Replication of the archive data refers to the copying of fixed-size blocks of information (video, audio, metadata) from one archive to another within the same Axxon-domain. The primary purpose of data replication is to ensure long-term storage and access to multimedia data on remote storage devices. Every archive can be both the sender and receiver of data.

- Replication In a block archive, replication is performed as blocks of information accumulate and only to the end of the an archive. Blocks In an object archive, blocks of information can be replicated to any part of the archive in the object an archive. To transfer the old data from Archive 1 to Archive 2 and continue recording new data to Archive 2, do the following:
from - from Archive 1 to Archive 2, recording isn't performed to Archive 2.
- Configure the camera recording
- to Archive 2.
The events indicating the start and successful completion of data replication are generated in the system (see Event control). These events can be used in macros (see Programming).
- Archives can use block or object type of storage (see see General information about server archives). To successfully replicate data from an object archive to a block archive, you must create the NGP_ARCHIVE_REPLICATE_FRAME_BY_FRAME environment variable with the value true or 1 (see Appendix 9. Creating system variable).
