectories under the Archives directory
at the location you specify. The subdirectories will be named according to the following structure:
...\Archives\CameraMACAddress_VideoEncoderChannel\DateAndTime
Example: With the default archiving folder located under C:\videodata, recordings from an archiving
taking place at 23.15 on 1st June 2008 for a camera attached to channel 2 on a video encoder device
with the MAC address 00408c51e181 would be stored at the following destination:
C:\videodata\Archives\00408c51e181_2\2008-06-01-23-15
If the device to which the camera is attached is not a video encoder device with several channels, the
video encoder channel indication in the subdirectory named after the device's MAC address will always
be _1. Example: 00408c51e181_1.
Dynamic Archiving
Dynamic archiving is ideal if you wish to archive to several drives during the same archiving process
but do not want to worry about how much space is used on each drive. Dynamic archiving is only
possible when you select the Automatic path selection check box.
When you select Automatic path selection, you will be able to specify archiving locations for all
selected cameras in one go. In the Select drives for dynamic archives section, simply select the box
next to each drive required as archives.
Note that it is only possible to select drives; you cannot edit the paths. An Archives directory will
automatically be created in each drive, and the archiving will take place the same way as described
previously under Specifying that Archiving Should Apply for Specific Cameras.
If you need to use a path for archiving that is not in the list, click the Add target button which is
described previously.
What Happens During Dynamic Archiving?
If the drive on which the camera stores its regular database is among the drives you have selected for
dynamic archiving, archiving for the camera in question will always take place to that drive first.
If the drive on which the camera stores its regular database is or becomes full—or if it is simply not
among the drives selected for dynamic archiving—archiving will take place to the selected drive with
the most free disk space. Which drive that is may change during the archiving process, and archiving
