+# remote_backups
+
+## Introduction
+
+A simple shell script to retrieve selected remote server directories
+in order to integrate the remote files into the local homelab
+backup solution.
+
+Rsync is used so that only changed files are retrieved on subsequent
+runs of the backup script.
+
+The script is intended to be run from the crontab for a user that has root ssh
+key access on the remote hosts.
+
+## Configuration
+
+* bu-hosts
+
+This directory contains a file for each remote host to be backed up. The filename
+is the host's FQDN.
+
+The file for each host contains the SSH specification for reaching that host.
+
+* bu-lists
+
+This directory contains a file for each remote host to be backed up. The filename
+is the host's FQDN, with "_bu-list" appended.
+
+The file for each host contain a list of directories on the remote host to be backed
+up, one directory per line.
