NetBackup disaster recovery email example
A catalog backup policy can send a disaster recovery email upon completion of a catalog backup. To configure a catalog backup policy, see the NetBackup Administrator's Guide, Volume I:
http://www.veritas.com/docs/DOC5332
The following is an example of a disaster recovery email after a successful catalog backup:
From: NetBackup@example.com Sent: Thursday, January 3, 2019 05:48 To: NetBackup Administrator Subject: NetBackup Catalog Backup successful on host master.example.com status 0 Attachments: cat_backup_1438271286_INCR cat_backup_1438271286_INCR.drpkg Server master.example.com NetBackup Version 8.1.X Date 4/27/2017 05:46:45 AM Policy cat_backup Catalog Backup Status the requested operation was successfully completed (status 0). WARNING: External CA-signed certificates could not be backed up. Refer to the following article to configure external CA-signed certificates on the host after disaster recovery installation: https://www.veritas.com/support/en_US/article.100044249 DR image file: /dr/nbu_dr_file/cat_backup_1438271286_INCR To ensure that the NetBackup catalog data is protected through 1/3/2019 10:46:45 AM, retain a copy of each attached file, and the media or files listed below: Catalog Recovery Media Media Server Disk Image Path Image File Required * media-server.example.com @aaaab cat_backup_1438267080_FULL * media-server.example.com @aaaab cat_backup_1438271206_INCR * media-server.example.com @aaaab cat_backup_1438271286_INCR DR file written to /dr/nbu_dr_file/cat_backup_1438271286_INCR DR Package file written to /dr/nbu_dr_file/cat_backup_1438271286_INCR.drpkg The CA configuration at the time of catalog backup is as follows: The master server ch12auto28 is configured to use NetBackup and external CA-signed certificates. ECA_CERT_PATH = MY\\ch12auto28.pne.ven.veritas.com ECA_CRL_PATH = C:\Users\Administrator\Downloads\divgrt1.crl ECA_CRL_PATH_SYNC_HOURS = 1 ECA_CRL_REFRESH_HOURS = 24 ECA_CRL_CHECK = 1 ECA_DR_BKUP_WIN_CERT_STORE = YES * - Primary Media Catalog Recovery Procedure for the Loss of an Entire Catalog You should create a detailed disaster recovery plan to follow should it become necessary to restore your organization's data in the event of a disaster. A checklist of required tasks can be a tremendous tool in assisting associates in triage. For example, after the facility is safe for data to be restored, the power and data infrastructure need to be verified. When these tasks are completed, the following scenarios will help to quickly restore the NetBackup environment, and in turn, restore applications and data. Disaster Recovery Procedure using the DR Package file and DR Image File In the event of a catastrophic failure, use the following procedure to rebuild the previous NetBackup environment. Important Notes: - If new hardware is required, make sure that the devices contain drives capable of reading the media and that the drive controllers are capable of mounting the drives. - Keep the passphrase associated with the DR Package file handy. This passphrase is set before the catalog backup policy configuration using the NetBackup Administration Console or the nbseccmd command. 1. Install NetBackup. a. The installation procedure prompts you to confirm if this is a DR scenario. i. On the UNIX installer, you can see a prompt as "Do you want to do a disaster recovery on this master server? [y,n] (y)". Select "y" ii. On the Windows installer click the "Disaster Recovery Master Server" button. b. The installation procedure prompts you for the master server's DR Package (refer to the /dr/nbu_dr_file/cat_backup_1438271286_INCR.drpkg mentioned earlier). Make sure that the Master Server can access the attached DR package file. c. Type the passphrase associated with the Master Server's DR Package, when prompted. i. The installer validates the DR package using that passphrase ii. In case of errors in validation, the installer aborts the operation. To work around the issue, refer to the following article: http://www.veritas.com/docs/000125933 2. Configure the devices necessary to read the media listed above. 3. Inventory the media. 4. Make sure that the master server can access the attached DR image file. 5. Start the NetBackup Recovery Wizard from the NetBackup Administration Console. Or, start the wizard from a command line by entering bprecover -wizard. WARNING: CRLs are not backed as part of the DR package backup. Refer to the following article to manually add the CRLs: https://www.veritas.com/support/en_US/article.100044250 Disaster Recovery Procedure without the DR Image File NOTE: ONLY ATTEMPT THIS AS A LAST RESORT If you do not have the attachment included with this email, use the following instructions to recover your catalog. (If using OpenStorage disk pools, refer to the Shared Storage Guide to configure the disk pools instead of step 2 and 3 below ): 1. Install NetBackup. 2. Configure the devices necessary to read the media listed above. 3. Inventory the media. 4. Run To recover from copy 1: bpimport -create_db_info -stype AdvancedDisk -dp dp-advdisk -dv /storage/advdisk 5. Run: cat_export -client client1.example.com 6. Go to the following directory to find the DR image file cat_backup_1438271286_INCR: /usr/openv/netbackup/db.export/images/master.example.com/1438000000 7. Open cat_backup_1438271286_INCR file and find the BACKUP_ID (for example: master.example.com_1438271286). 8. Run: bpimport [-server name] -backupid master.example.com_1438271286 9. Run: bprestore -T -w [-L progress_log] -C master.example.com -t 35 -p cat_backup -X -s 1438271286 -e 1438271286 / 10. Run the BAR user interface to restore the remaining image database if the DR image is a result of an incremental backup. 11. To recover the NetBackup relational database, run: bprecover -r -nbdb 12. Stop and Start NetBackup. 13. Configure the devices if any device has changed since the last backup. 14. To make sure the volume information is updated, inventory the media to update the NetBackup database.
