Description
The class implementing Firebird-only database restore service.
Use the TFDFBNRestore component to add a Firebird-only restore from backup database capability to an application. This is a programmatic method to invoke the nbackup tool as a thread in the DB server process to restore a database.
To configure the connection to the database server, you must fill the following properties: DriverLink, Host, Protocol, UserName and Password.
To restore a database from a DB backup, an application should:
- Specify Database - a primary database file to restore.
- Specify BackupFiles - the file names to restore a database from.
- Call Restore method.
Other properties and methods are optional.
Paths of backup files are relative to the server. Because TFDFBNBackup restores a backup on the DB server host, the DB Service Manager reads backup files from the server host.
Read http://www.firebirdsql.org/manual/nbackup.html for more details.
Example
FDFBNRestore1.DriverLink := FDPhysFBDriverLink1; FDFBNRestore1.UserName := 'sysdba'; FDFBNRestore1.Password := 'masterkey'; FDFBNRestore1.Host := 'db_srv_host'; FDFBNRestore1.Protocol := ipTCPIP; FDFBNRestore1.Database := 'e:\fb\addemo.fdb'; FDFBNRestore1.BackupFile := 'e:\fb\addemo.backup'; FDFBNRestore1.Restore;
