Replication of archives refers to constant, block-by-block copying of fixed-size information (video, audio, metadata) from one archive to another archive within the same domain. The primary purpose of data replication is to ensure long-term storage and access to multimedia recordings on remote storage devices.
Attention!
Any archive can be the source or recipient of replication. Moreover, every archive can simultaneously be both the sender and recipient of data.
Attention!
Replication occurs as information blocks are accumulated. 1 block may contain more than a minute of video.
Attention!
Replication is performed only to the end of the archive. It is not possible to overwrite existing data in the archive.
To transfer the old data from Archive 1 to Archive 2 and continue writing new data to Archive 2, do as follows:
- Replicate the data from Archive 1 to Archive 2, while Archive 2 cannot be written to.
- Configure the camera to write to Archive 2.
Note
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 Configuring Macros and Counters).
To configure data replication:
- In the list of archives on the 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 camera storage (4, see The Embedded storage object).
For each archive, select the cameras from which data will be copied to the source archive (2). To select all cameras, click the Select All button.
Note
Data for 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.
Note
You cannot select cameras if they are already recording to the replication archive.
Select the replication process period (3):
Always – 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.
On demand – replication will be started manually or using macros (see Manual Archive Replication, Start replication).
- Click the Apply button.
Data replication configuration is complete. If the replication period was set to Always, data replication starts immediately after the settings are applied.
