- "If you had flood damage or worse - your house burnt down - you pictures, files and music would be far from your mind to start with but eventually you might want them back. But in those scenarios your 2nd internal drive and NAS has just been wiped out, so you've lost everything. Thus my original statement of if you haven't got an offsite backup you haven't got a backup still stands. Local backups are just there for when the internet is down and you need to get them."
Right at the moment I don't have off-site backup. I'm in the process of moving to reside across the street from our youngest son. He and I will be swapping off-site backups for my data and his business records. This reminds me of back in the early 70's when I was responsible for a 24-hour shop, we did backups while folks were on lunch break because processing was heavier overnight, and I carried five or six reels of magnetic tapes home every night, all data, source code, and OS . The company was not very concerned with backups, but I did it anyway. Later on we swapped storage with a nearby business. Usually kept six days of them plus archived month-end copies also.
Now with Windows and laptops/desktops, I normally make multiple verified copies of everything before, including all software installs in one place so I can rebuild easily. Sometimes this is simply to a shared drive on another machine, but it is always conveniently available so I don't have to go looking through storage for installs and risk getting the wrong versions
With my personal financial data, which includes 33 years worth of backups, I have archived copies from before and immediately after each new version, This always includes copies of data files which get modified during the upgrade, so it can be rerun if needed.
Maybe I suffer OCD? But I don't believe I've lost any data in decades. Even back in the days of my 24-hour shop when folks were doing manual data entry from 400-500 hand-written product orders daily, we always kept the hard-copy orders for a month before destroying them.
