Constructor Detail

FBNBackupManager

public FBNBackupManager()

Create a new instance of FBNBackupManager based on the default GDSType.

FBNBackupManager

public FBNBackupManager(java.lang.String gdsType)

Create a new instance of FBNBackupManager based on a given GDSType name.

Parameters:

gdsType - type must be PURE_JAVA, EMBEDDED, or NATIVE

FBNBackupManager

public FBNBackupManager(GDSType gdsType)

Create a new instance of FBNBackupManager based on a given GDSType.

Parameters:

gdsType - type must be PURE_JAVA, EMBEDDED, or NATIVE

Method Detail

setBackupFile

public void setBackupFile(java.lang.String backupFile)

Description copied from interface: NBackupManager

Sets the location of the backup file.

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

Specified by:

setBackupFile in interface NBackupManager

Parameters:

backupFile - the location of the backup file.

addBackupFile

public void addBackupFile(java.lang.String backupFile)

Description copied from interface: NBackupManager

Add additional backup files.

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

Use NBackupManager.clearBackupFiles() to clear earlier backup files.

Specified by:

addBackupFile in interface NBackupManager

Parameters:

backupFile - the location of the backup file.

clearBackupFiles

public void clearBackupFiles()

Description copied from interface: NBackupManager

Clear the information about backup files. This method undoes all parameters set in the NBackupManager.addBackupFile(String) method.

Specified by:

clearBackupFiles in interface NBackupManager

backupDatabase

public void backupDatabase()
                    throws java.sql.SQLException

Description copied from interface: NBackupManager

Perform the backup operation.

Specified by:

backupDatabase in interface NBackupManager

Throws:

java.sql.SQLException - if a database error occurs during the backup

restoreDatabase

public void restoreDatabase()
                     throws java.sql.SQLException

Description copied from interface: NBackupManager

Perform the restore operation.

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

Specified by:

restoreDatabase in interface NBackupManager

Throws:

java.sql.SQLException - if a database error occurs during the restore

See Also:

NBackupManager.restoreDatabase()

fixupDatabase

public void fixupDatabase()
                   throws java.sql.SQLException

Description copied from interface: NBackupManager

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

Specified by:

fixupDatabase in interface NBackupManager

Throws:

java.sql.SQLException - if a database error occurs during the fixup

setBackupLevel

public void setBackupLevel(int backupLevel)

Description copied from interface: NBackupManager

Sets the backup level (0 = full, 1..n = incremental)

Specified by:

setBackupLevel in interface NBackupManager

Parameters:

backupLevel - backup level (e.g. 0 = full backup, 1 = level 1 incremental backup based on level 0 backup

setBackupGuid

public void setBackupGuid(java.lang.String guid)

Description copied from interface: NBackupManager

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 NBackupManager.setBackupLevel(int), but this is only checked server-side.

Specified by:

setBackupGuid in interface NBackupManager

Parameters:

guid - A GUID string of a previous backup, enclosed in braces.

setNoDBTriggers

public void setNoDBTriggers(boolean noDBTriggers)

Description copied from interface: NBackupManager

Sets the option no database triggers when connecting at backup or in-place restore.

Specified by:

setNoDBTriggers in interface NBackupManager

Parameters:

noDBTriggers - true disable db triggers during backup or in-place restore.

setInPlaceRestore

public void setInPlaceRestore(boolean inPlaceRestore)

Description copied from interface: NBackupManager

Enables in-place restore.

Specified by:

setInPlaceRestore in interface NBackupManager

Parameters:

inPlaceRestore - true to enable in-place restore

setPreserveSequence

public void setPreserveSequence(boolean preserveSequence)

Description copied from interface: NBackupManager

Enables preserve sequence (for fixup or restore).

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

Specified by:

setPreserveSequence in interface NBackupManager

Parameters:

preserveSequence - true to enable preserve sequence

setCleanHistory

public void setCleanHistory(boolean cleanHistory)

Description copied from interface: NBackupManager

Enables clean history on backup.

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

Specified by:

setCleanHistory in interface NBackupManager

Parameters:

cleanHistory - true to enable clean history

setKeepDays

public void setKeepDays(int days)

Description copied from interface: NBackupManager

Sets the number of days of backup history to keep.

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

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

Specified by:

setKeepDays in interface NBackupManager

Parameters:

days - number of days to keep history when cleaning, or -1 to clear current value

See Also:

NBackupManager.setCleanHistory(boolean), NBackupManager.setKeepRows(int)

setKeepRows

public void setKeepRows(int rows)

Description copied from interface: NBackupManager

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 NBackupManager.setKeepDays(int), this is not enforced by the Java code.

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

Specified by:

setKeepRows in interface NBackupManager

Parameters:

rows - number of rows to keep history when cleaning, or -1 to clear current value

See Also:

NBackupManager.setCleanHistory(boolean), NBackupManager.setKeepDays(int)
