Issues with my Mac mini and file backups

I had a bit of a scare with my Mac mini a couple of days ago. It was one reason why I didn't post anything in my blog for a bit. Yesterday, my Mac mini was still out of commission. I used my laptop to make my update.

The last time I used my Mac mini was the night before I went on vacation. When I came back, I uploaded all my photos to my computer and then shut it down.

The next day, my Mac mini would not boot up. You typically get a white progress bar and then your screen to sign in. I ended up with a black screen with four options to restore my computer. It wasn't a good sign.

I rebooted it a few times. I got something different each time, including a circle with a slash across it. My Mac mini was also trying to detect the power button and my wireless mouse, but was unsuccessful.

I decided to unplug my computer's power cable from the wall outlet, wait for roughly five minutes, plug it back in, and start my computer up. Guess what? My computer came back to life. Yay!

I did some research online. This incident happens when an automatic software update starts, but doesn't install completely. It must have happened while I was uploading my photos, but I had no indication that an update had happened. Powering off my computer cleared this installation process up and allowed my computer to boot up properly.

The last time this computer died on me occurred when I was upgrading the operating system. I went to the Genius Bar at my local Apple store. For some reason, genius sounds sarcastic in my head. The solution was to reinstall the operating system, which meant that whatever files weren't backed up would be lost.

I was bright back then to have the majority of my important files, the bulk of which are my photos and music, on my external hard drive. Wiping my entire hard drive was fine. I restored them just fine.

However, after restoring my Mac mini, my music remained on my external hard drive, but my photos had to be on my computer's hard drive to sync properly with my iPhone.

This recent scare made me decide to do the following:

• Move my Photos library back to my external hard drive. I don't own an iPhone anymore, so I don't have the need to store this library on my hard drive.
• Back up my Mac mim's hard drive. 

The second point is significant. I don't know why I never got around to backing up my data. The photos that I take on my Google Pixel phone are automatically backed up to Google Photos, so I"m good there. My photos taken with my DSLR camera are not backed up. Should I lose them on my hard drive, I have nothing.

Right now, I am in the process of moving my photos from my hard drive to my external hard drive. I have 170 GB of photos. It will take a while!

I also have Time Machine set up to back up my files at long last. Better late than never, as the saying goes.
