subfolders are named after the MAC address of the hardware device to which the camera is
connected.
Because you can keep archives spanning many days of recordings and archiving may take place
several times per day, further subfolders, named with the archiving date and time, are also
automatically created.
The subfolders are named according to the following structure:
...\Archives\CameraMACAddress_VideoEncoderChannel\DateAndTime
If the video encoder does not have several channels, the video encoder channel will always be _1
(example: 00408c51e181_1).
Example: an archiving at 23.15 on 31st December 2012 for a camera with the MAC address
00408c51e181 attached to channel 2 would be stored:
C:\MediaDatabase\Archives\00408c51e181_2\2012-12-31-23-15
About archiving to other locations
When you archive to other locations than the default archiving directory, your system first temporarily
stores the archive in the local default archiving directory, then immediately moves the archive to the
archiving location you have specified. Archiving directly to a network drive can mean that archiving
time varies depending on the available bandwidth on the network. First storing the archive locally, then
moving it speeds up the archiving procedure, and reduces delays in case of network problems.
If you archive to a network drive, the regular camera database can only be stored on a local drive
attached directly to your system's server.
About dynamic archive paths
With dynamic archiving paths, you specify a number of different archiving paths, usually across
several drives. Milestone recommends using dynamic paths, which also is the default setting when
you configure cameras through the Configure video & recording wizard (see "About video and
recording configuration" on page 64).
If the path containing the camera's database is on one of the drives you have selected for dynamic
archiving, your system always tries to archive to that drive first. If not, your system automatically
archives to the archiving drive with the most available space at any time, provided a camera database
is not using that drive.
The drive that has the most available space may change during the archiving process, and archiving
may happen to several archiving drives during the same process. This does not have impact on how
users find and view archived recordings.
Dynamic archiving paths are general for all your cameras. You cannot configure dynamic archiving
paths for individual cameras.
When deciding which drives to use for dynamic archiving, consider the pros and cons in the following
examples (in which we assume that the default archiving path (see "Default File Paths" on page 37) is
on drive C:
—drive letters are examples only, different drive letters may of course be used in your
organization):

Camera records to drive C: and archives to drive C:
If the path containing the camera's database is on one of the drives you have selected for
dynamic archiving, Milestone Husky product will always try to archive to that drive first.
Archiving will take place quickly, but may also fill up the drive with data fairly quickly.
