Disaster recovery best practices
NetBackup offers a few different configuration options that can help aid in a disaster
recovery process if a disaster strikes.
Note: Use the following topology configurations as a general guide. Contact your
Symantec account representative to establish what topology configuration best fits
your particular environment.
Single domain configuration:
■ Create the appliance Master as a virtual machine, using Site Recovery Manager
to replicate data from the protected site to the recovery site.
■ Store catalog backups at an off-site location in case a recovery is necessary.
You can use tape or cloud for restoration to a rebuilt master server at the disaster
recovery site.
■ Configure a setup using VCS Global Cluster Option. Global Cluster Option to
VCS enables linking clusters from separate locations together and connecting
applications across clusters. This connection provides complete service level
protection against an entire site failure by providing applications failover to the
remote site.
An application is installed and configured on both clusters-local and remote, but
is online on a system in local cluster and is configured to fail over globally on
the remote cluster. The data is located on shared disks within each cluster and
is replicated across clusters to ensure data concurrency.
In an event of a disaster affecting an entire region, one can create a
comprehensive Disaster Recovery solution by combining the capabilities of
application clustering with data replication.
Note: Clustering environments are not supported on the NetBackup appliance.
Multi-domain configuration:
■ Configure Auto Image Replication to replicate backups that are generated in
one NetBackup domain to storage in another NetBackup domain.
