Just want to chime in that I get the same error. With 2025.2.0b1 I could not connect to OneDrive. With b2 it is possible to link it.

Upload failed for onedrive.ea093e654287a17c: Backup operation failed

Hmm, just checked my OneDrive and the Folders /Apps/Home Assistant/backups_slug/ are created and I even see a .tar file in the folder.

The state inside Home Assistant still says the upload failed though.

Tried an encrypted and unencrypted OneDrive backup. Both give the same error, and both upload the file just fine.

Just tried the same thing again; Initiated an automated backup and the upload to One Drive succeeded.
Appears to be an intermittent problem
