I routinely do backups on external hard drives using
backintime. It is a tool which uses
hard links to create snapshots with deduplication. Restoring is super easy,
either use the tool or copy files manually. The directory hierarchy had a
directory with time as filename and your whole directory tree below that.
As I only do these backups every couple of weeks, there is a gap of time during
which I could lose data. Also on the go I want to have backups. My PhD thesis
draft is in a private GitHub repository, so I can just push to that and have a
backup in the Microsoft cloud somewhere. For everything else I need something
else, so I started researching this a couple years ago.
Backblaze offers a software client and unlimited
cloud space for 5 USD/month, but just for Windows and macOS.
The SpiderOak service was recommended by Edward
Snowden, so I tried that. It works with Linux and has encryption already on my
laptop. I just needed around 150 GB of space, they used to charge 10 USD/month
for that tier. Their client looks nice to use and I quickly had set it up with
the free trial. It took a while before it actually started to upload things.
And it seemed to use quite a bit of resources, I guess for encryption and file
My friend Simon, who had the same problem, discovered that one could also use
duplicity with the Backblaze
B2 storage backend. Their
rates are really affordable and so I had a look at that. One can store
unlimited data there and is billed proportional to the amount. I ended up
paying a few EUR/month for the service, so it was cheaper than SpiderOak.
I want to show how I did it with duplicity and why I am now back with
