Information processing apparatus, file management apparatus, and file management system
An information processing apparatus, includes a query unit that requests a query for a file to a device in a transmission destination or a transmission source based on a transmission or reception history of the file, in response to a restoration instruction to restore the file from a terminal device, the restoration instruction being made after a deletion instruction to delete the file is made at the terminal device; and a file restoration unit that restores the file by acquiring the file from the device storing the file in a case where the file is found to be present in the device in the transmission destination or the transmission source as a result of the query.
1. A file management system comprising:
a first file memory, belonging to a first network, that stores a file, the file being uniquely identified; and
a first file management apparatus belonging to the first network, the first file management apparatus including
a first history memory that stores a first history of transmission, reception, and deletion of the file performed in the first network; and
a first processor programed to:
receive, through the first network, a restoration instruction to restore the file from a terminal device belonging to the first network, the restoration instruction being made after a deletion instruction to delete the file is made at the terminal device;
in response to the received restoration instruction, send a request for a query for a presence of the file to a second file management apparatus belonging to a second network including a transmission destination or a transmission source based on the first history stored in the first history memory, the second file management apparatus including a second processor and a second history memory that stores a second history of transmission, reception, and deletion of the file performed in the second network; and
perform control to restore the file by acquiring the file from a second file memory belonging to the transmission destination or the transmission source storing the file in a case where the file is found to be present in the second file memory as a result of the query.
2. The file management system according to claim 1 , wherein
in response to a notification that the file is not present in the transmission destination being received, the first processor performs control to acquire the file from another transmission destination to which the transmission destination transmits the file.
3. The file management system according to claim 1 , wherein
the first history memory stores information on a creator that creates the file, and
the first processor requests the query for the file to the creator.
4. The file management system according to claim 1 , wherein
the first history memory stores a time at which the file is transmitted, and
the first processor requests the query to a latest transmission destination of the file.
