Another simple tip to make sure you don't lose stuff. Get yourself a Office 365 subscription which not only gives you the latest version of Office at all times but 1TB of OneDrive space. Configure your documents, pictures, music etc... system folders to be located inside your local one drive folder. The benefit of the above is that you don't have to think about backing up or worry about hard drive failure. With a couple of minutes of you saving to the HDD it then goes up into your OneDrive in the MS cloud. When you get a new machine you configure the above system folders to be in your local onedrive folder and you instantly have access to all your files.
Well, I like my independence too much to go the subscription route. I never use internet data storage for anything. Never use subscription service. I'm running Office 2010, and it works well, SQL: Server 2012 for my personal databases, and have no problems that I can't handle. I have not used any technical support for maybe a decade. Do it all myself, with the help and advice such as the folks on this forum. I believe my wife and I have about seven active machines on various versions, XP through Win 10, and all is good. I can upgrade if and when I want to. No pressure.
Whatever works for you, it's just a tip. The question is what happens when your HDD fails or your machine is lost to flood damage, or a pet knocks a drink over the tower/laptop - all the docs, pictures etc.. gone. If you don't have an offsite backup you haven't got a backup is the general rule. So really the question is how much are your memories and time worth?
SQL Server is not part of office 365 and is free for non-commerical use (ala developer edition) so not sure what bearing that has on what I said.
If you have 7 machines do they all have Office 2010 on them? If so that was quite the expense. With a family sub you can install Office for 6 people with each allowed to install it on a desktop, laptop, tablet and phone simultenously. Each person has 1TB each.
I was all against a subscription for things like Office, but the convience, backup and being able to have the latest features at a negligable cost compared to buying it outright make it worth it to me. I'm getting almost 4 years of subscription + 1TB backup for the price you'd pay for Office Professional edition.
If you ever upgraded to Office 2016 (or 2019 soon I think) then that works out to almost 9 years of subscription for the price you'd have paid for those 2 liceneses (assuming professional edition). I share the sub cost with my husband 50-50 so at that point for what I'm paying it effectively doubles to 18 years of subscription for the same price you'd have paid for 2 versions of Office (your current 2010 plus any version you subsequently upgrade to).
I'll be 42 this year so it may be an age thing. I'm on that cusp where I don't like the idea of subs but if the price is right for what I'm getting I'll buy into it. Another example, we eventually got Netflix about 1 or 2 years ago and it is totally worth the money, we watch vastly more content on that then on terrestrial TV or Sky TV (which we also have) now.
