Multistreaming Backup Options Multistreaming Backup Options If your CA ARCserve Backup server is equipped with multiple devices in two or more groups, or multiple devices in one or more groups with the CA ARCserve Backup Enterprise Module and CA ARCserve Backup Tape Library Option installed, you can use use the Multi Stream option to back up data. Multistreaming lets you divide backup jobs into several sub-jobs that run simultaneously to different devices. You can have as many jobs running simultaneously as you have devices or groups on your system. Database level and document level backups provide one stream per storage group for simultaneous backup. The number of available tapes, drives, and storage groups determine the number of streams that run simultaneously during the job. Note: You can enable Multistreaming on the Destination tab in the Backup Manager. If you enable the Multistreaming option when you submit a database level backup job, the data is multistreamed at the storage group level under two conditions: ■ You submit a local job under the Windows Systems object. ■ You submit a local job under the Exchange Organization object. Under all other conditions, database level backup data is multistreamed at the server level. For more information about Multistreaming, see the Administration Guide. Encrypt and Compress Backup Data The Encrypt data option lets you secure backup data. The Compress data option lets you efficiently use network resources and backup media. Note: For more information about data encryption and data compression, see the Administration Guide. You can apply the Encrypt data and Compress data options when you perform database level and document level backups. 110 Agent for Microsoft Exchange Guide
