The article makes a very good point. I already am paranoid about what data I make available online, and I will NEVER use cloud storage for anything, PERIOD.
Here's a thought right off the top. I already keep all my information and application data in a single directory simply called 'c:\DATA\ under which each application is given it's own directory for it's data files. I learned this from an old VP of IT that I worked for long ago. Now I'm the old guy, and I still use his method. I can quickly back up all my data without copying all the installed software and such. Lots easier to rebuild a system and reinstall software than to recover data. I also keep a directory called 'c:\INSTALLS\' where I keep subdirectories with most of the install packages for the applications I use regularly. This gets backed up regularly also. This way, I can reinstall an application as needed and recover its data quickly as I need them in case of a total wipeout. Also, keep a list of the keys required for re-installation somewhere that will get backed up too. For this I use Microsoft OneNote, with it's files and backups also in the c:\Data directory.
Here's what you could do for travel:
Back up your c:\data\ directory to a USB drive, remove the directory from your PC, and from the recycle bin, and if necessary, even ship the USB drive to yourself at your destination, so it arrives separately at your destination. Then also carry another USB drive with you but in separate location from your PC.
1. Always, in any case, be sure you have two backups on different devices so if one dies, you have another copy even if not totally up to date. Always have some kind of fall-back. Don't trust ANY hardware as your only backup.
2. Especially if you keep things like backups of your financial data history in annual files, be sure these ALL get upgraded to the current software version. Then burn them to DVD storage. Don't put it off until you need it.
3. Test your restores regularly to be confident that they are up to date and will work correctly.
Forty-two years of working in IT taught me a few things that I still practice in retirement with my own data. Even in the old days of backups to the reel-to-reel magnetic tape, we always had two people take copies home with them for off-premises safety. Maybe you have a family member close by with whom you can trade off-premises backup storage, just in case you have a home disaster. Set up a shared drive on an old desktop at their house and copy your backups over during the night. Or trade USB drive backups when you visit them. Or at least hide a USB drive in your vehicle so it is out of your home. You can back up lots of data - from your DATA directory - on a 1TB or 2TB usb drive.
I've even known guys who maintain a PO box to which they ship backups for off-premises safety.
My laptop is an Asus ROG machine which has the excellent design feature of a second internal hard disk that serves as a convenient self-contained backup location but on a separate hardware device. Unlikely that two hard drives would fail at the same time.
Data security can be simple with multiple possibilities if you just USE them.
Disaster Recovery = Backup ( Backup ( Your Backup ) )
