To maintain a copy of the video recorded in your system, you can archive the video into Avigilon Backup (AVK) format. AVK files can be opened in the Avigilon Control Center Player and reexported as needed. Video archiving can be configured to occur continuously or on demand.
You can enable the Continuous Archive feature to automatically archive video to the archive directory in hourly blocks during the configured time frame.
We recommend that you set up the Continuous Archive feature to work with video data aging. Data aging increases the amount of video that can be stored by discarding high-resolution video when the Tier 1 storage is full and keeping only low-resolution video. The oldest video stored will be low-resolution. By configuring the two features together, you can create a tiered storage configuration to help manage the amount of video retained on the local ACC Server.
We performed tests with the continuous archive feature to archive video to Dell EMC Isilon clusters. Dell EMC PowerEdge servers with high-performance drives or Dell EMC SAN storage can be used for storing local video with Dell EMC Isilon storage for archiving. Together, you can create a tiered storage configuration.
The following table provides bandwidth-sizing guidelines based on our test results.
