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 each profile 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
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.)
Estimating the space needed for the backup file using the web UI
Use the Backup and Restore page to estimate the space needed for the backup file.
Click the Settings tab.
Click Appliance Backup & Restore on the sidebar.
Select the profile you want to estimate. (See Database backup and restore introduction for descriptions.)
Click Estimate in the Estimate Backup column.
Details of the backup estimates for the selected profile are displayed.
Estimating the space needed for the backup file using the CLI
Use the commands in this section to estimate the space needed for the backup file.
Go to CLI enable mode.
hostname > enable
View the estimate for the type of backup profile.
To view the estimate for the configuration database, enter:
hostname # show backup estimate profile config
To view the estimate for the Trellix appliance database, enter:
hostname # show backup estimate profile fedb
To view the estimate for both the configuration database and the Trellix appliance database, enter:
hostname # show backup estimate profile config+fedb
To view the estimate for the configuration database, Trellix appliance database, and detected data (malware, alerts, reports, and so on), enter:
hostname # show backup estimate profile full
Example
The following example displays the estimates that are available for a full backup operation:
hostname # show backup estimate profile full ------------------------------------------------ # Estimates for full backup ------------------------------------------------ Local space available : 950462 MB Space reserved for other purposes : 502295 MB Space available for backups : 448167 MB Estimated space required for backup : 1736 MB Can perform local or remote backup : yes USB space available : 1764 MB Can perform USB backup : yes
