Plan today... Safe for tomorrow!

The tip itself is very simple: Back up your data! Your photos don’t really exist until they exist in at least two places. Hard Drives fail. Optical Discs rot. Floppy Discs are tiny. So what do you do? You make sure that you have multiple copies of every single one of your important files. And you really should have one backup copy of all your important data that is quickly and easily accessible, and another copy that is stored at an off-site location that can’t be affected by the same flood, fire, or theft that could get the other two copies.

Hard Drives are cheap. If you just consider your backup drives as part of your photographic kit (just like the camera, lenses, and these days the computer too) then you will be in a much better place mentally when it comes to buying them. You need all of these things in order to successfully create, manipulate, and preserve your images. It’s just that simple.

How to Backup

This is the long part. I’m not going to tell you how to backup your photos and other important documents. That’s up to you. But I will tell you what I do, and why I do it. Unfortunately, because my system is so robust it is also quite complicated. And that takes a long time to describe…

I recognize that most people won’t even come close to doing what I do. But I hope you will do some of it, because (say it with me) “All Hard Drives Fail“. Even if you only do some of this it will be much more likely that your data is safe.

•First of all I keep the original copies of all of my important documents, data, and recent photos on my laptop. I would prefer to keep absolutely everything on my laptop, but laptop hard drives simply aren’t available that are big enough to do so; therefore, I can only keep my recent work on my laptop and older stuff must be stored elsewhere.
•My laptop and my desktop are connected via a network and I do automatic backups of all my important documents so that they are readily available on either machine. The frequency of these backups varies depending on the type of data.
The automatic backup is done using AJC Directory Synchronizer. This is a very powerful program that allows you to choose exactly what you want to backup and where you want it to go. It is easily scheduled via the Windows task manager so you can create multiple jobs with appropriate frequencies for each job. I have used many similar pieces of software over the years and I’m much happier with this one than I was with any of the others…

•I have 2 D-Link DNS-323 Network Attached Storage (NAS) cases that each contain 2 Hard Drives. One of the drives in each NAS contains my entire photography library (including the recent work from my laptop), which I can access directly over the network from either computer using Adobe Lightroom or Windows Explorer. The other drive in each NAS contains all of my other data and documents. I do an automatic backup every week to copy everything from the primary NAS to the secondary NAS. This backup syncs any additions, deletions, or changes to any files on the primary. I do this weekly because that provides a nice buffer in case I make a mistake on either of the computers and it gets propagated to the primary NAS before I catch it. I then have a few days to recover any necessary files from the secondary NAS.
•This next part may sound crazy to some of you, but it is actually the most important part of my backup strategy… I use a portable USB drive that contains another copy of absolutely everything, and I store this drive off-site. This protects me in case of fire, flood, or any other major disaster that would impact my house, and which could potentially destroy all of the other backup copies at the same time. I only update this drive every few weeks, so there is always some exposure to losing my most recent files, but I have years worth of work stored on this drive that will always be safe.
This drive can be stored at your workplace, at a friends house, in a safety deposit box, or even in your vehicle (as long as you don’t park it in the garage attached to your house!). The important part is that it must be an off-site backup, and therefore you have to get it out of your house. With this drive stored somewhere else, my absolute worst case is that I lose a few weeks worth of data.

Note that I even go to the extreme of taking my secondary NAS off-site prior to bringing in my external drive!


Note that if you have a relatively small amount of data, a system like this could easily be created by using 2 inexpensive USB Hard Drives. These are readily available for under $100 if you need 1TB or less. You could use one drive as your primary backup and the other as the off-site backup. In fact this is exactly what I did for a long time before my storage needs outpaced the USB drives that I had. One benefit of using the NAS cases is that they are directly connected to my gigabit ethernet network, and I really like the performance and speed that the NAS is capable of.

The beauty of this system is that it can be easily upgraded by replacing the portable hard drives as your storage needs get bigger. These drives get bigger, faster, and cheaper all the time. Depending on how much storage space you need, you may never have to do this. Or you might need to start off with a multi-bay NAS right off the bat if you already have lots of data and you don’t have a good backup system.

So even if you only get one backup drive, and even if you only backup your data every once in awhile, I hope you are doing something. Do whatever works for you! Feel free to drop me a line if you need some help setting up your backup system!
