Abstract
First deficiency information according to a deficiency period of time-series data in a first recording unit among plural recording units and second deficiency information according to a deficiency period of time-series data in a second recording unit are obtained. Then, it is controlled to combine electronic data of a non-deficient period in the first recording unit and electronic data of a non-deficient period in the second recording unit with each other and record the combined electronic data, based on the obtained first deficiency information and the obtained second deficiency information.
Claims25
A recording control apparatus which controls recording of data transmitted from a network camera to plural recording units, the recording control apparatus comprising:
- a designating unit configured to designate a period of the data transmitted from the network camera to the plural recording units to be recorded in a backup storage unit as backup data;
- a first obtaining unit configured to obtain first deficiency information according to a deficiency period of the data transmitted from the network camera and recorded in a first recording unit for the designated period;
- a second obtaining unit configured to obtain second deficiency information according to a deficiency period of the data transmitted from the network camera and recorded in a second recording unit for the designated period;
- a selection unit configured to select one of the first recording unit and the second recording unit based on the obtained first deficiency information according to the deficiency period of the data recorded in the first recording unit for the designated period and the obtained second deficiency information according to the deficiency period of the data recorded in the second recording unit for the designated period;
- a determining unit configured to determine whether data corresponding to the deficiency period of the data recorded in the selected recording unit is recorded in the other recording unit which is not selected by the selection unit;
- a third obtaining unit configured to obtain the data corresponding to the deficiency period of the data recorded in the selected recording unit from the other recording unit;
- a complementing unit configured to complement the data in the deficiency period of the data recorded in the selected recording unit with the data obtained from the other recording unit by the third obtaining unit;
- and
- a backup unit configured to record the complemented data in the backup storage unit as the backup data.
A recording control method performed by a recording control apparatus which controls recording of data transmitted from a network camera to plural recording units, the recording control method comprising:
- designating a period of the data transmitted from the network camera to the plural recording units to be recorded in a backup storage unit as backup data;
- obtaining first deficiency information according to a deficiency period of the data transmitted from the network camera and recorded in a first recording unit for the designated period;
- obtaining second deficiency information according to a deficiency period of the data transmitted from the network camera and recorded in a second recording unit for the designated period;
- selecting one of the first recording unit and the second recording unit based on the obtained first deficiency information according to the deficiency period of the data recorded in the first recording unit for the designated period and the obtained second deficiency information according to the deficiency period of the data recorded in the second recording unit for the designated period;
- determining whether data corresponding to the deficiency period of the data recorded in the selected recording unit is recorded in the other recording unit which is not selected;
- obtaining the data corresponding to the deficiency period of the data recorded in the selected recording unit from the other recording unit;
- complementing the data in the deficiency period of the data recorded in the selected recording unit with the data obtained from the other recording unit;
- and
- recording the complemented data in the backup storage unit as the backup data.
A non-transitory computer readable storage medium which stores code of a program executable by a computer for controlling recording of data transmitted from a network camera to plural recording units, the program comprising:
- a designating process of designating a period of the data transmitted from the network camera to the plural recording units to be recorded in a backup storage unit as backup data;
- a first obtaining process of obtaining first deficiency information according to a deficiency period of the data transmitted from the network camera and recorded in a first recording unit for a designated period;
- a second obtaining process of obtaining second deficiency information according to a deficiency period of the data transmitted from the network camera and recorded in a second recording unit for the designated period;
- a selecting process of selecting one of the first recording unit and the second recording unit based on the obtained first deficiency information according to the deficiency period of the data recorded in the first recording unit for the designated period and the obtained second deficiency information according to the deficiency period of the data recorded in the second recording unit for the designated period;
- a determining process of determining whether data corresponding to the deficiency period of the data recorded in the selected recording unit is recorded in the other recording unit which is not selected by the selecting process;
- a third obtaining process of obtaining the data corresponding to the deficiency period of the data recorded in the selected recording unit from the other recording unit;
- a complementing process of complementing the data in the deficiency period of the data recorded in the selected recording unit with the data obtained from the other recording unit;
- and
- a recording process of recording the complemented data in the backup storage unit as the backup data.
