Examples
Configuration 3: Backup for Data Archiving
Premise
5 units of VB-C50i
Recording condition
Frame rate is 1 fps (one frame per second), Camera Server video quality is 50, resolution is 320x240, and the
size for one image data is 15 KB.
The [Maximum file size / duration] option in the [Storage Server Configuration] window is set to six hours.
Under this condition, the video file size per Camera Server per day is 310 MB x 4 files.
Therefore, the video data quantity per Camera Server per day is 1.25 GB and 6.25 GB for five Camera Servers.
Hardware requirement
6.25 GB per day x 30 days = 190 GB Hard disk capacity of around 240 GB is required.
If the storage period of video data on the Storage Server is 30 days, and the required archive period is 180
days, an archive backup for 1-week data can be saved on 50-GB tape with an AIT drive. If you use a 100-GB
LTO drive, you can save 1-week backup data.
However, if the tape capacity for archive is too large, we should consider that it takes too long to find desired
data from the restored data.
Configuration 4: Backup from Multiple Storage Servers (Backup for
Data Protection)
Premise
100 units of VB-C50i
Recording condition
Frame rate is 1 fps (one frame per second), Camera Server video quality is 50, resolution is 320x240, and the
size for one image data is 15 KB.
Twenty Camera Servers are registered in five Storage Servers to record video.
The [Maximum file size / duration] option in the [Storage Server Configuration] window is set to six hours.
Under this condition, the video file size per Camera Server per day is 310 MB x 4 files.
Therefore, the video data quantity per Camera Server per day is 1.25 GB and 25 GB for twenty Camera
Servers.
Hardware requirement
25 GB per day x 30 days = 750 GB Ten servers is required (for each Hard disk capacity of 900 GB or
more).
In this case, it is ideal to prepare one backup device for each server for backup. If you use a 400-GB LTO
drive, you can save 2-week data on a single cassette of tape. Alternatively, you can prepare two or three
servers dedicated for backup, and use network backup for central management.
