External hard drive with automatic backup?

Hello everyone,

I apologize first if this is in the wrong section. My work involves writing/composing a lot of letters/documents, and I'm looking for an external hard drive to backup all of my documents that can do the following:

Say I have the hard drive already. I have all of my documents on my laptop and a copy of each of them in the hard drive. When I finished writing a new document and plug in the external hard drive, the hard drive will automatically detect that I have a new document and will make a copy of that document in the external. The hard drive will also automatically copy and replace any new version of the existed older documents.

Is there something that can do what I described? I hope the situation makes sense as I'm terrible with technology.

Thank you

 

There is plenty of synchronizing software that can do that... You don't need to look for a harddrive that comes with one.

You just need to try out different programs to find out which one works best for you...

I have tried a few, don't remember the names of those I didn't really like, but I am currently using "SyncBack". Is is small and relatively simple. I didn't want a heavy utility running all the time. I use it to sync on demand - have created 2 profiles to sync, each with specific settings (direction, whether ot overwrite and so on) and just run it every now and then and it works quite good.
Again it is nothing really powerful, does even look a bit old-style, but does exactly what I need it to do without messing around and taking up resources.

But again - look for sync. software and try out a few to see which one would do what you need it to

 

Thanks for the suggestion. I will look into it
