I'm trying to use a Storevault S500 as a storage location for Zmanda's ZRM for MySQL backups. I have exported a directory in /vol/exports as an nfs share, and have mounted the share on my backup server (running Ubuntu). Both the 'mysql' user and the 'root' user must access this share at times during the backup process. The 'mysql' user creates a new directory for a backup, but then runs a command in that directory with sudo. The command fails because, for some reason, the 'root' user does not have access to the directory 'mysql' created! I tried the options for security in the Manage Exports dialogue to attempt to give all users from that host access as 'root', but that did not help matters. Can anyone offer advice? Where am I going wrong?
