6.7 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 50.
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 162 for details.

6.8 Archive Wrap

Archiving can be configured to delete the oldest archived data file automatically from the external media
when the media approaches its maximum capacity – see 'Wrap', page 91.
