Appendix: ContactStore Version
9.2 Archiving
The hard disk has limited storage capabilities. When the available hard disk space is full, older recordings will be deleted,
overwritten by newer recordings.
· When you have configured a local archive drive, all your recordings will be archived. However, recordings made
before this was configured are not archived.
To keep copies of recordings or to protect the recordings in the event of failure/theft/destruction of the hard disk on the
recorder or to provide longer-term archive and replay capability, you can use a DVD+RW drive in or connected to the
ContactStore server.
With a DVD+RW drive installed or connected to the ContactStore server, you can archive calls automatically. The
application writes files to disk in batches as calls are recorded. It also archives the call details to the disks. Note that the
DVD+RW must be installed before ContactStore.
Recording files are copied to the DVD disk:
· When 14 hours of recordings have been made (equivalent to 100MB when recording in G.726 mode).
or
· When 24 hours have passed since the last write to DVD.
When a recording is archived, the index and the recording are stored. The index for the file is stored as an xml file on the
DVD. When a call is deleted from the hard disk, ContactStore prompts for the DVD that is specified as part of the archive
configuration.
The xml files associated with each recording are archived to the DVD along with the .wav files that contain the actual
recording. The xml files describe the recording and are useful for long term identification if necessary, for example if an
archived call needs to be retrieved after a number of years. If you need to retrieve an archived recording you can find
the index in the database and from it find out which DVD the recording is on.
· Tip
It is also advisable to keep backups of the call records from the database.
DVD+RW Media Control and Care
To find calls easily and reliably, be sure that all media are labeled, handled and stored correctly. To ensure maximum
reliability and consistent high quality recording and playback, follow these DVD+RW care procedures rigorously at all
times:
· Follow the manufacturer's guidelines for cleaning the drive's lens.
· Disks exposed to temperatures outside the operating environment must be stabilized before use. Leave the
cartridges in the operating environment temperature for a MINIMUM of two hours.
· Protect disks from extremes of heat. Do not store disks in direct sunlight.
· Avoid excessively damp environments; disks can be damaged by liquids and also by extreme humidity.
· Do not let disks get dirty. When not in use, store disks in their supplied protective container.
· Do not drop disks.
· Do not touch the optical media inside the cartridge.
