Delete backup positional parameters

Positional parameters immediately follow the delete backup command and precede the optional parameters.

The following positional parameters specify the backup to delete:

*|dbname1,...,dbnameN backuptype

*: Delete the active backups of all databases.
dbname: Delete a backup of the specified database. The active backup is deleted unless you specify a different backup with the /object parameter. When multiple active incremental backups exist, the /object parameter must be specified with the delete command.; Multiple entries are separated by commas. If separated by commas, ensure that there is no space between the comma and the component name. If any component name contains blanks, enclose the component name in double quotation marks.

Attention:

Deleting incremental or differential backups can cause loss of recovery points.
Deleting a full backup might cause incremental or differential backups to remain in a suspended state and are considered useless without a corresponding full backup.

The following positional parameters specify the type of delete backup to run:

FULL|COPY|INCRemental|DIFFerential
