Nice poetry. Store that there.

Actually he also uses the cloud. The problem was he had bit rot in many images from a certain time period and didn’t realize it, so he kept backing up bit rot images.
I have installed a Samsung solid state drive in my computer. It came with software that allows for "over provisioning," which reserves fallow space for use down the road when and if storage locations start failing. Diagnostics run periodically to determine whether that is happening, and I run more comprehensive diagnostics periodically. You can do some of the same thing with the Windows disk utilities, but they don't seem to be nearly as robust.
None of this is a substitute for having a backup process and multiple copies of important files. But it does let you know when things start going wrong, maps around bad storage locations, and, to a limited extent, corrects corrupted files. By the way...those same diagnostics need to be run on the backups from time to time.
Protecting data is a multi-dimensional endeavor.
"Bit Rot" sounds so much cooler than corrupted data.
I thought bit rot pertained to CD/DVD media, a type of data corruption due to degradation in the media itself.
Last I knew hard drives don't exhibit bit rot.
People will call it what they want though.
It could happen to anyone. There are no guarantees. I backup to 3 external hard drives and the cloud and an additional image backup.
I never had a problem, however, as careful as I am, it could still happen although the odds are low.

A short synopsis in the post of what happened would be good, not everyone wants to go watch the video.
So the OP should go to extra effort so you can be lazy?

I have always tried to tell people that when it comes to digital photos always have more than one backup.
Usually suggest at
Least three copies of the photos with one being off the premises.
I back up my hard drive regularly to my home nas which is a raid configuration for the redundant storage which gives me a dual copy of the hard drive as a guard against hard drive failure
I also have the computer as well as my phone configured to automatically make a backup for all my photos to my Amazon pictures account.
I have prime so unlimited photo storage is free.
Also once a month I will take another backup for my hard drive and swap it out for the previous one in the safe at my daughter's house.
This seems like excessive but you have to consider that our family pictures were lost in a house fire some years ago and that's why I emphasize to have an off premises backup.
Hard drive circuitry will not withstand a fire so your pictures would still be lost if only an on premises backup.

Using a NAS for backup is a waste of NAS.

And if Tony had a DR copy in a MAJOR cloud provider such as Amazon S3 (or Google or Microsoft or Apple) with versioning or on a storage system with parity checking/ECC on reads AND writes or on MDisk for archive, he’d have those photos today. This “bit rot” thing is just something you never see on enterprise class storage / architecture. I sold & designed storage for the largest storage companies in existence for 25+ years, and I NEVER saw a case of data lost to “bit rot”, but I surely have seen it lost to all manner of operator error, environmental issues, double drive failures and restore from backup failures.
The worst I ever saw was an unskilled contract admin wipe 384 TB of data with a single keystroke on a shared file system he wasn’t familiar with. The data was eventually recovered after 3 months by tearing down the entire system, shipping it physically back to the mirrored system, reimageing it and shipping it back - cost a fortune.
And if Tony had a DR copy in a MAJOR cloud provide... (

You have deep expertise. I do back ups and have a cloud back up, but still feel like I don't fully understand the whole process and what is cutting edge. Perhaps some education or a web site or something? I imagine a posting would be quite a lot of work. But I think we all would benefit.

Paul, I did not know that you were into poetry and not bad at that. Have a good day.

I suppose that's one way to look at it.
The other would be so people don't have to go watch the video if they don't want to.
Pick one.
Oh, wait ,you did.

You are too generous. Even a stopped clock shows the right time twice a day.
