I'm using the backup option "Backup all files in web directory as root user", where all files are now .tar.gz. The default backup ownership is root:root. To facilitate export with SFTP or rsync, I'd like to change ownership to something like root:staff, root:backup, backup:staff, or backup:backup. Specifically: If a process uses SFTP to extract backups, it should not login as root, but it needs permissions to access these files. So I have a 'backup' user in group 'backup'. I've added this user to group 'staff'. The 'ubuntu' user is also in group 'staff' so that it can access /var/log files. So if backups are root:staff then I can use the user ubuntu or backup to get this data. Is there a reason that we should not change the ownership of those files or the process that runs the backup? If this is OK, can someone please point me to the code or settings where this change should be made? If this is NOT OK, I'm hoping suggestions will be made about the best way to do this. Would it be valid to suggest an enhancement to the system configuration page to allow entry for the user/group under which backups are created/saved? Thanks! EDIT: Temporary solution: I added user 'backup' to the 'root' group, and it can extract files. Of course I'm not fond of this solution.
