And keep the backups up to date.
I'm a computer guy, software developer for a living for the past 20+ years. I'm the one who set up my companies SQL server backups with multiple levels of backup.
But tonight in my personal machine, my main 2TB hard drive crashed. Hadn't done a backup in about a year. Backup didn't include several files which I now realize were very important to me.
I've been lucky in the past that any drive failures I've had were the slow kind, where the drive starts to have read errors and they gradually get worse. So there is time to transfer the important stuff off to a replacement drive.
This time it was instant. Machine was running along fine, went to some website in my browser and it looked like it timed out. Then I realized the machine itself seemed to be sluggish, then blue-screen of death. Now the drive just makes a clicking sound when it first spins up. After 30 sec, it gives up, and spins back down. It's toast. And the stuff I lost isn't worth the price of a data recovery service, so I'm just re-building from scratch and recovering the parts I did back up last year.
I'm so pissed at myself.
