Give this free program a shot bud, it works well for me.

Been a while, but can you set them up in raid1? I think that parrots across both drives. Not sure what the tax on performance is.

I’ll check that out tonight. Thanks.
I think that’s only good for drives that don’t have data on them already. And, raid scares me, I don’t want it. Just one main drive, and one for backup of the first.

Ahh. I re-read your original question and I think I misunderstood. Thought you wanted drive a=drive b for backup. and I guess you do, but one drive is larger than the other and has more data on it? so can’t use raid1 anyway.
That software @DougDawson posted might be the ticket then if you can view everything at the file explorer level.

i wrote a script called de-dupe, well larry wrote it, and it’s on github. it goes through the folder path you enter and checks that folder and all the ones under it recursively for duplicate files then it lists them and their md5 hashes. you could use that to get a list of the duplicates and then delete the ones you don’t need. just copy it to the root of c and run it from there. it may take a while so i’d leave it overnight. it’s in python.

This works in powershell, super easy, just update the drive letters to be the actual assigned drive letters for the drives in question. Powershell is native to windows and requires no installation of extra software.

Macbook Pro SD Card Reader Slot Not Working (read only mode, won’t recognize drive, can’t format/erase, can’t wire to it / move files to it, etc.)
If you’re having this issue, and you look up fixes, you might find software based fixes, or something to do with the “lock”/“unlock” tab on the micro sd to sd card adapter that comes with many micro sd cards. If that doesn’t work, try this:
I turned of the MBP, then I did this procedure three times. The first paper towel came out looking pretty dirty/discolored along where the contacts would’ve touched it.
I powered up the MBP after and the permission status (in “Get Info”) changed from “read only” to “you have custom access” (or something to that effect), and it now allows me to move a file to it, etc. (have write access).
Alcohol would’ve been my next attempt - but I would’ve just sprayed some in there, tilted to laptop and let any excess run out, then let it dry.
This was a slick trick, considering I don’t think I have a brush or tool that would’ve fit.
So I had to share it.
I’m back on this data backup search.
I’m wondering what software you guys use. I’m talking more of “files and folders” backup (I think that’s what people call it) as opposed to “system image” backup. I don’t tend to make/save files and folders on my main/system internal drive. I save these things to an external drive.
So, I have two large external drives now (with external drive enclosures). One of them, drive ‘A’ I guess. I’ve consolidated pretty much all the “files and folders” I have on to it. This is also the drive I “use”, both to save new stuff to, and also to - for example - access files from (if I want to watch a video, or something like that).
I want my second large external drive, drive ‘B’, to be an exact copy of drive ‘A’. It’s easy enough to manually “copy and paste” everything from drive A over to drive B, But I want some software that will monitor drive A and drive B, and update any and all changes made to files/folders on drive A to drive B - so that they remain identical. So that, if I change the name of a file or folder, or I move or delete a file or folder on drive A, the software will recognize that change and update drive B to reflect that change and keep them both the same.
Did I explain that clearly? And does this exist? I know I tried to explain this before.
I’m wondering if software like “Fbackup” can do stuff like this.
(Note: I also would like to have both drives encrypted, or at least “parts” of them if possible. But I don’t know yet if that should be done using whatever backup software - as some say they can encrypt backups, OR if I can use veracrypt or something like that to do the encryption [an encrypted container] - or if that would make the backup software not be able to function properly in backing up said encrypted data.
Please don’t think I know a lot about this, haha. It might sound like I know a little more than I actually do, which is only a little bit).
Edit: Is there a term/word for the type of backups where a software will monitor/recognize (just “recognize”, if the drive is not left connected all the time) changes made to the …source drive/location, and then make those same changes to the destination drive/locations to keep things the same?
–“Sync”, perhaps? (Aoemi seems to suggest that’s what this “feature” would be called). By the way, I don’t mind paying for software, but I don’t want to pay a recurring fee/subscription.
Thanks.
