i've finally solved my problem, thanks to all (in particular to Les & Jeffrey).
The method is not perfect, but it works :-D.
Here the host pl file:

$Conf{XferMethod} = 'rsync';
$Conf{ClientNameAlias} = '127.0.0.1';
$Conf{FullPeriod} = '0.97';
$Conf{RsyncShareName} = [
  '/media/smbfs'
];
$Conf{BackupFilesOnly} = {
  '*' => [
    '/additional_path/filename.extension'
  ]
};
$Conf{RsyncClientCmd} = '$rsyncPath $argList+';
$Conf{RsyncClientRestoreCmd} = '$rsyncPath $argList+';
$Conf{DumpPreUserCmd} = '/bin/sh /usr/src/predump.sh
//10.0.5.3/tempshare $share /etc/backuppc/.smb_credentials
additional_path filename.extension';
$Conf{DumpPostUserCmd} = '/bin/sh /usr/src/postdump.sh $share
additional_path filename.extension';
$Conf{UserCmdCheckStatus} = '1';
$Conf{RestorePreUserCmd} = '/bin/sh /usr/src/mount_smbfs.sh
//10.0.5.3/tempshare $share /etc/backuppc/.smb_credentials';
$Conf{RestorePostUserCmd} = '/bin/sh /usr/src/umount_smbfs.sh $share';

(i've just changed from original host pl file:
additional_path : that's the directory in smb share where file to
backup is stored;
filename.extension : that's the chosen name for the file (the name
that will appear in browsing backup)
)

I've changed RsyncClientCmd and RsyncClientRestoreCmd (to make work locally).
I've created for DumpPreUserCmd a script; that script runs another 2 scripts:
- one to mount the remote share in the mount point defined ($share) -
(script used also in RestorePreUserCmd )
- one to rename the last modified file that is in mount point +
additional path as filename.extension; old file name is saved as .pid
empty file (that helps me also to verifiy if backup is running,....);

Then starts rsync backup.

I've than created for DumpPostUserCmd a script; that script runs
another 2 scripts:
- one to rename the filename.extension to original file name and
remove .pid file and
- one to umount the remote samba share (script used also in RestorePostUserCmd).

For smbmount/smbumount i've configured sudo for backuppc user.

In this way, i have always the same file name, and that file is always
the last one created (or edited).
If it could help, i can pastebin scripts created.

Regards
M
