About archiving
Archiving is an integrated and automated feature with which recordings are moved to free up space for
new recordings. By default, recordings are stored in the database for each camera. The database for
each camera is capable of containing a maximum of 600,000 records or 40 GB. Milestone Husky
product automatically archives recordings if a camera's database becomes full. Consequently, having
sufficient archiving space is important.
You do not have to do anything to enable archiving. It runs in the background and is automatically
enabled and carried out from the moment your system is installed. The most recent recordings are
saved on a local storage in order to prevent network-related problems in the saving process.
The default settings for Milestone Husky product is to perform archiving once a day, or if your
database becomes full. You can change the settings for when and how often archiving takes place in
the Management Application. You can also schedule archiving (see "About archiving schedules" on
page 129) up to 24 times a day, with a minimum of one hour between each one. This way, you can
proactively archive recordings, so databases never become full. The more you expect to record, the
more often you should archive.
You can also change the retention time, which is the total amount of time you want to keep recordings
from a camera (recordings in the camera's database as well as any archived recordings) under the
properties of the individual camera.
Milestone Husky product automatically archives recordings if a camera's database becomes full. You
only specify one time limit (the retention time) as part of the general Recording and Archiving paths
(on page 70) properties. Note that retention time determines when archiving takes place. Retention
time is the total amount of time for which you want to keep recordings from a camera (that is
recordings in the camera's database as well as any archived recordings).
Backup of archives
Milestone does recommend that you create backups based on the content of camera databases as it
may cause sharing violations or other malfunctions. Instead, create backups based on the content of
archives. If you have not specified separate archiving locations for separate cameras, you could back
up the default local archiving directory, Archives.
Important: When you schedule a backup, make sure the backup job does not overlap with any
scheduled archiving times.
If archiving fails
Under rare circumstances, archiving may fail, for example due to network problems. However, in
Milestone Husky product this does not pose a threat. Milestone Husky product creates a new
database and continues archiving in this new database. You can work with and view both this new
database and the old one like any other databases.
About archiving locations
The default archiving folder (see "Default File Paths" on page 37) (C:\MediaDatabase) is located on
the Milestone Husky product server. You can change the default archiving folder to any other location
locally, or select a location on a network drive to use as the default archiving folder. In the archiving
folder, separate subfolders for storing archives for each camera are automatically created. These
