Help with adding to tar filenames

Hi there, i have been working on a backup script and have it just about working, the only problem im left with is that my filenames for my backups are all the same are replacing one another when backing up.

currently i have
BACKUP_FILE=backup_$(date +%d%m%y).tgz
but would like something like
BACKUP_FILE=backup_(filename)_$(date +%d%m%y).tgz
to help with identification

any help is appreciated and my code is posted below.

Code:

    #!/bin/bash
   
  clear
   
  VALID_PATH=0
  BACKUP_FILE=backup_$(date +%d%m%y).tgz
  BACKUP_DIR=.backup/
   
  [[ ! -d $BACKUP_DIR ]] && mkdir -p $BACKUP_DIR
  echo 1 Perform A Directory Backup
  echo 2 Perform A File Backup
  echo 3 Restore From Backup
  echo 4 Exit Program
   
  read OPTION
   
  case $OPTION in
   
  "1") echo You Selected Option 1
  echo Please Enter The Directory You Wish To Backup
  read SOURCE
   
  while [[ $VALID_PATH -eq 0 ]]
   
  do
   
  if [[ -d "$SOURCE" ]]; then
          VALID_PATH=1
          BACKUP_FILE="$BACKUP_DIR""$BACKUP_FILE"
  else
          echo This Path Is Invalid
          echo Please Enter A Valid Path
          read SOURCE
  fi
  done
  tar -czvf $BACKUP_FILE $SOURCE && echo "Backup Done" || echo "Backup Failed"
  ;;
   
  "2") echo You Selected Option 2
  echo Please Enter The File You Wish To Backup
  read SOURCE
   
  while [[ $VALID_PATH -eq 0 ]]
   
  do
   
  if [[ -f "$SOURCE" ]]; then
          VALID_PATH=1
          BACKUP_FILE="$BACKUP_DIR""$BACKUP_FILE"
  else
          echo This Path Is Invalid
          echo Please Enter A Valid Path
          read SOURCE
  fi
  done
  tar -czvf $BACKUP_FILE $SOURCE && echo "Backup Done" || "Backup Failed"
  ;;
   
  "3") echo You Selected Option 3
  echo Contents Of The Backup Directory
  ls $BACKUP_DIR
  echo Please Enter The Name Of The File You Wish To Restore
  read RESTORE_FILE
  RESTORE_FILE="$BACKUP_DIR""$RESTORE_FILE"
   
  while [[ $VALID_PATH -eq 0 ]]
   
  do
  if [[ -f $RESTORE_FILE ]]
  then
  VALID_PATH=1
  else
  echo This Path Is Invalid
  echo Contents Of The Backup Directory
  echo
  ls "$BACKUP_DIR"
  echo
  echo Please Enter The Name Of The File You Wish To Restore
  read RESTORE_FILE
  RESTORE_FILE="$BACKUP_DIR""$RESTORE_FILE"
  fi
  done
   
  echo
  echo The File $RESTORE_FILE Will Be Used To Perform A Restore
  echo
  tar -xzvf $RESTORE_FILE
  ;;
   
  "4") echo Goodbye
  exit 0;;
   
  esac
   
  if [ $OPTION -eq 1 -o $OPTION -eq 2 ]; then
  echo
  echo SUCCESS!
  echo
  echo The Following Files Were Backed Up To $BACKUP_FILE
  echo
  tar -tf $BACKUP_FILE
  elif [ $OPTION -eq 3 ]; then
  echo
  echo SUCCESS
  echo
  echo Your Files/Directories Were Restored
  fi

smbtar

SMBTAR(1)                                                          User Commands                                                         SMBTAR(1)

NAME

       smbtar - shell script for backing up SMB/CIFS shares directly to UNIX tape drives

SYNOPSIS

       smbtar [-r] [-i] [-a] [-v] {-s server} [-p password] [-x services] [-X] [-N filename] [-b blocksize] [-d directory] [-l loglevel] [-u user]
        [-t tape] {filenames}

DESCRIPTION

       This tool is part of the samba(7) suite.

       smbtar is a very small shell script on top of smbclient(1) which dumps SMB shares directly to tape.

OPTIONS

       -s server
           The SMB/CIFS server that the share resides upon.

       -x service
           The share name on the server to connect to. The default is "backup".

       -X
           Exclude mode. Exclude filenames... from tar create or restore.

       -d directory
           Change to initial directory before restoring / backing up files.

       -v
           Verbose mode.

       -p password
           The password to use to access a share. Default: none

       -u user
           The user id to connect as. Default: UNIX login name.

       -a
           Reset DOS archive bit mode to indicate file has been archived.

       -t tape
           Tape device. May be regular file or tape device. Default: $TAPE environmental variable; if not set, a file called tar.out .

       -b blocksize
           Blocking factor. Defaults to 20. See tar(1) for a fuller explanation.

       -N filename
           Backup only files newer than filename. Could be used (for example) on a log file to implement incremental backups.

       -i
           Incremental mode; tar files are only backed up if they have the archive bit set. The archive bit is reset after each file is read.

       -r
           Restore. Files are restored to the share from the tar file.

       -l log level
           Log (debug) level. Corresponds to the -d flag of smbclient(1).

ENVIRONMENT VARIABLES

       The $TAPE variable specifies the default tape device to write to. May be overridden with the -t option.

BUGS

       The smbtar script has different options from ordinary tar and from smbclient's tar command.

CAVEATS

       Sites that are more careful about security may not like the way the script handles PC passwords. Backup and restore work on entire shares;
       should work on file lists. smbtar works best with GNU tar and may not work well with other versions.

DIAGNOSTICS

       See the DIAGNOSTICS section for the smbclient(1) command.

VERSION

       This man page is correct for version 3 of the Samba suite.

SEE ALSO

       smbd(8), smbclient(1), smb.conf(5).

AUTHOR

       The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.

       Ricky Poulten wrote the tar extension and this man page. The smbtar script was heavily rewritten and improved by Martin Kraemer. Many
       thanks to everyone who suggested extensions, improvements, bug fixes, etc. The man page sources were converted to YODL format (another
       excellent piece of Open Source software, available at ftp://ftp.icce.rug.nl/pub/unix/) and updated for the Samba 2.0 release by Jeremy
       Allison. The conversion to DocBook for Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for Samba 3.0 was done by
       Alexander Bokovoy.
