Recording Backup
Backup, also known as recording backup, is the process of
querying video stored on a hard disk of the NVR and then saving
to a USB storage device or a DVD-R disc as a file.
Recording backup has the following conditions:

Back up using a USB storage device: format the partition in
FAT32 or NTFS format; connect the storage device correctly
to the NVR.

Back up using a disc: use a GP65NB60 DVD burner. Make sure
the DVD-R disc is empty, and the burner is correctly
connected to the NVR.

Permission is required.

The recording to back up is stored on a hard disk of the NVR.
NOTE!

The default file format is .mp4 when you back up recordings
to a USB storage device.

When backing up using a disc, recordings are saved as .TS
files only.
