rsnapshot: New addon

- What is it?
	rsnapshot is a filesystem snapshot utility based on
	rsync. rsnapshot makes it easy to make periodic snapshots of the
	ipfire device. The code makes extensive use of hard links whenever
	possible, to greatly reduce the disk space required.  See:
	https://rsnapshot.org

- Why is it needed?
	Rsnapshot backups run multiple times per day
	(e.g., once per day up to 24 times per day). Rsnapshot is much easier
	to configure, setup and use than the borg backup add-on.  (I found
	borg somewhat confusing). Rsnapshot completes each backup very fast.
	Unlike borg, rsnapshot does not compress each backup before storage.
	During a complete rebuild, borg backup need installation of the borg
	add-on to recover archived files.  Rsnapshot backups can be copied
	directly from the backup drive. Current backups (backup.pl or borg)
	could corrupt sqlite3 databases by running a backup during a database
	write.  This add-on includes a script specifically for sqlite backups.

Thanks to Gerd for creating a first build and a nice template for me!

# This is a simple shell script to backup a sqlite database with rsnapshot.
#
# This script simply needs to dump a file into the current working directory.
# rsnapshot handles everything else.
#
# The assumption is that this will be invoked from rsnapshot.
# See:
# https://rsnapshot.org/rsnapshot/docs/docbook/rest.html#backup-script
#
# Please remember that these backup scripts will be invoked as the user
# running rsnapshot. Make sure your backup scripts are owned by root,
# and not writable by anyone else.
# If you fail to do this, anyone with write access to these backup scripts
# will be able to put commands in them that will be run as the root user.
# If they are malicious, they could take over your server.
#
# chown root:root backup_sqlite.sh
# chmod 700 backup_sqlite.sh

# If enabled, rsnapshot will write a lockfile to prevent two instances
# from running simultaneously (and messing up the snapshot_root).
# If you enable this, make sure the lockfile directory is not world
# writable. Otherwise anyone can prevent the program from running.
#

# If your version of "du" doesn't support the -h flag, try -k flag instead.

#du_args -csh
# If this is enabled, rsync won't span filesystem partitions within a
# backup point. This essentially passes the -x option to rsync.
# The default is 0 (off).
#
#one_fs 0
# The include and exclude parameters, if enabled, simply get passed directly
# to rsync. If you have multiple include/exclude patterns, put each one on a

#
#include_file /path/to/include/file
#exclude_file /path/to/exclude/file
# If your version of rsync supports --link-dest, consider enabling this.
# This is the best way to support special files (FIFOs, etc) cross-platform.
# The default is 0 (off).
#
link_dest 1
# When sync_first is enabled, it changes the default behaviour of rsnapshot.
# Normally, when rsnapshot is called with its lowest interval
# (i.e.: "rsnapshot alpha"), it will sync files AND rotate the lowest
# intervals. With sync_first enabled, "rsnapshot sync" handles the file sync,
# and all interval calls simply rotate files. See the man page for more
# details. The default is 0 (off).
#
sync_first 1
# If enabled, rsnapshot will move the oldest directory for each interval
# to [interval_name].delete, then it will remove the lockfile and delete
# that directory just before it exits. The default is 0 (off).
#
#use_lazy_deletes 0
# Number of rsync re-tries. If you experience any network problems or
# network card issues that tend to cause ssh to fail with errors like
# "Corrupted MAC on input", for example, set this to a non-zero value
# to have the rsync operation re-tried.
