PBS sync job to local usb drive failed

[SebastianHenn]

Hi,
I used this post to create a local sync to an external USB Drive: https://forum.proxmox.com/threads/external-pbs-copy.78215/.
Everything worked fine, until I started the sync job. I always get this error:

2023-01-21T09:35:44+01:00: Starting datastore sync job 'localhost:BACKUP:USB::s-f7628ce3-dc2f'

Hi, it looks like PBS cannot create directories on your USB drive. Can you check whether the backup user has write access to /path/to/your/mounted/usb/ns and its subdirectories?

Solved: I tried formatting it again and now everything just works fine.
