So, after some trial and error, this command is working...
robocopy C:\ E:\system backup /s /e /v /r:1 /w:5
The r:1 means it only retries one time when the file cannot he accessed. W:5 means it retried every 5 seconds. This helped stop the problem of infinite retires. Xcopy kept running into the sufficient memory problem. The only downside with this current command and transfer is that it's taking forever. It's still going. Its on hour 31. Is that normal or is there something that could be causing it to take forever?
Ok, so I let it finish up the process of copying everything over. Only, it said that in the end it there wasnt enought disk space, even though I know there was plenty initially. It literally spent more than a day just copying C:\DocumentsandSettings\Cjepp\localappdata\.... I let it go just to see how long it would take in total. Nearly 70 hours!!! Needless to say I will never be copying the entire drive again. I'll be more selective. The only problem now is that my external which initially 2 TB of free space, now only has 7 MB remaining. What the heck! How is that possible. The C drive I copied over only was around 200 GB! I deleted the systembackup file so I could start over and be more selective, yet it only cleared 23 MB of space! I am so confused. Please help meI never copied entry system so can't tell, there is no benefit to copy entry system, usually you just want to copy your personal data.
To find your personal data, you use following commands:
1. To navigate to C partition
2. To list directories in current location
3. To go forward into some directory
cd "some directory"
4. To go back one directory
You then copy the paths you want to your folder on external disk.
