Same Drive: Automatic Moving or Deletion of Archives if Running Out of Disk Space
In case the NetDVMS server is running out of disk space, and the archiving drive is
identical to
the camera
database drive, NetDVMS will automatically do the following in an attempt to free up disk space:
•
Backing Up Archives
Many organizations want to back up recordings from cameras, using tape drives or similar.
Creating such backups based on the content of camera databases is not recommended; it may
cause sharing violations or other malfunctions.
Instead, create such backups based on the content of archives. If you have not specified separate
archiving locations for separate cameras, you could simply back up the default local archiving
directory,
Archives
.
When scheduling a backup, make sure the backup job does not overlap with your specified
archiving times.
•
Viewing Archived Recordings
You view archived recordings in the
Viewer
or
NetGuard-EVS
. This way, you are able to use all of
Viewer's or NetGuard-EVS's advanced features (video browsing, smart search, evidence export,
etc.) for archived recordings as well.
Archives Stored Locally or on Network Drives
For archived recordings stored locally or on network drives you simply use the Viewer's or
NetGuard-EVS's browsing features, for example the timeline browser or the playback controls, for
finding and viewing the required recordings; just like you would with recordings stored in a camera's
regular database.
Exported Archives
For exported archives, e.g. archives stored on a CD, you must use the Viewer: Click the browse
button in the Viewer's
Database Information
control panel to browse for the archive you want to
view. Once you have specified the required archive this way, you can use all of the Viewer's
browsing features for navigating the recordings in the archive.

Virus Scanning and Archiving
If allowed in your organization, disable any virus scanning of camera databases and archiving
locations. For more information see
Virus Scanning Information

New Database if Archiving Fails
Under extremely rare circumstances archiving may fail. For example, a database may be full and
ready for archiving, but the operating system may lock content in the database if a content file is
open. This would prevent archiving. In practice, this situation would only occur if somebody
attempted to view a database file (e.g. a .pic file) directly from the database folder at the time of the
archiving (viewing the file directly would not work since database content cannot be viewed as
individual files, only through a NetGuard-EVS or Viewer).
