Backup for Archiving (Long-Term Storage of Data)
When making a backup of data for long-term archive, you must back up the following data:
Recorded video data ---- It is recommended to make an incremental backup of this data.
Refer to P. 217 for the file names and storage location.
Event data ----------------- It is recommended to make an incremental backup of this data.
Refer to P. 218 for the file names and storage location.
Configuration file --------- Usually, make a backup of the configuration file when the
system is installed, and do it again each time you change the
settings of the VK-64/VK-16. However, if doing so makes
management complicated, you can perform a full backup every
day. Refer to P. 218 for the storage location.

Notes on Backing Up Recorded Video Data
Video data being recorded is saved in a temporary file, and the file is settled and saved as
video data when its size reaches 1 GB (by default) to the storage drive. The temporary file
cannot be backed up in the normal procedure. Therefore, backup only the settled files.
Refer to “Backup for Data Protection” (➝ P. 219) for details.
When choosing the backup device, consider the backup unit. For example, if the backup
unit is 100 through 400 GB, use a high-density tape device called “LTO device”. If it is
around 2TB (far beyond 400 GB), consider LTO auto loader device.
