"No files" in Bacularis for Jobs

greetings

today a customer asks me for a list of files in a directory at a given 
date in february

I open Bacularis-5.0.0, and want to use "Restore" to browse the database:

there's a job backing up the samba-share containing the relevant 
directories.

What scares me:

I choose a FULL backup but when I come to "Step 3 - select files to 
restore", it tells me:

"It seems that there is no files for choosing or file records in 
database for this job has been purged (file retention period expired)"

So the Job is in the DB but "without content" ?

I assume the files are on tape anyway ... right now the tapes are 
off-site so I can't try ... but I assume I could run some full restore 
and search my files in there?

-

Would the catalog contain that information?

I backup the catalog also even that someone told me here it wouldn't be 
necessary anymore ...

I have a catalog backup from early march ...

thanks for any pointers here.

Seems I have to review my setup ...
