You can add several files / directories to go into the same archive at the end of the tar command:
Code:
tar cf arc /opt /var /etc

or you follow the route you already took in above: cd to the target directory, and tar -r the files in question. man tar is a very valuable source of info for you.

. . . and can you tell me what braces you mean?
i have no knowledge of this
Try
Code:
backup_file="${backup_file}.gpg"

Expansion will stop at the dot anyhow, but for you to be on the safe side in the future when there might be no dot use the braces.

NAME
gpg-zip - Encrypt or sign files into an archive SYNOPSIS
gpg-zip [options] filename1 [ filename2, ... ] directory1 [ directory2, ... ] DESCRIPTION
gpg-zip encrypts or signs files into an archive. It is an gpg-ized tar using the same format as used by PGP's PGP Zip. OPTIONS
gpg-zip understands these options: --encrypt -e Encrypt data. This option may be combined with --symmetric (for output that may be decrypted via a secret key or a passphrase). --decrypt -d Decrypt data. --symmetric -c Encrypt with a symmetric cipher using a passphrase. The default symmetric cipher used is CAST5, but may be chosen with the --cipher-algo option to gpg. --sign -s Make a signature. See gpg. --recipient user -r user Encrypt for user id user. See gpg. --local-user user -u user Use user as the key to sign with. See gpg. --list-archive List the contents of the specified archive. --output file -o file Write output to specified file file. --gpg gpgcmd Use the specified command gpgcmd instead of gpg. --gpg-args args Pass the specified options to gpg. --tar tarcmd Use the specified command tarcmd instead of tar. --tar-args args Pass the specified options to tar. --version Print version of the program and exit. --help Display a brief help page and exit. EXAMPLES
Encrypt the contents of directory 'mydocs' for user Bob to file 'test1': gpg-zip --encrypt --output test1 --gpg-args -r Bob mydocs List the contents of archive 'test1': gpg-zip --list-archive test1 DIAGNOSTICS
The program returns 0 if everything was fine, 1 otherwise. SEE ALSO
gpg(1), tar(1), The full documentation for this tool is maintained as a Texinfo manual. If GnuPG and the info program are properly installed at your site, the command info gnupg should give you access to the complete manual including a menu structure and an index. GnuPG 2.0.15 2010-07-05 GPG-ZIP(1)
