To make a backup, renaming the transaction log (SQL)

• Use the BACKUP statement with the following clauses:

  BACKUP DATABASE DIRECTORY backup-directory [ TRANSACTION LOG ONLY ] TRANSACTION LOG RENAME;

  Include the TRANSACTION LOG ONLY clause only if you are making an incremental backup.

  The backup copies of the transaction log and database file are placed in backup-directory. If you enter a path, it is relative to the working directory of the database server, not your client application.

To make a backup, renaming the transaction log (command line)

• Run the following command (it must be typed on one line):

  dbbackup -c "connection-string" -r [ -t ] backup-directory

  Include the -t option if you are making an incremental backup.

  The backup copies of the transaction log and database file are placed in backup-directory. If you enter a path, it is relative to the directory from which you run the command.
