3 * Bacula Director -- restore.c -- responsible for restoring files
5 * Kern Sibbald, November MM
7 * This routine is run as a separate thread. There may be more
8 * work to be done to make it totally reentrant!!!!
10 * Current implementation is Catalog verification only (i.e. no
11 * verification versus tape).
13 * Basic tasks done here:
15 * Open Message Channel with Storage daemon to tell him a job will be starting.
16 * Open connection with File daemon and pass him commands
18 * Update the DB according to what files where restored????
