I've often used
The -u flag only copies files if source is newer (ie 'update'), and you may already be familiar that -R means recursive (scans through subdirectories too).
I often include -v flag (verbos) too so you get a list of all the files being copied. thus, if you wanted the process logged, then you can redirect the output to a log file:
I must emphasise that I've not used this in a production environment though - only for controlled "offline" back ups. (I use ZFS snapshots on the production server). So there may be a number of disadvantages to cp -u compared with the suggestions earlier in this thread.
I want to backup two important files everytime they are modified. How would I write a bash script that would check the dates of my zip files and my data files and only create a new zip file if the zip file is older than the two data files?
Thanks,

IRSEND(1) User Commands IRSEND(1)NAME
irsend - basic LIRC program to send infra-red commands
SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...]
DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
as TV boxes, HiFi sets, etc.
DIRECTIVE can be:
SEND_ONCE - send CODE [CODE ...] once
SEND_START - start repeating CODE
SEND_STOP - stop repeating CODE
LIST - list configured remote items
SET_TRANSMITTERS - set transmitters NUM [NUM ...]
SIMULATE - simulate IR event
REMOTE is the name of a remote, as described in the lircd configuration file.
CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.
NUM is the transmitter number of the hardware device.
For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:
LIST "" "" - list all configured remote names
LIST REMOTE "" - list all codes of REMOTE
LIST REMOTE CODE - list only CODE of REMOTE
The SIMULATE command only works if it has been explicitly enabled in lircd.

irsend SET_TRANSMITTERS 1 3 4
irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"
FILES
/etc/lirc/lircd.conf
Default lircd configuration file. It should contain all the remotes, their infra-red codes and the corresponding timing and wave-
form details.
DIAGNOSTICS
If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
"irsend: could not connect to socket"
"irsend: Connection refused" (or "Permission denied").
