Merge .tar with CMD

Hello all,

My server backups are automatically send to Onedrive, but the Onedrive API splits the .tar files.
So I need to merge the files, before I can open them on my PC.

The backups have a different names each day, so it's a pain in the ass to always look for the file names, and then merge.

Is there a CMD command that can do that automatically ?

This is the command:
copy /B/Y backup_1909051552.tar + backup_1909051552.tar1 D:\Onedrive\serverbackup.tar

I would like CMD to auto find the name of the .tar files "backup_1909051552".
Something like:
copy /B/Y §.tar + §.tar1 D:\Onedrive\serverbackup.tar

I hope you understand what I'm asking, and if this is possible?

I think it is possible to create a batch file that does the job but I wonder why you are not using the date on the destination file: Serverbackup.tar. Are you aware that the file would be overwriten whenever there is a new backup?

Yes, but it was just a test.
I found out how to do it. Just need to set the correct filename

Code:

cd Onedrive\Apps\plesk-backup\supportforum.be\backup_1909080119.tar_
copy /B/Y *.tar + *.tar* D:\Onedrive\serverbackup.tar
