Monitoring file systems backup

Hello,
I have some questions.
There are some File systems which are located on a SAN. There are two scenarios:
1) Some file systems are permanently mounted on certain servers
2) Others are part of a high availability cluster

In case of a cluster the needed file systems for a certain application are all visible to all cluster nodes (cluster servers) at the same time. A certain node is assigned to primarily run a certain service. Therefore it mounts the file system and provides the service as a new, virtual IP. The trick is now, that the virtual IP and virtual name can also be brought up by another cluster node in case the first one fails. This by itself is not a problem but it has turned out that this provides a problem for the backup because the backup is naturally file system oriented. From a user (or calling services) perspective the user only talks to the virtual IP and name, which never changes. He has no idea that this IP is in reality running on a physical cluster node with its own IP and name and on top of that the cluster nodes can even change.

by the default log file, I just get the machine names, mount points, full backup and incremental backups.

Now the question is how to be sure if file systems are correctly backed up?


I can think of some aproached:
1- check the list of file system and check the list of backed up files and compare to see if those FS are in back up. we pay attention to timestamp
2- the same as above but this time comparing also the size
3- check if machines in general are backed up
4- MD5 checksum

can someone give me any other idea and in general some suggestion?

Thanks

NAME
cmdeleteconf - Delete either the cluster or the package configuration SYNOPSIS
cmdeleteconf [-f] [-v] [-c cluster_name] [[-p package_name]...] DESCRIPTION
cmdeleteconf deletes either the entire cluster configuration, including all its packages, or only the specified package configuration. If neither cluster_name nor package_name is specified, cmdeleteconf will delete the local cluster's configuration and all its packages. If the local node's cluster configuration is outdated, cmdeleteconf without any argument will only delete the local node's configuration. If only the package_name is specified, the configuration of package_name in the local cluster is deleted. If both cluster_name and pack- age_name are specified, the package must be configured in the cluster_name, and only the package package_name will be deleted. cmdelete- conf with only cluster_name specified will delete the entire cluster configuration on all the nodes in the cluster, regardless of the con- figuration version. The local cluster is the cluster that the node running the cmdeleteconf command belongs to. Only a superuser, whose effective user ID is zero (see id(1) and su(1)), can delete the configuration. To delete the cluster configuration, halt the cluster first. To delete a package configuration you must halt the package first, but you do not need to halt the cluster (it may remain up or be brought down). To delete the package VxVM-CVM-pkg (HP-UX only), you must first delete all packages with STORAGE_GROUP defined. While deleting the cluster, if any of the cluster nodes are powered down, the user can choose to continue deleting the configuration. In this case, the cluster configuration on the down node will remain in place and, therefore, be out of sync with the rest of the cluster. If the powered-down node ever comes up, the user should execute the cmdeleteconf command with no argument on that node to clean up the config- uration before doing any other Serviceguard command. Options cmdeleteconf supports the following options: -f Force the deletion of either the cluster configuration or the package configuration. -v Verbose output will be displayed. -c cluster_name Name of the cluster to delete. The cluster must be halted already, if intending to delete the cluster. -p package_name Name of an existing package to delete from the cluster. The package must be halted already. There should not be any packages in the cluster with STORAGE_GROUP defined before having a package_name of VxVM-CVM-pkg (HP-UX only). RETURN VALUE
Upon completion, cmdeleteconf returns one of the following values: 0 Successful completion. 1 Command failed. EXAMPLES
The high availability environment contains the cluster, clusterA , and a package, pkg1. To delete package pkg1 in clusterA, do the following: cmdeleteconf -f -c clusterA -p pkg1 To delete the cluster clusterA and all its packages, do the following: cmdeleteconf -f -c clusterA AUTHOR
