Time Machine Backup from a bootable drive
I have an issue with my mac book pro. I'm getting the prohibited sign.
I tried holding option and loading up my Bootable Flash drive and my time machine drive, but it still gave me the prohibited sign.
Eventually, I was able to used a bootable flash drive of the Os. Although it did have to wait 10 minutes as it flickered between the Apple logo and prohibited sign.
When I am in the macOs utilities, I have access to a few tools like the Terminal, I even used it to copy a few files. Which means the hard drive seems to be fine, but it may be the logic board or something.
Anyway, I want to copy all the stuff off of the drive so that I can restore using the backup drive. The time machine section in macOs utilities is only for restoring but not transferring.
Is there a way to mimic a time machine back up in the terminal?
As I said earlier this hard drive is showing up in disks utility and all of my files are still there. I wanted to try a system restore to see of that fixes it. My previous back up is at least 90% the same as my system now, so I can possibly afford to forgo backing up the drive in the current state but I prefer not to.
2nd Question:
Whether I am able to backup my drive or not, if restoring it doesn't change anything what should I do?
