Backup for Data Protection
About Backup
When making a backup of data for protection, 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. The temporary file cannot be
backed up in the normal procedure. Refer to “Recorded Video Data” (
➝ P. 217) for
details.
The temporary file cannot be backed up until it is converted into video data.
You should choose the backup hardware best suited for the backup data quantity.
Basically, you should use the DDS type device if a single backup copies 1 through 10 GB
of data, and AIT device if it copies 10 GB through 100 GB of data, and LTO device if it
copies 100 through 400 GB of data. If you need more capacity, you need to consider
multiple backup devices. Also, it is recommended to use a backup device with a high data
transfer rate.
If the total capacity of the hard disk reaches several terabytes, you should rather consider,
than making backups, using hot-spare hard disks or highly reliable storage system, or
further reliable and available RAID system.
