  • Method Details

    • setBackupFile

      void setBackupFile(String backupFile)
      Sets the location of the backup file.

      Warning: this method behaves identical to addBackupFile(String).

      Parameters:
      backupFile - the location of the backup file.
    • addBackupFile

      void addBackupFile(String backupFile)
      Add additional backup files.

      Specifying multiple backup files is only valid for restore, for backup only the first file is used.

      Use clearBackupFiles() to clear earlier backup files.

      Parameters:
      backupFile - the location of the backup file.
    • clearBackupFiles

      void clearBackupFiles()
      Clear the information about backup files. This method undoes all parameters set in the addBackupFile(String) method.
    • setDatabase

      void setDatabase(String path)
      Set the path to the database. This method is used both for backup and restore operation.
      Specified by:
      setDatabase in interface ServiceManager
      Parameters:
      path - path to the database file.

      In case of backup, value specifies the path of the existing database on the server that will be backed up.

      In case of restore, value specifies the path of the database where the backup will be restored to.

    • backupDatabase

      void backupDatabase() throws SQLException
      Perform the backup operation.
      Throws:
      SQLException - if a database error occurs during the backup
    • restoreDatabase

      void restoreDatabase() throws SQLException
      Perform the restore operation.

      Set setPreserveSequence(boolean) to preserve the original database GUID and replication sequence.

      Throws:
      SQLException - if a database error occurs during the restore
    • fixupDatabase

      void fixupDatabase() throws SQLException
      Perform the nbackup fixup operation.

      A fixup will switch a locked database to 'normal' state without merging the delta, so this is a potentially destructive action. The normal use-case of this option is to unlock a copy of a database file where the source database file was locked with nbackup -L or ALTER DATABASE BEGIN BACKUP.

      Set setPreserveSequence(boolean) to preserve the original database GUID and replication sequence.

      Throws:
      SQLException - if a database error occurs during the fixup

    • setBackupLevel

      void setBackupLevel(int level)
      Sets the backup level (0 = full, 1..n = incremental)
      Parameters:
      level - backup level (e.g. 0 = full backup, 1 = level 1 incremental backup based on level 0 backup
    • setBackupGuid

      void setBackupGuid(String guid)
      Sets the backup GUID (Firebird 4 and higher only).

      The backup GUID is the GUID of a previous backup of the (source) database. This is used by Firebird to backup the pages modified since that backup.

      This setting is mutually exclusive with setBackupLevel(int), but this is only checked server-side.

      Parameters:
      guid - A GUID string of a previous backup, enclosed in braces.
      Since:
      4.0.4
    • setNoDBTriggers

      void setNoDBTriggers(boolean noDBTriggers)
      Sets the option no database triggers when connecting at backup or in-place restore.
      Parameters:
      noDBTriggers - true disable db triggers during backup or in-place restore.
    • setInPlaceRestore

      void setInPlaceRestore(boolean inPlaceRestore)
      Enables in-place restore.
      Parameters:
      inPlaceRestore - true to enable in-place restore
      Since:
      4.0.4
    • setPreserveSequence

      void setPreserveSequence(boolean preserveSequence)
      Enables preserve sequence (for fixup or restore).

      This preserves the existing GUID and replication sequence of the original database (they are reset otherwise).

      Parameters:
      preserveSequence - true to enable preserve sequence
      Since:
      5
    • setCleanHistory

      void setCleanHistory(boolean cleanHistory)
      Enables clean history on backup.

      The backup will fail if setKeepDays(int) or setKeepRows(int) has not been called.

      Parameters:
      cleanHistory - true to enable clean history
      Since:
      4.0.7
    • setKeepDays

      void setKeepDays(int days)
      Sets the number of days of backup history to keep.

      Server-side, this option is mutually exclusive with setKeepRows(int), this is not enforced by the Java code.

      This option only has effect when setCleanHistory(true) has been called.

      Parameters:
      days - number of days to keep history when cleaning, or -1 to clear current value
      Since:
      4.0.7
      See Also:
    • setKeepRows

      void setKeepRows(int rows)
      Sets the number of rows of backup history to keep (this includes the row created by the backup).

      Server-side, this option is mutually exclusive with setKeepDays(int), this is not enforced by the Java code.

      This option only has effect when setCleanHistory(true) has been called.

      Parameters:
      rows - number of rows to keep history when cleaning, or -1 to clear current value
      Since:
      4.0.7
