Environment

VCF 9.1

Cause

This issue occurs when the backup user account configured on the remote SFTP server lacks sufficient file system permissions for the designated backup path

Resolution

Log into the SFTP server and verify that the backup service account has full read, write, download, upload and execute permissions on the target directory and its parent directories with correct ownership.
