Hey,

where is the datastore saved(local folder, NFS, ...)? It looks like you don't have permission to write there(wherever that is).

It's iscsi device manual mount as a local foler, then use web ui to make a datastore with that folder.
And I can backup ct no any problem.
Yes, I change the permission of mounted folder, then backup can successful create vm folder at the mounted folder.
The vm backup can run smoothly.
Thanks for your help.
