+This is a collection of simple backup scripts for a few servers I have administered.
+Some use exclusion files to filter what to backup.
+
+There is also an "audit" script, that can be used by crontab to regularly send server
+details (e.g. disk usage) to Slack.
+
+Be warned, that these scripts are primitive. They do not stop Minecraft servers from
+auto-saving prior to backup. This might result in a partial or corrupted world when
+restoring from such a backup.

 ## `home`
 
-The `home.sh` target is for user files which may be gigabytes to terabytes larger than the system backup. This requires the username of the home directory to backup and **excludes** all kinds of transient files, including but not limited to:

 ## `mysql.sh`
-This uses `mysqldump` to take and bzip2 a dump of given MySQL databases on the system's installation. This target requires the use of a `.cnf` file that has the password for the MySQL user `root`, in order to perform the dumps. See http://dev.mysql.com/doc/refman/5.1/en/password-security-user.html for more information.
