From 5c9df935636c6b5610a0d1f2bf3ed8dfcd10c856 Mon Sep 17 00:00:00 2001
From: Sam Chudnick <sam@chudnick.com>
Date: Sun, 28 Nov 2021 23:13:19 -0500
Subject: Combined borg-onsite and borg-offsite scripts into a single script
 that takes an argument to specify the location. Reorganized script to use
 variables to reduce redundant strings. Added automated retrieval of
 repository password via pass. Removed --list from borg create options and
 redirect output to log file.
