WARNING EC1329: Unable to create local agent backing store direction '[path]': [OS error message]
When using agents on the same host as eMake itself to execute a build, eMake directly copies file data to the agent’s temporary storage instead of transferring the data over the network. This warning indicates that a eMake encountered a problem while attempting to copy file data.
Because the error involves an external system in this context (the filesystem on the eMake host), the list of possible causes for this error is virtually limitless: a corrupted filesystem; hardware failure; insufficient permissions; and so on. Refer to the specific OS error message to determine the cause of the failure.
