6.9 Logging online / offline

Before data can be archived, the storage media and one or more group channel data file enables must be
selected, the storage media inserted (if external) and logging set on-line.

When external archive media is inserted, a dialog is displayed giving the User the option of placing
the media on-line and starting the archiving process or remaining off-line. If no action is taken within
10 seconds, the media is placed on-line and archiving is started automatically.

Logging is set on-line (if archive media is present) or off-line by touching
operator menu for each Operator view.

Always set logging off-line before changing the storage media type selection (see Section 7.7.2,
page 70) or removing external media to prevent loss of data and possible damage to the media. A
warning is displayed if the storage media type selection is changed or external media is removed
before logging is set off-line
Note. Data stored in the internal memory buffer can still be transferred to the archive media when the
archive media is placed on-line again (providing it is not off-line so long that the un-archived data in the
internal memory is overwritten).

6.10 Backing-up archived data

It is advisable to back-up critical data stored on archive media on a regular basis. The recorder's internal
memory provides a buffer for the most recent data so, if data stored on archive media is lost, it can be
re-archived – see Reset archiving, page 53.
To ensure that all required data is available for re-archiving, it is recommended that data archived on archive
media is removed and backed-up before the recorder's internal buffer overwrites that data. The length of
time that data remains in the recorder's internal memory depends on the sample rate and the number of
channels selected – see Table C.1, page 170 for details.

6.11 Archive wrap

Archiving can be configured to delete the oldest archived data file automatically from the archive media
when the media approaches its maximum capacity – see Wrap, page 70.
