Backup Procedure for Video Data and Event Data
Back Up Recorded Video Data and Event Data.
1. Estimate the total quantity of recorded video data for backup.
The video data quantity per day can be calculated as: Image file size per frame x Frame rate x Number of
Camera Servers x Recording time (seconds) per day.
See "Server Sizing Concept" (  P. 1-20) for details.
2. Prepare the backup device and backup tool for Windows according to the estimated quantity.
3. Set up the backup tool as directed on P. 7-4.
Be sure to exclude the temporary files from the backup target.
Note
If the VK-64/VK-16 continues recording video while making a backup, you must take into account the
increased I/O load on the hard disk due to data transfer to the backup device. If the recording frame rate of
the Storage Server is reduced by performing the backup, consider the following:
z Lower the recording frame rate during backup in the Recording Schedule Setting window.
z Establish multiple I/O channels (e.g., RAID cards) on the Storage Servers to deploy multi-storage
configuration and distribute the recorded video data among servers. Choose a backup device according
to the storage configuration.
z Use multiple Storage Servers and use a dedicated backup device for each server. See P. 1-19 for how to
use multiple Storage Servers.
