Final tar(ball) and encryption

[Ryan Scott Lewis]

Tar the final collection of backup files into a single file:

• Optionally compress?
  • Choose to compress only the final tar rather than the archive? Or both? Is there any benefit to compressing the final tar?
• Encryption stage comes before or after this stage? Same questions as compression on this final tar.

On a side note, all compression and encryption should be optional, regardless of order of operations.
