Disaster recovery emails and the disaster recovery files
The Catalog Backup Wizard and the Policy Configuration Wizard prompt you to send the disaster recovery information to an email address. If the catalog backup is configured manually using the Policy utility, this information appears on the Disaster Recovery tab.
The disaster recovery email and the accompanying attachments that are sent contain the following important items for a successful catalog recovery:
A list of the media that contains the catalog backup.
A list of critical policies.
Instructions for recovering the catalog.
The image file as an attachment.
If a catalog backup policy included both full backups and incremental backups, the attached image file can be a full or an incremental catalog backup.
Recovering from an incremental catalog backup completely recovers the entire catalog if the option is selected on the wizard panel. The entire catalog is recovered because the incremental catalog backup references information from the last full backup. You do not need to recover the last full catalog backup before you recover the subsequent incremental backups.
The disaster recovery package file as an attachment.
Note:
If you are not able to receive the disaster recovery packages over emails even after the disaster recovery email configuration, and then ensure the following:
Your email exchange server is configured to have the attachment size equal to or greater than the disaster recovery package size. You can check the size of the package (.drpkg file size) on the disaster recovery file location that you have specified in the catalog backup policy.
The firewall and the antivirus software in your environment allows the files with the .drpkg extension (which is the extension of a disaster recovery package file).
NetBackup emails the disaster recovery file when the following events occur:
The catalog is backed up.
A catalog backup is duplicated or replicated.
The primary catalog backup or any copy expires automatically or is expired manually.
On Windows: You can tailor the disaster recovery email process by providing the mail_dr_info.cmd script in the install_path\Veritas\NetBackup\bin directory. This script is similar to the nbmail.cmd script. See the comments in the nbmail.cmd script for use instructions.
