Global Dashboard Data Storage Requirements

In a Global Dashboard environment, the collected dashboard data (Arcserve Backup data and SRM-related data) from each registered Branch Primary Server is synchronized to the configured Central Primary Server, where it is stored in the central Arcserve Backup database (ASDB). As a result, when selecting the Central Primary Server, the main consideration should be database size. Make sure the selected Central Primary Server is capable of storing dashboard data received from all registered Branch Primary Servers.

Note: For a Branch Primary Server, no additional hardware or software is required beyond the minimum requirements for any Arcserve Backup primary server or stand-alone server.

To calculate the approximate amount of space required for the central ASDB in your Global Dashboard environment, consider the following:

• As each branch site uploads data to the central ASDB on a daily basis, it is estimated that the central ASDB will grow by approximately 4 MB for every 100 nodes (assuming 4 volumes in each node) every day (or 1MB for every 100 sessions every day).
• The number of sessions is calculated by multiplying the number of nodes by the average number of volumes in a node. The number of days of database retention time is determined by the branch Arcserve Backup setup.
• You can calculate the approximate required disk space at the central site by multiplying the estimated daily ASDB growth (1MB for every 100 sessions) by the number of days of database retention time.

  For example:

  If you have 10 branch sites with each site having 10 nodes and each node contains 4 volumes, then the central ASDB will grow by 4MB every day. If the database record is retained for 180 days, then the central ASDB will need to be 720MB.

  • 10 branch sites x 10 nodes x 4 volumes = 400 sessions
  • 400 sessions = 4MB database space growth per day (1MB per 100 sessions)
  • 4MB daily growth x 180 database retention days = 720MB total database space required for the central ASDB

  Note: Any database pruning that is performed at a branch ASDB will be reflected in the central ASDB the next time data synchronization is performed.
