Review the Prerequisites and Considerations

Verify the following prerequisites before you back up more than 200 Linux nodes:

• Only 64-bit Linux is supported for the Backup Server
• The Backup Server must be a dedicated server. Arcserve UDP Agent (Linux) modifies the system settings to meet the high scalability requirement of the server.
• The server must meet the following minimum hardware requirements. If you have larger number of nodes, then the hardware specifications must be greater than the minimum requirements.
  • 8-GB memory
  • 10-GB free disk space for the /opt folder 

Review the following considerations:

• When you enable Arcserve UDP Agent (Linux) to back up more than 200 nodes, a new database (postgresql) is used by the server to meet the high scalability requirement. All existing node and job information in the old database (sqlite) are migrated to the new database, except the job history and the activity log. You cannot revert to the old database (sqlite) after the migration.
• After the migration, the output is displayed in a different format for the d2djobhistory command.
• As a best practice, one backup job should back up less than 1000 nodes.
