My 15" late 2013 Retina MBP has a bootable 1TB SSD. I want to back it up to a 1.5TB HDD and then restore it to a (potentially) new bootable 1TB SSD at a later date.
Sorry if this has been asked already, but everything I could find was about SSD->HDD or vice-versa rather than the best approach for SSD->HDD->SSD.
All of my user data (minus applications) lives in the cloud, on Github, Dropbox, and Google Drive.
I'm experiencing kernel panics on my machine that may be hardware related, and if I send in my computer to be fixed, my SSD will probably be wiped or replaced, so I want to back it up. It took me 3 days to get Windows 8.1 booting in EFI mode alongside OS X, so I want to back up and restore everything, including my partition table, bootloader partitions, OS partitions, and recovery partition. What is the best way to do this?
I'm considering bitwise-cloning the SSD to the HDD with dd by booting a *nix variant from a USB stick, but I have a few concerns: - If the SSD gets replaced, it could have fewer bits than the old SSD due to error correction or manufacturing tolerances - I've read that copying an HDD to an SSD can cause alignment issues with a substantial performance impact
I'm not afraid of the CLI, but I also don't know much about partition tables, hardware, and low-level system tools, so I need some advice.
