Hello Eric
I go on the 6th November. I am only doing the Australia tour. I went to Singapore, New Zealand and Hong Kong before my wife died and it is very rare for me to go to a place twice.
In the past I have not backed up my photos. But on one of my holidays last year someone had their camera stolen in the street and she lost her photos. I will be taking a small tablet pc with me (Nexus 7) and I have recently bought an “Eye-Fi” SD card. This has Wi-Fi built in to the memory card. This card will automatically copy all my photos to my tablet pc (or my smartphone). The software supplied with the card will then automatically copy them to my chosen place on the internet (I use Picasa). I hope it is as good in practice as it sounds in theory.
You may be able to take your memory card into photo shops and have them copied to disk.
When I return from my holidays I also like to share or swap photos with other people on the trip. I do this by uploading them to Picasa and sending a link by email or occasionally I send people disks. I think it is interesting to see how different people tend to concentrate on different aspects of the holiday.
