Performance for remote backup is improved through RPC enhancements. The examples in the following sections illustrate when immediate save is invoked, and when it cannot be invoked.

Power Edition Local Backup and Recover

When one computer includes both client and server or storage node software, with storage devices attached, the data is backed up using immediate save. FIGURE 2-1 shows an example of local backup of a Power Edition server. Power Edition can back up data of any type supported by a Backup client, including a range of databases.

Local Backup and Recover

FIGURE 2-1

Backup is faster in this setup for Power Edition than for the Backup base product, because Power Edition can use the immediate save technology. Processes and data that travel through a protocol stack in a standard Backup setup are instead passed in memory on the same computer. The network transmission bottleneck is eliminated. The same is true for recover operations.
If the database is offline, any database can take advantage of immediate save for local backup with a Backup client. Some Solstice Database Module clients can also take advantage of immediate save for online database backups. Refer to the documentation you received with your Database Module to determine whether immediate save for online backup is currently supported.
