Copy only modified files

Solved

Good evening everyone,

As a graphic designer, I have several hundred gigabytes of professional data on my computer. To avoid losing anything, I back up to an external hard drive. To do this, I copy my main folder of 600 gigabytes from my computer and paste it onto my external hard drive. I regularly replace the previous folder. I let you imagine how long it takes...
But out of these 600 gigabytes, I only modify a few dozen files each day (never the same ones, of course). Therefore, I would like it so that when I perform the copy, I am offered to copy only the files that have been modified since the last copy. To save time.
Does Windows offer this possibility? Or do I need to download software? If so, which one?

Thank you in advance!
Have a good evening everyone.

You don't even need software
When you do your backup, sort your documents by last modified and only save those that have been modified previously.
Otherwise, you can use software like XXclone or Cobian Backup, but I don't know if there's a specific feature for your use.

Thank you for your response. This technique would still be too tedious. In my main folder, I have about a hundred folders organized by my clients' names. In each of these folders, I have a large number of folders organized by project, in each of these project folders, I have more folders organized by creation, and so on.
So if I organize the folders by date of modification at the first level, I will again have very large folders, even though I will have only modified a few files within each at some sub-levels, so it will take me a lot of time again.

However, I will take a look at the software you mentioned.

Otherwise, if you have money, you could do a raid on your computer so that the data is automatically backed up.
This involves having a mirror of your disk at all times without affecting your performance.
If you have a laptop, I think there are software solutions for that; I will look it up.

You can use SyncBack, which performs the operation you need.

I'm looking into SyncBack!

I quote:
"SyncBack is a backup tool that allows you to perform file or directory synchronizations (mirroring): instead of copying (stupidly) all the files with each backup, it simply adds the missing files and updates those that have been modified."

I want to say: Hallelujah!!!
It couldn't better describe what I was looking for, and I don't understand how I missed it despite all my searches.
A huge thank you for your response and especially for your speed; I will install this software tomorrow!

I really like the idea of the hard drive mirroring (but is it paid?). Because if I understand correctly, every time I'm in Photoshop, Word, or any other software, as soon as I save my file on my computer's hard drive (which is indeed a laptop), it would also automatically save on my external hard drive? (if I'm connected to it, of course). And if my computer crashes for any reason, the backup on the external hard drive still exists?
That would indeed be ideal! But I'm not sure I understand the concept of "raid," having little knowledge of pure and hard computing (and even less money :-) ).

Hello

RAID requires equipment and some knowledge on the subject.

The solution of a synchronization software seems to be far preferable.

You can try this one:

http://synkron.sourceforge.net/

I don't know it particularly well, but it should be suitable.

Make sure to run several tests on unimportant directories to fully understand how the software works and not to lose any data by mistake.
