I was thinking of using a simple backup strategy like copying my Documents directory into the Dropbox directory.
This strategy should work in case my laptop gets stolen or my house burns down. But if the data gets corrupted on the part of the cloud storage provider, the corrupted data will be synchronized with my local directory and I will lose the data from both locations.
More likely I can accidentally corrupt the local data and it will be synchronized with the remote version and destroy the data on both locations.
Is my reasoning correct? If so, does the following strategy make sense?
In addition to backing up to Dropbox, I would back up to a local directory using for example Deja Dup. This way the data is protected against both destruction and corruption of the data.
