Maryland man without backup sues Adobe over Premiere Pro file-eating bug
A professional photographer and long-time Premiere Pro user claims that after an update the software deleted files including non-Adobe ones. He doesn't want your sympathy, but he does want a $5 million class action lawsuit and trial by jury to blame Adobe for the problem, rather than pointing the finger at not having a reliable backup.

Professional photographer David Keith Cooper of Maryland, US, has filed a claim to take Adobe to jury trial over loss of his data through a software fault in the video-editing app Premiere Pro. He alleges that this should be a class action suit to a value in excess of five million bucks because he knows many other people who've had the same problem.
Adobe Premiere Pro is a subscription application that you pay from $19.99 per month for. An 8TB backup drive costs about $149. We're unclear how much Cooper's lawyers are charging him, but it is probably a great deal more than $19.99 per month, plus $149. You can read practically every other detail online in the filed court document that we've helpfully embedded below.
What Cooper claims happened is that he shot a lot of video. Truly, a lot -- he alleges that it was around 500 hours of digital footage that he filmed between 2010 and this terrible day in 2017.
He kept his footage on one external drive connected to his computer and on or about May 1, 2017, he installed the then latest update to Premiere Pro and edited some video. To save space on his computer's internal drive, he moved Premiere Pro's temporary Media Cache to the external to save space. He then clicked on Premiere's Clean Cache command.
He says that instead of this wiping temporary Premiere files, it permanently erased any number of video files and documents from that disk.

Detail from David Keith Cooper's legal filing
We've all lost data and we have all sworn at software that's erased it for us -- we're looking at you, Microsoft Word -- so we do all recognize Cooper's pain. Only, zoom back to the description of him: he's a professional photographer. The legal filing actually says he's "an experienced and sought-after commercial photographer, videographer, and video editor."
The trouble is, if we or you or anyone else searches for him, the easiest thing you can find that is definitely him is this lawsuit. He's just an experienced photographer who in seven years apparently never made any reliable backups. Perhaps he didn't know how: let us help him out there.
He says he's lost his data because of Adobe but if he shot it on assignment, he's actually lost his client's data. If you're a client seeking after a photographer, we feel we can be sure this one will backup files in the future. And if he wins his case, he'll be able to buy around 30,000 8TB drives to store it on -- assuming the lawyers don't take most of it.
And, in case you were wondering, the terms of using the Adobe software are pretty clear about the company not being responsible for data loss for any reason.

Nobody should lose data
According to Adobe's own blog, this bug is true. It was possible back in May 2017 that clearing the cache could wipe non-Premiere files so it is also possible that this how Cooper lost so much work.

To me this is something akin to Ford having a steering defect and someone getting injured in a crash because they weren't wearing a seatbelt. Should they have their seatbelt on? Definitely, but the steering defect still caused the crash.
Deleting your personal files then saying 'well, you should've had a backup' is irresponsible, especially from a trusted company like Adobe. I fully support his effort and I hope he wins the five million.
Okay, I'm going to side with Mr NoBackup on this one.
Yes, he should have had a backup, but let's look at what happened here.
Adobe erased files that had nothing to do with their application!
What sort of poor software craftsmanship is that?? They are the worst of the worst.
Unfortunately, like every other software vendor, there is a clause in the license that says Adobe does not guarantee the software will work or is fit for purpose.
Moving the cache folder seems unnecessary; if your internal storage is too small, upgrade it or put your scratch files on another external. Generally speaking, dragging folders out of Apps is risky. Links get broken or moved and weird things can happen.
The article doesn’t say what kind of Mac he had or what version of the OS was running, so who knows. Maybe he will win, but in the end, just back up your stuff...it’s so easy and cheap to do.
Walk out. Take your wallet with you.
Find alternatives. Expand your mind.
Back up.
Often.
Lots.

500 hours of 40Mbps HD video = 9,000 GB
WD 2 TB external hard drive w/USB 3 can be had for $64 on Amazon.
There are so many ways to back up: Cloud storage, external HD, thumb drives, or simply zip the folder at the end of each editing session.
There is no excuse not to be backed up, especially on a big project. I use Time Machine, but he was probably using Windows.
This clown had data from 2010 to 2017 on a single drive? That's it? He's not a photographer. He's a rookie. That's the problem with adults like him... it's always someone else's fault. There are a multitude of online options that would back up his data, and keep that data offsite. It's inexcusable in today's inter-connected world that he could not have taken the 1 hour out of his life to get his backup affairs in order.
Client: Okay... you didn't back them up?
Client: "hmmmm......" *whispers to friend* "Is this guy legit?"
On Dropbox you have to deliberately move file into a the deleted files folder and if you really want to delete them you select the file to permanently remove.
I have a buddy who is a forensic computer engineer who can undelete just about any file and he doesn't charge that much either.
My attorney told me that any lawyer who specifies the amount of damages in advance of a trial or settlement is incompetent.
