Backup Scheme
Backup Procedure for Video Data and Event Data
Back Up Video Data and Event Data.
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.
Refer to “Server Sizing Concept” (➝ P. 29) for details.
Prepare the backup device and backup tool for Windows according to the estimated
quantity.
Set up the backup tool as directed on P. 219 and P. 220.
Be sure to exclude the temporary files from the backup target.

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:
Lower the recording frame rate during backup in the
Recording Schedule Setting window.
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.
Use multiple Storage Servers and use a dedicated backup
device for each server. Refer to P. 28 for how to use multiple
Storage Servers.
