NetBackup™ in Highly Available Environments Administrator's Guide

To prepare for partial catalog restore

1. Run the nbgetconfig command and save the output. This output can be used after the catalog recovery to recover the host-specific information that is overwritten during the catalog recovery.

   For example:

   ./nbgetconfig > sample.txt

2. Recover only the NetBackup catalog image and configuration files.

   • Select the Partial catalog recovery option when prompted.

   • Or run the bprecover -wizard command. When you are prompted "Do you want to recover the entire NetBackup catalog? (Y/N)", enter N.

   Note:

   The DR primary server must have the same name as the production primary server.

   Note:

   If a catalog backup that was created on a separate media server is used, a media server with the same name is required for the catalog recovery.

3. If you want to recover the image header information without recovering the entire NetBackup database, perform the following steps:

   • Step a - Back up the target database. Run the following command.

     nbdb_backup -online directory

     Make sure that you do not specify the staging folder as the output directory. (The staging folder contains the schema data and configuration data for the NetBackup database from the catalog backup. Image .f and configuration files are recovered to their final destinations.)

   • Step b - Recover the NetBackup database from the staging directory.

     nbdb_restore -recover -staging

   • Step c - Export the image header data that you want to import from the backup.

     For example, the following command exports export all image header data. The data is exported to the netbackup/db.export directory.

     cat_export -all

   • Step d- Recover the NetBackup database with the following command.

     nbdb_restore -recover directory

     Make sure that you specify the same directory as in step a.

   • Step e- Run the cat_import command to import the image header data that you extracted in step c.

     cat_import -all -replace_destination -delete_source

     The command does the following:

     • Imports all of the image header data in the netbackup/db.export directory.

     • Replaces any image header data that was exported that already exists in the target database.

     • Removes the image header data that resides in the netbackup/db.export directory.

   • Step f- If you recovered the catalog from a disk device, you may have to fix the disk media ID references. Run the following command:

     nbcatsync -sync_dr_file DR file path -dryrun

     Replace DR file path with the path to the catalog DR file.

   • Step g - If the result of the dry run is satisfactory, run the following command:

     nbcatsync -sync_dr_file DR file path

4. Deactivate all the backup policies to prevent backups from starting automatically, in one of the following ways.

   • In the NetBackup web UI.

   • Run the bpplinfo <policy> -modify -inactive CLI.

5. Shut down NetBackup.
6. Recover the host settings that you backed up in step 1. Run the following command.

   ./nbsetconfig sample.txt

7. Start NetBackup.
8. Inventory all the tape libraries to ensure that the tapes are added to the non-scratch media pool. This pool prevents tapes from being accidentally overwritten by active backup policies at a later time.
