Karen's Replicator Somehow Loses Space When Copying From One Drive To Another?

It's my first time using Karen's Replicator (KR).

• Windows 10
• Two external 4 TB drives
  • Source Drive
    • Formatted for Windows
    • has a little over 1TB in data
  • Destination Drive
    • Clean/formated in exFat (to transfer to Mac)

So I just want to copy the data to the exFat drive using KR. I use the command:



However even tho the source drive has just a little over on 1TB of data, KR ends up copying OVER 4TB of data, hence running out of room.

I have zero idea how that happened. If it weren't that much data, I could look through the folders to see what's going on. But I can't.

So if anyone has any experience in this area I would greatly appreciate any help figuring out what's wrong.
Thank you

 

It seems that there is a known issue with this software on Windows 10 that affects the permissions and causes it to copy more data than expected. One possible solution is to specify the IP address of the machine in the job, instead of using the drive letters. For example, if your source drive is D: and your destination drive is E:, and your machine’s IP address is 192.168.1.254, you can try using the following command:

\\192.168.1.254\d$\ -> \\192.168.1.254\e$\

This might help you avoid the permission problem and copy only the files that have changed or are new.

You can use robocopy, it is the easiest way to copy a lot of data fast.
Hit Win+R, in the run command type "cmd" and hit enter. When the console opens, type robocopy "source" "destination" /s /XD $RECYCLE.BIN "System Volume Information" /w:1 /r:1

 

robocopy and xcopy eventually fail. I forget which is which, but there have been out of memory errors, and I think failures on illegitimate file names (I'm guessing pathnames that were once legit or not sure), and whatever else I can't recall now.

One of my biggest gripes is that since I am copying over 3 million files, it can take a day or more for whatever copy method I chose to stop working.

 

IDK, I've never had robocopy do that, and I've copied terabytes at a time. The only weird error I've had was using Windows Explorer to copy and get the path name is too long.

 

All I know is this: My late father (back in Windows 95) started scanning all his family pix and using crazy names: John and Stacey ======= 1970 ++++ Park Beach

I'm just trying to back everything up now to my Mac. if there wasn't soooo much data I'd do something over wireless. But this is what I'm stuck with. And I can't recall what each copy method failed with, because it takes many days to fail, or not copy everything, etc. etc.

 

I was just offering an alternative, if I was faced with a copy solution that is not designed for my OS and overflows the drive versus one that might fail, I'd pick the latter.
If robocopy fails, and you rerun the command, it will skip files that have already copied. Seems like you were saying you have to start over from the beginning...
If you need a GUI

Also why is it taking "many days"? 4Tb on an external (USB3.x) drives takes hours, not days, in my experience. Are you not using USB 3? or maybe it is the program...

I'm not here to argue, I am not paid by MS (robocopy), I am here to try to help.

No worries, didn't think you were arguing.

Yes, takes a while, days to copy and eventually fail. That laptop is 10 years old, using two external 4TB SATA drives, so not sure where the bottle neck is.
Maybe I should find a way to do partial copies with the Archive flag....really not sure.

But I can tell the instance of Karen's I am running now (using the IP address of my machine as someone suggested) has already copied more on TB than exists on the source drive. So I guess this one will end with failure.

 

USB 3 is 15 years old, but that laptop could have been a slow adopter.. USB 3 ports are usually blue in the connector. I was copying 4TB to an 8TB drive yesterday while tying in the forum and it took a few hours. Going back to the original post to look for a different angle, now I'm confused, you mention 2-4Tb ext. drives, then say the source is a little over 1TB. How do the two 4TB play into this?

 

The source and destination drive are both external 4TB drives. The data I am trying to copy from one to the other is a little over 1TB. But I'm running into all these problems/
