When you create a storage policy, a media agent with associated
storage is selected as part of the policy.
Without further care, if the media agent goes offline, the backups will
fail. However, using the GridStor®
features of Simpana, alternate data paths can be configured if the media agent
goes offline or if the storage becomes unavailable allowing for your backups to
continue after a failure.
When you create a storage policy, you select a default data
path for their backups. If you have a 2nd
Media agent in your CommVault environment, you can define an alternate data
path. When creating alternate data
paths, you have two options. The first
is use alternate data paths when the
resources are offline
. This will
allow the alternate data path to be used when the media agent is offline or unavailable
in some way, like a network outage. The
second option is to use alternate data paths when resources are busy
. This will allow the alternate data path to
be used when the media agent is out of space or is in use with another
job. Multiple alternate paths can be
selected to further protect your backup jobs.
