Hi
I'm heading to the Galapagos later this year and looking for some advice so I can figure out what to take in the way of memory cards and backup:
On average how many photos have you found you take a day there? I know that will depend day to day on how much travelling vs wildlife...
How did you back up- was looking at tablet with external hard drive, which is the main advice I've found on the internet, but wondering if just backing up onto micro SD cards in the tablet is a viable option?
Thanks

How did you back up- was looking at tablet with external hard drive.
I use a thumb drive which holds 32 Gigabytes - about 10 years worth of photos (and counting!) in my case! When you mention an external hard drive I think of something bigger, in physical size AND storage size, than a thumb drive or USB drive, as they are also called. A 32 GB USB drive costs as much as a couple sandwiches, so they are quite cheap, all things considered. Not sure if tablets have USB ports, though?.... Of course, the bigger external HDs have up to TB (or more?) of storage, which is huge. External HDs are quite cheap as well - they are just a bit bigger and heavier than a "thumb drive".
I back up photos even 1 step further using Google Photos. The storage space you are allowed is unlimited if you choose to save your photos in original quality instead of super extra ultra extreme quality, or something like that.

I don't see why using an SD card would NOT be a viable option, though. Just back up your back ups, too. Put those photos in a cloud-based storage like Google Photos.
Firms such as Sandisk make "dual" usb thumb drives. So a regular usb port and a micro usb for connecting to tablets or cameras.
Sounds like what you need. A quick look on Amazon shows a 32gb for £8.03 so not expensive.
Any option that gives you plenty of memory should be fine, what matters is that you take something! You will take at least twice as many photos as you think you will 
Backing up to Google Photos as well may be a good idea in theory, but in practice if you're on a cruise around the islands (as opposed to a land-based trip) you won't have wifi so it wouldn't be possible. So I would be tempted to use a 'belt and braces' approach, saving to a memory card and to a hard drive / thumb drive.
Also important from a photography perspective is that you have spare batteries. You should be able to charge them on even the more basic boats (but double-check before going) but even so you don't want to be face to face with a marine iguana or albatross or booby or ... and not be able to take any photos because your battery has gone! Take a splash-proof bag for your camera for wet landings, just in case. And consider taking a camera that can be used underwater for when you're snorkelling.

I have been told that my Google+ photos would go away last month. And they appear to be still there, but I can't change the titles, I can organize the albums in any order, and the photos are no longer jpeg files. If I go in to Google photo albums, the photos are jpeg files, but I still can't organize the albums

Google+ is something different, I believe - I think that is (or was?) a social platform? It is being or has been more or less phased out at this stage.
I believe (and hope!) Google Photos will remain.
I uploaded my photos from Picasa to Google. Initially it was not Google+ but I was led to believe that I needed to move to Google+ to have extra storage, which I paid for. I didn't use it as a social platform at all and disabled face recognition. I wanted it as an archive. The photos seem to still be there on Google photos, but I can't work with them.
Not too familiar with the Google+, but uploading your photos - in original quality - to Google Photos is unlimited as far as byte storage.
We just keep 'em there for safe keeping and do not work with them. Once in a while we pull one from there to put onto our website.
I don't edit the photos on-line, but I did want to change the titles of the albums and put the albums in order by title. It would make the albums easier to find.
Google + closed beg April. It was a social media used for publishing comments, articles, photos, videos.
Google photo remains. It 's the place you can store your photos with no limitation as far your pictures do not exceed 16 Mbytes. Very useful to backup photos in the cloud
