20.4.1 Back up all data periodically

Make sure that your disaster recovery plan includes a regularly scheduled complete backup of all NNMi data. You do not need to shut down NNMi to create this backup. If you incorporate the backup into a script, you can use the -force option to ensure that NNMi is in the correct state before the backup begins.

Example:

nnmbackup.ovpl -force -type online -scope all -archive -target nnmi_backups\periodic

To recover your NNMi data after a hardware failure, follow these steps:

1. Repair or replace the failed hardware.

2. Install NNMi to the same version and patch level as were in place at the time of the backup.

3. Restore the NNMi data.

   • If the recovery NNMi management server satisfies the requirements listed in 20.3.1 Same-system restore, run a command similar to the following example:

   nnmrestore.ovpl -force -lic -source nnmi_backups\periodic\newest_backup

   • If the recovery NNMi management server does not qualify for a same-system restore but satisfies the requirements listed in 20.3.2 Different-system restore, run a command similar to the following example:

   nnmrestore.ovpl -force -source nnmi_backups\periodic\newest_backup

   Update the licensing as needed.
