Incremental Backup options
If Incremental backup is specified as the backup type, you need to set specific incremental backup (Online Dump) options.
Use local utilities
Select this option to backup the database using local utilities.
Note: To enable this mode, you need to specify the location of the utilities in the Path to database utilities field on the Connection page of the Host Registration Info dialog, and gbak.exe and nbackup.exe (for Firebird multi-level backup) files must exist in this directory.
Select this option to use the server services for the backup operation.
Overwrite old file
This option is available only for Interbase 2009 or higher. If you enable this option, the utility will completely overwrite the old backup file. Otherwise the new backup file will contain only changes relatively to the previous backup.
Generate backup name
Check this option if you need backup file name to be generated automatically.
Specify the level of the backup. Note that you cannot make a level n backup if level n-1 backup of this database does not exist in backup history. Only level 0 backup can be created without any restrictions.
Note: This option is only available for Firebird 2.0 or higher. The option is available if the location of the utilities is specified in the Path to database utilities field on the Connection page of the Host Registration Info dialog, and nbackup.exe file exists in this directory. Moreover, the server must be registered locally.
