+
+Create a backup for <server>, defaults to daily. Calls <server>/backup.sh
+on the remote host and saves the stdout. It's up to the server's
+specific backup script to determine the specifics of that format. Tarballs
+are suggested, but snapshots, cpio archives, etc can all be used.
+
+Where [opts] are one of:
+
+-ssh_conf <filename> # For ssh configuration i.e. -F flag on ssh
+-ssh_key <filename>  # SSH key to use, passed in as -i to ssh
+-type <daily|monthly|weekly> # Passed to the subscript, and changes output dir
+-suffix <suffix> # Defaults to 'tar.zst', but could be anything, should match
+                 # the output of the server's specific backup script
+-force # Normally we bail if a backup exists, this will force overwrite
+
+Normal usage is that weekly and monthly backups are full, and the daily
+backups only include files that were changed in the past 24 hours, usually
+via find command and piping a list of input files to tar.
+
+A separate ./cleanup.sh script can take care of removing the old backups
+on a schedule that you prefer.
