UNPAID

Long story short, I wanted to copy a folder that was just over 3TB to my Unraid server and I used robocopy to copy it over. I watched it for a little bit and left it to copy as it was all going fine. But when I returned some time later, I found that it only copied just under 500GB. Trying to copy anything else to that share now showed that there was "not enough space". I have an array of 3 usable disks with around 14TB of free space and a 500GB cache SSD. So it seems the cache got filled up possible? But why does it not write directly to the array instead? Should I just disable the cache drive completely if moving such large files at once? The mover is now active and moving all these partial files over to the array but all those files will have to be copied over again... My shares are setup as per some videos I saw. I did some copying in the past and it was okay but it wasn't so much data at once.

This is way over my head but I think I understand. I only ever use /COPYALL for flags but I tried /copy:DAT and I got 0 errors and no fails! And of course, "S=Security=NTFS ACLs". Thank you for your help. Even though it wasn't stopping it from copying it's good to know what was causing this error.

I got a large local disk on my Windows 10 that I wanna back up to my Unraid Server. I love using robocopy as it gives me less hassle than using explorer when copying large amounts of data and avoiding the character limits. So I wanted to use robocopy to do the same over Network. Initially I was denied access, the usual but after messing around and making the Share Public, it allows the test file to copy over. But I'm still getting this error: ERROR 1314 (0x00000522) Copying NTFS Security to Destination File X:\TEST\TEST.txt A required privilege is not held by the client. While the test file copies over okay I wanna make sure this won't cause me issues once I start copying TBs of data and if there is something I'm missing. Is this error got something to do with the XFS FS? I'm still new to Unraid, I set it up almost a year ago but not really used it until recently but I love how easy it is to work it using the web interface.
