Once a month, I copy all the files (including Ondrive) to hard drives that I rotate at work, and one in the car. The hard disks are locked with Bitlocker. My most important files are packed every few months and uploaded to onedrive with a password. I know very well that onedrive is not a real backup … but it's part of my recovery plan.
Twice a year (sometimes more, sometimes less) I do a backup drive 500 km away from my parents' home. I have been doing this since the late 90's. Usually, old drives get this job.
Seems a lot, but is mostly automated. I need to connect the hard drive to my computer for backup, but that's fine.
I also have a "backup" laptop with copies of my desktop computer … it's an old Lenvo. I need to turn on the laptop so that it can be synced … I use Goodsync to maintain the backup. I also use wareync to backup my main laptop, which looks like a backup, but it is always active.
FileHistory and Storage spaces is a lifesaver, but I only needed it once to get a file from a previous year. It was cool that it worked and the file was sitting there. If I could not get the file, not a big loss … not a big guy at all. It was nice.
I was trying to use a NAS, but that did not work … I could not move my current backups to it. Damn thing locked up and in the end I sent it away. Plus, it was something else to create, which I did not want (I know it's not that much work, but the short time I had had some problems to solve).
It all changes … if I'm developing or creating something important, I'll make backups more often and possibly use Myspaceync to automatically load backup work onto multiple cloud platforms.
Point is, if everything goes up in the house, I have backups in different places. Never know when flooding or whatever your house will wipe out.
