I had a similar photo which I've lost. This time I need to publish it as soon as possible and if something goes wrong with my hard-drives then I still have a copy somewhere on the internet. From my past lost, nowadays I am publishing all my photos that is worthy of publishing. No need to hide in the hard-drives and hard-drives corrupt unfortunately.
For me publishing up on the net to photo sharing site or social media act as a cloud storage. I am not doing this as a profession so there's no need for cloud storage. But I must be very careful with my photos. At least backup twice your photos. If I have an important I double and even triple my back-up before I can go to sleep.
It was painful to lose all your shots in one year, but I know I can re-shoot it again. If I travel outside Australia. I am definitely going to double backup and never delete my cards until I'm sure that I have secure my memories in multiple places.
For this shot here, I am surprise that not many photographers have taken this shot. I am seem to be the only one interested in this section of the harbour. I know the Harbour Bridge and Opera House just opposite this that's the reason. But as a photographer you want to take as many shots as you can. It not the thousand of similar shots of the Harbour Bridge and Opera House that every tourists want to get. Come on there's more to Sydney than those two icons.
