Linux Filesystem Backups with ALL_LOCAL_DRIVES

I want to cover the maximum file/folders available on a Redhat Linux 7 server. Which one should i use from below selection / with cross mount point enabled or ALL_LOCAL_DRIVES without cross mount. ...

    With ALL_LOCAL_DRIVES, you can select 'Allow Multiple data streams' in Policy Attributes.
    A separate backup stream will be created for each mount point.
    This way, when one stream fails, troubleshooting is easier and you can rerun the failed stream only.

For a server that is in a cluster, I won't do either.

When backing up the local hostnames, I would explicitly specify the non-shared mountpoints.

For clustered data, I would configure a policy for the virtual hostname with appropriate policy type to backup shared data.
e.g. - if Oracle is being clustered, configure Oracle policy to backup clustered instance.

If you backup a database with regular Standard policy, the backup will not be any good, because database files are in inconsistent state. Restoring the backed-up files will result in Oracle (or any other database type) failing to start.

Even if only file-level backups are needed, I would still configure a separate policy for the virtual hostname and shared mount points in Backup Selection. This way you are sure that the backup will follow the virtual hostname in case of a failover.

    Thanks for the resposne. This is basically an application server in cluster and app team want everything to be covered on both the nodes include cluster drives and os files. I will take backup of both the nodes with standard ALL_LOCAL_DRIVES in one policy so it should cover OS files from both nodes and cluster drives from active node.
