Replication of archives the archive data refers to constant, block-by-block copying of fixed-size blocks of information (video, audio, metadata) from one archive to another archive on 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 is performed as blocks of information accumulate and only to the end of the archive. It is not possible to overwrite existing data in the Blocks of information can be replicated to any part of the archive in the object archive. To transfer the old data from Archive 1 to Archive 2 and continue writing new data to Archive 2, do as followsthe following:

The primary purpose of data replication is to ensure long-term storage and access to multimedia recordings on remote storage devices. |
Any archive can be the source or recipient of replication. Moreover, every archive can simultaneously be both the sender and recipient of data.
Events The events indicating the start and successful completion of data replication are will be generated in the system (see Event Control). These events can be used as macro triggersin macros (see Configuring Macros and Counters). |
To configure data replication, do the following:
- In the list of archives on of the Axxon-domain, select the archive to which you want to copy data from other archives.
Select one or more archives form which you want to copy data (1). You can also replicate video from on-board the embedded camera storage (4, see The Embedded Storage storage object).
For each archive, select the cameras from which data will be copied to the source replication archive (2). To select all cameras, click the Select Allall button.
Info title Note Data for from a particular camera can be copied to the replication archive only from one archive. When you select a camera for replication from an archive, the camera becomes unavailable for replication from any other archive.
Info title NoteYou cannot select cameras if they are already recording writing to the replication archive.
Select the replication period (3):
Always - replication is — replication will be performed continuously.
- Time zone — replication will be performed within the specified time schedule (see Creating schedules). For example, to distribute the CPU load, you can configure replication to run at night.
- You can use macros to replicate on schedule (see
On demand - replication is performed manually.
Note title Attention! — replication will be started manually or using macros (see Manual Archive Replication, Start replication).
- Click the Apply button.
