Well it was duplicati, until it pulled this bullshit on me. I had a critical local failure of my data a month ago, 2.8TB lost. Pulled the backup off AWS S3 with my linux server, asked Duplicati to restore it, and it’s failed 4 times for random reasons, taking a week to get there each time. Once I can get this backup to finally restore, I’m moving over to Duplicity.
Exactly where my failure is. It’s corrupting mid-way through the rebuild for no apparent reason.
