This week at work we have been working on a video to promote backing up data. The tagline is “what’s your backup plan?” – which has made me think about how I back up my data, and how well what I actually do measures up to what we recommend.
The basic message is that for a file to be backed up, it needs to exist in an identical version in more than one location (and ideally three locations, one of which is physically separate from the actual machine the data is created on). I do try and adhere to this, although I think I’m still a step away from being as safe as I’d like.
I have two basic backup strategies. One is to ensure that any file I edit exists in some sort of cloud storage system (usually Dropbox, iCloud or Evernote). The other is to ensure that any computer I create data on is backed up regularly using at least two different methods/products. The combination of these two systems, plus the fact I use quite a few computers, ensures I always have several copies of everything, and can access historical copies of my data and bootable clones of my whole computer in almost all scenarios.
Most of this is now automated, in that all my machines back up locally through Time Machine on an hourly basis, and once a day to a bootable clone created using Carbon Copy Cloner. This works fine providing my house doesn’t burn down. I also back up my main home and work computers once a week to a disk that I keep with my at all times, but this has to be done manually, which isn’t ideal.
My iOS devices back up to iCloud, but also back up to my computer every time they are plugged in (with the backups then being themselves backed up as part of my other backups). I don’t have any unique data on them (at least not for long), but I still think it’s worth being able to restore them quickly and to have a second (and sometimes third) copy of all my apps.
So that’s my backup plan. It’s not perfect, but it covers most of the bases.
