Backup is one of those hygiene subjects we would rather not think about or talk about. But it is important. You need to backup intentionally and consistently.
Film days
Back in the “good ole’ days of film”, (they weren’t really the good days) we never had to worry about backup. The developed film was the permanent physical backup.
All we had to worry about was storing it properly and in a fireproof location. These days, finding a fireproof location is more of a challenge. Photographers who had some exceptionally valuable images might have duplicate film images created and stored in a vault or safety deposit box.
I have many filing cabinet drawers full of slides and negatives. Sadly, I never look at them. Partly because they are old and I have improved a lot and changed my interests some. But mainly because, being physical instead of digital, they are hard to search and locate. I can’t see me ever taking the time to scan them all.

Digital days
I expect the majority of you reading this shoot digital exclusively. I know I do. Digital has many advantages. Obviously, since it has almost completely taken over photography.
But digital. has a huge disadvantage. The image data is ephemeral. It has no physical presence. If we delete the file, it is gone. Permanently, if it is not backed up.
What would happen if your main image disk said “poof” and a little smoke leaks out? All your images are gone unless they are backed up. As if they never existed. Most of us would consider this a disaster.

Disks fail
But disks are very reliable, aren’t they? We can find published reliability numbers like 1,000,000 hours MTBF (mean time before failure). That sounds very safe.
But those are projected statistics for large numbers of disks. My particular drive could fail tomorrow. And they do. I am sitting here looking at a stack of 11 failed disk drives that I am waiting to get in the mood to take outside and smash with a sledge hammer.
SSD drives seem to be more reliable than rotating magnetic disks. Seem to be. But let me reveal a dirty secret about solid state drives: they are so unreliable that they are extensively engineered to mask their failures. Bits fail all the time. Whole sections of an SSD can go bad. The drives have sophisticated error correction algorithms built in to allow for this and keep them functioning with no apparent data loss. Kind of like RAID built in.
They haven’t been around long enough to have conclusive data, but in general, SSD’s seem to be more reliable than magnetic disks. But they fail.
Don’t get me wrong, SSD’s are an improvement, and I will switch when prices go down enough for the quantity of storage I need. My point, though, is that SSD’s still fail. They are not some magical device you can forever trust your valuable images to and be guaranteed safe.

Clouds fail
So, the obvious solution seems to be put all your data in the cloud. Right? Let somebody else handle the storage management.
There are problems. Cloud storage gets pretty expensive in the quantities most serious photographers need. And keep in mind that this is an ongoing expense.
And how fast is your internet for upload speed? I am fortunate to be served by one of the best internet providers in the nation. Theoretically, in perfect conditions, I could upload a Terabyte of data to the cloud in a little over 3 hours. IF everything is perfect and if the cloud storage could accept data that fast. Previous internet providers I had would take weeks to upload this much data, because upload speed was much slower than the download speed.
But even if you successfully get your data into the cloud, it is now at the mercy of the service you use. They can go out of business, or change business models, or raise prices. If you use Azure or the Amazon cloud your data is probably pretty safe. Maybe even Adobe. But you have no control. I like to control what is important to me.
Lightroom cloud?
Maybe the Lightroom cloud storage is the right answer for you. It is for some. If you are just starting out in photography, it may be ideal for you.
The latest data I saw said Adobe offers up to 1TByte of storage. That’s the tip of the iceberg of the 10 TBytes of image data I currently have. If they offer that much storage, it would be expensive. If I work an image in Photoshop and composite multiple images and use lots of layers, it can exceed 4GBytes for one image. That eats up terabytes fast.
And to access your images, you must have internet access. I have a fantastic internet provider, but outages still happen occasionally. Yes, Lightroom stores a highly compressed small version of images locally on your computer, but that does.not seem good enough to me.
There are some other reasons I will not use the cloud version of Lightroom, but they are not directly related to backup problems.

Seize control
Digital image data is a blessing and a curse. There are significant advantages to it, but never forget, it can easily go away.
So we must proactively manage our data. That means backup. An aggressive, thorough backup plan that you monitor. This is a time to be paranoid.
If you are on a Mac, step one is to plug in a large external disk and enable Time Machine. This is the automatic backup system built into Macs. It is so good that it may, all by itself, be a reason to switch to Macs. I’m not kidding. Make sure it is configured to also backup your image data.
I will give you a glimpse into how paranoid I am in protecting my data. Even though my main image storage is a RAID system, my data is backed up hourly to Time Machine, and daily to two external disks, one of which is a network attached RAID drive. Every week I also make a copy that I keep offsite, and about once a month I make another snapshot of my data that is kept offline and safe.
Some local backup with a layer of cloud backup is a feasible alternative now, but so far, I have chosen not to go that route.
That sounds like a lot of work, but except for the weekly and monthly offsite backups that are not normally physically connected, it is all automatic. Thank you Time Machine and Carbon Copy Cloner. The CCC plug is FYI and just to let you know the specific tool I use. I get no consideration for recommending it.

Make it automatic
I admit, I am paranoid about my digital assets. They have been created over a long time with lots of work and expense, and they are precious to me. I do not intend to loose them because of a preventable accident.
Earlier I mentioned a stack of 11 failed disk drives. That is just the current accumulation. Many more have failed over my time of being a digital photographer. But I have never lost a file because of a disk failure.
I believe a well thought out, in depth backup plan is a must for any serious photographer today. Perhaps I overdo it. But I am not willing to take the risk of doing too little.
I have tried to be clear that this is just my way of doing backup. Like all photographic workflow decisions, it is usually a personal choice. Yours may be lighter weight or more rigorous. Do what works for you. But do it.
Do not let backup be something you might remember to do once in a while, if you think of it. You won’t think of it at the right time. The clock is ticking.
