Da ist mir doch gerade eingefallen, dass ich in meiner Breakout-Box (diverse Anschlüsse via Thunderbolt) noch eine 2TB M2 SSD schlummern habe und kein Backup-Laufwerk mehr besitze.

Schnell mal die Platte umpartitioniert und 512 GB frei geschaufelt. Dann die Platte als Time Machine Backup Platte deklariert und nun sichert mir mein Mac alles brav weg. (1/2)

Yesterday in the post below, I asked about backup software for MacOS and most people mentioned/recommended Time Machine.

infosec.exchange/@cliffwade/11

I sat that up, but then quickly realized that I can't use the drive for much else, and I'm not wasting a 2TB drive on 150GB of backups, so I disabled Time Machine.

Thanks to @dhry and @amerpie I've now decided to go with SmartBackup, as that seems to allow me to backup to my 2TB drive and still use that drive for other stuff just like normal. So I think this is method I will stick with, at least for now.

Infosec ExchangeCliff (@cliffwade@infosec.exchange)MacOS users... What backup software do you use on your MacOS devices? I don't need anything fancy, just something in case something happens at some point. Is Time Machine good and/or recommended? Is there something different or better that y'all recommend? #MacOS #Mac #TimeMachine #BackupSoftware #Software

MacOS users...

#TimeTravelTuesday #ThoughtExperiment: Many #Worldlets?

or in other words, fractions of #World, not the whole World. #TimeTraveler #theories often involve splitting or multiplying #universes. Time Travel events divide #spacetime into two near-identical clones. Grandfather lived or did not, you did not meet yourself or you did. But if we think this through further, its scope might not be quite so universal as typically presented.

Take 3 heavenly bodies: Mother #Earth, the #AlphaCentauri triple star system (at 4+ light years away), and #Polaris, the #NorthStar (at 400+ light years away).

Now we program our #TimeMachine to take us back one year (#retrograde) where we meet ourselves. Hi selves! This all takes place in one year. There's the original us, there's us leaving the present, and there's us meeting our past/original selves a year earlier — standard #boilerplate #scifi #movie #script.

Alpha Centauri will have to wait another 3 years before any of this information can get to there. This is related to the concept of a #lightcone which expands at the speed of light. This doesn't sound quite so much like birthing a twin universe, does it? Now what about the North Star? It will have to wait 433 years for news of our Time Travel event(s). And that's still pretty much in our tiny #celestial neighborhood.

The point is that the effects of such events are largely localized and rapidly diluted as we move farther away. This still has its paradoxical problems, but it doesn't quite feel like the whole universe dividing into two — maybe part of it (a universelet? a subuniverse?) Possibilities are that in moving further out in space-time, the effects of a Time Travel incident may be 'blurred out', as are anomalous numerical samples in the law of large #numbers. If one pours a cup of coffee into a lake, it doesn't change the color of the lake. There is a brief chaotic #glitch before it is no longer measurable.

It is tempting to imagine space-time as "stitching" itself back together. (Glitch & stitch?) Such speculations are related to #StephenHawking's "chronology protection conjecture" of 1992. And along with #blackholes, #entanglement, and other #quantum phenomena, if Time Travel is possible, then we should be looking for it at every scale. We could be surrounded by time-traveling particles everywhere all the #Time.

@Twoflower I've been stuck on Motown and vintage soul for days. Today it
will be Sinatra and the Great American Song Book. I realized as a kid that music is a way to travel through time. There's nothing wrong with
taking the time machine for a spin when you need to get away.

#timemachine

Since #macOS 15.3, network #TimeMachine fails every time (with a different file every time). The logged error looks like

Copy stage failed with error: Error Domain=com.apple.backupd.ErrorDomain Code=400 "(null)" UserInfo={NSUnderlyingError=0x8756ee400 {Error Domain=NSCocoaErrorDomain Code=512 "The file “.com.apple.backupd.mdmv499647” couldn’t be saved in the folder “default”." UserInfo={NSFilePath=<path>, NSURL=file:///<path>, NSUnderlyingError=0x8756ef120 {Error Domain=NSPOSIXErrorDomain Code=92 "Illegal byte sequence"}}}, MessageParameters=(

)}

Anyone else seeing this?

Finally got Time Machine set up again, but I'm curious about what the heckin it's doing. #Apple #TimeMachine

I opened my 15-inch M3 MBA over an hour ago, it ran a backup. It is now running another, and in that hour I have:

- Filled out a form online in Safari
- Received a couple small photos from my phone to help with said form
- That's... about all I can think of. Just a 2-3 page online form

What on EARTH could my Mac have been doing to require a > 1.1GB Time Machine backup???
