Restore of data

Hi Guys,

We got a restore request for one of the client, where she wants an entire directory to be backed up. The date mentioned is of 10 DEC, but when we checked it in the schedules we found out that there was no full backup taken in that place, instead of that we are getting cumulative and differential. Can you please help me on getting some of the reports;

1) As this particular server is moving on tapes, how to check on which tapes has the backups been written.

2) And also, what kind of backups has been written to the tapes related to this client.

Please giude me on this. Thanks in advance.
