To back up all my stuff I use dropbox.com. It's great. You get your personal folder, and you can access this folder anywhere. The folder is technically located on their server so anything you have in it don't take any space on your memory. You can put this folder anywhere, kind of like a shared folder on a network. The folder is the same whereever you access it from. ie. I have this folder on my laptop, on my PC at home, iphone and I can access it online so I can access it from internet cafe or when I stay with locals. I used to have the free 2GB and use it for my important document when I was traveling - copy of passport, driver license etc and whatnot, but I found it so convenient that I know use it everyday even when I am not traveling using their 50GB account for $9 a month where I put all my music and pictures so they are backed up on their server and they don't take space on my iphone or laptop. It's great because I can access them all the time. When I travel, I go online and dump all my pictures in this folder so free some space on my SD card.
I recommend to put your camera in your handlebar bag so you can access it quickly. I used to put the camera between my clothing in one of my pannier but I found out that I was not really using it as it was cumbersome to take it out all the time. I use the Ortlieb camera insert for handlbar bag: http://www.cyclocamping.com/Accessories/ortlieb_camera_insert_for_ultimate_handlebar_bag_m_or_l/GOTF94-50.aspx
. It is nice I put my SLR Canon camera, 2 lenses (wide angle and 50mm), SD cards, my Iphone and a few gadgets. I do use a tripod and I would never travel without one. they are perfect to take picture of yourself on your bike or to take picture in low light condition (evening by the tent, inside of a home etc.). The best kind I found is the travel tripod that can expand up to 40-45 inches. Like the Tragus 8 section. They are inexpensive, very lightweight and compact enough to fit in my handlebar with the rest of my junk. They are not very strong and I do have to buy a new one every couple years but they are strong enough for my heavy SLR even when there is some wind and tripod stronger than that are way more too heavy and won't fit my handlebar.
