Our company uses Bacula Enterprise to ensure that our servers, projects, and files are being backed up reliably. Our strategy includes making virtual machine backups to facilitate restoring complete systems as well as making file level backups to restore files one-by-one. We also use Bacula Enterprise to back up our active directory database and our Microsoft Exchange email. Bacula Enterprise can be customized to the extreme, and we take advantage of this by creating backup jobs that are exactly suited for each situation -- in some cases we need to keep files for years and in other cases we are only concerned about having a reasonably recent backup. Although Bacula Enterprise could be used on individual user's computers, our disaster recovery plan only requires that our servers be backed up. We do not use tape. Our backups are stored locally to disk and then replicated off-site.
