Use the following tips to decide which compression method is better for your environment:
*Use compressasmto minimize network bandwidth, if you have available CPU
power.
*Use compressasmor compressing drives to get more data on a tape. *Trying to compress data that has already been compressed provides no additional
compression. You can use compressing drives andcompressasm, but do not
expect additional compression on the tape. Selecting both options might even
expand the data.
*Do not use compressasmif you have a compressing drive and no networked
clients.

Storage Nodes, Remote Devices, and Multiple Network Interfaces

You can control most operations on local and remote devices, including autochangers and silos, from the Backup administration program on the server. But for some remote autochanger operations (for example, reset) you must use the nsrjbcommand or the jb_configprogram on the storage node machine. During data transfer operations, the Backup server uses remote devices the same way it uses local devices.

Caution - Backup clients at release 4.2 and later are able to use remote devices for backup, archive, and HSM (hierarchical storage management) functions. Earlier Backup clients cannot back up data to remote devices.

This section also discusses network interfaces. You can change the default network interfaces. You can also direct different clients to different network interfaces into the same storage node.

Remote Device Configuration

You configure remote standalone devices in an administration session with the controlling Backup server the same way you configure a standalone device that is connected to the Backup server. When you create each device, add a prefix to the device name that includes rd=and the storage node's hostname. For example,
