Estimating the space needed for the backup file

Prev Next

The appliance estimates the size of the backup file and calculates the amount of space it needs. The available space must be greater than the estimated space required to perform the backup operation. The size depends on the profile you select (described in Database backup and restore introduction ).

Details of the backup estimates for the configuration database include the following:

  • Size estimate of the database file based on the backup profile

  • Available space based on the backup profile

  • Whether the backup can be performed

Prerequisites
  • Admin access to run the estimate

  • Monitor, Operator, or Admin access to view the backup estimate using the CLI. (In the Web UI, these roles can view only existing backup files, not the backup estimate.)
