Nucleus tool (dump_backup and upload) to migrate data from Server A to Server B

Omniverse Core Platform Nucleus
1

I tried using the Nucleus tool (dump_backup and upload) to migrate data from Server A to Server B.
However, it didn’t go well. Do you have any advice?

Below are screenshots of the original Nucleus interface and the interface after the upload.
Originally, there was a file named TEST001.usd, but after the upload, the files appear as TEST001.usd_@3 and TEST001.usd_@tot.

Thank you for your reply.
This is the result of performing the ‘backup/restore’ procedure.

dump_backup is : Running the Backup

In the log during the execution of dump_backup, the following was found.

[0] [MKDIR] /out/tree/default/Projects
[0] [M_OUT] /out/tree/default/Projects/dir.meta ＜＜＜＜＜
[0] [D] default // /Projects/NEW1/
[0] [MKDIR] /out/tree/default/Projects/NEW1
[0] [M_OUT] /out/tree/default/Projects/NEW1/dir.meta ＜＜＜＜＜＜

I think the log entry [M_OUT] indicates an attempt to create a folder or file.
However, the folder or file named __dir.meta__ was not created. There are also no error messages.
I suspect that the cause is that the __dir.meta__ file or folder was not created.

Are there any advices ?
Nuleus tool is “nvcr.io/nvidia/omniverse/nucleus-tools:1.2.2”

We would need a complete output log to understand what’s going on here.

Also, can you redownload your backup and validate your __dir.meta__ files are in there, and also make sure they exist in there.

If you have an enterprise license, can you reach out to your rep and we can help you more directly.
