There are four times in my life I have suffered regrettable data loss incidents.

The first was when the telephone pole outside our house was struck directly by lightning. Not only was it the loudest thing I have ever heard, the current surged through the telephone line, into the internal fax modem, and fries everything within its vicinity. I was 10. I did have backuos, but only only floppy and they didn't cover everything.

The second was storing data in OneDrive - a change to their terms surrounding "lifetime" unlikely noted storage, combined with a client that was unusably slow to download and a deadline for data retrieval meant that I lost most of my files.

The third was SD card failure in digital camera on holiday, the controller chip died catastrophically, leaving the card completely unrecognised. It was a brand new Sony 128GB card, manufactured by Toshiba, and it seemed to be a common issue. I now shoot to two cards simultaneously.

And the fourth time was ... Performing a backup. An errant script deleted the source content, but I'd also deleted the existing backup to free up space for the new backup. I've been weary of using rewritable media for some time now as a consequence, but I think backups themselves are high risk activities.

I would say you didn't get quite the right lesson from the fourth one. Rewritable devices are fine, but have (at least) one backup completely unplugged while you update another backup.

>I did have backuos, but only only floppy and they didn't cover everything.

This made me remember the time during the 90s when I lost all my BASIC programs due to a hard disk crash, and seeing me sitting sad, my mother handed me a bunch of floppies and asked me to see if they contain something useful.

And turned out that it had all the programs! I took the backups and forgot about that. Apparently that is one of the hard things with backups. You need to track them...

I had a similar experience with a Chinese cloud storage provider. They didn't even give a convenient way to export the data. And the client throttled download to like 100KB/s. I luckily was able to parallel download by running the client on several VMs...

> An errant script deleted the source content, but I'd also deleted the existing backup to free up space for the new backup.

Sounds like the backup workflow is fundamentally flawed... But I also have the fear that the backup program with root privileges can go off the rails... So I keep my backup job as simple as just running restic with some systemd restrictions.

OneDrive...

So much fail in one single product.

>I've been weary of using rewritable media for some time now as a consequence

I briefly considered using bluray disks as a backup for my photos and other critical docs. But getting a decent bluray burner seems not so easy these days with most production winding down. Next best thing looks like the "object lock" feature on object store services that prevents deleting objects for a certain time.

Since we’re talking about it: anyone backing up their iCloud photos? If so, how?

For digital media we really need a good stable archival storage solution. Nothing on the market right now for ordinary people.

>I now shoot 2 cards simultaneously

A very lovely change over the last 8 years or so lol. I came up in film during the DSLR revolution. 5D2’s/7D’s/Rebels (i series) years.

8bit 420 nasty aliasing recording on single cards and praying baby. Magic lantern booted on those same SD’s!
