Red grouse blending in (almost) on the high heath moors near Black Tor/Lost Lad. #peakdistrict #pickdistrictnationalpark #birdphotography #nature #hiking https://www.rspb.org.uk/birds-and-wildlife/red-grouse
View of Derwent/Ladybower reservoir +- 5m below normal. Note the uncovered remains of one the houses destroyed for the building of the dam. In the background the Derwent Edge towers over the rolling heath and farmland. #peakdistrict #uk #derwent #peakdistrictlandscape #peakdistrictnationalpark #nature #landscape #hiking
The halfway point of the hike, having lunch with a gorgeous view of Derwent edge, Bamford edge, Derwent/Ladybower reservoir, Lose Hill, and in the distance Mam Tor and Kinder Scout (out of view right) #peakdistrictnationalpark #peakdistrict #nature #hiking #landscape

After years of reading that #TimeMachine backups couldn't be rsync'd and whatnot because hardlinks and more complicated directory hard links.

Something must have changed or the information I was reading was all wrong for networked TimeMachine backups. I believe hard links are heavily used in HFS+ and the newer APFS volumes. However for storing these on a networked share or none Apple filesystem they are placed in a "sparsebundle" which is disk image, on the underlying filesystem is stored as some metadata files and a number of "bands".

With that and TM being finicky at times, I finally decided to try moving my backups to NVMe from spinning rust. And it all worked!

I think it was: https://blog.fosketts.net/2015/07/22/how-to-use-mac-os-x-sparse-bundle-disk-images/ which gave me the right info for how "sparse bundles" work and can safely be rsyncd.

Also a special shout out for https://eclecticlight.co/ the depth of knowledge and the T2M2 utility for analysing TM Logs.

My new storage box is now faster and much quieter (no longer need to restrict backups to not run after 11pm).

Next changes:
- Upgrade networking to 2.5Gbe
- Set up `sanoid` and `syncoid` for zfs snapshots and send them to the spinning rust.

Shiny (and dusty) green motherboard for attention :P

Great justification for spamming me.
I also receive calls trying to sell me a phone plan because “I’m a mobile network user”, which is equally ridiculous justification.
Should I be getting spam from vape shops because “I’m a lung owner” next?

A $199 jump rope with a $12 monthly subscription. The world is doomed. I'm calling it.

Is Crossrope’s smart jump rope worth $200?

I spent a month testing the $200 Crossrope AMP Jump Rope Set. There’s a lot to like, but it’s hard to recommend for casual users.
