One of my co-workers has been getting recurring crashes when in the office. It wasn't happening when she was at home or when she took the MacBook into the Apple Genius Bar. Here is the first line of a typical crash report:
panic: "hfs_UNswap_BTNode: invalid backward link (0x0000250b == 0x0000250b)
HFS means it has something to do with the file system. Kind of sad that in this day and age, corrupt data in a file can bring down the whole system. But I digress…
I did a bit of sleuthing and aside from the typical "reset the SMC" and "clear the PR", there were reports that turning off Time Machine fixed it. So that's what I tried, and lo and behold it worked!
The promise of Time Machine is wearing very thin for me these days. I'm moving over to using Resilio Sync for our org's backups. It works cross-platform, and since it's based on BitTorrent technology, I trust it to be a lot more resilient to network and file system problems. And the nice thing is, it's super easy to have both an on-site backup and an offsite one.
