Server Settings

DB Backup

The following permissions need to be set globally for the backup user account.

  • SELECT
  • FILE
  • SHOW VIEW
  • SUPER
  • PROCESS
  • LOCK TABLES

Full Backup

Backups are done with rsync and sudo is used to back up all files.
For this reason, you need to be able to use sudo rsync with no-tty and no-password.

Add the following to the sudoers file on the remote server with visudo.

Defaults!/usr/bin/rsync !requiretty
USERNAME ALL=(ALL) NOPASSWD: /usr/bin/rsync

USERNAME must be the username to log in to the remote server.
This setting will allow you to retrieve all files that can be viewed as root (sudo) in the event of a successful SSH login with this account. If you are concerned about security issues, we recommend that you do not use this feature.
