Choosing the best way to archive your SnapManager backups

There are different methods for collecting the necessary parts of the SnapManager backup set for archiving. They each have their own advantages and disadvantages. Read the section for each method to decide which one works best for your organization. The three methods are as follows:

Use NDMP or the storage system's dump command to archive the LUNs containing the Exchange data and the SnapInfo directory directly from the storage system to the archive medium.
For more information about this method, see Using NDMP or dump to archive SnapManager backups.
Mount the LUNs in a SnapManager backup Snapshot copy and share it, then use NTBackup or another Windows backup utility to copy the LUNs' contents to the archive medium.
For more information about this method, see Using a Windows backup utility to archive SnapManager backups.
Create an Exchange copy-type backup directly to the archive medium using an Exchange-aware backup application.
