Continuous Backup

This is the manual for older MicroStream versions (Version < 5.0).

The new documentation (Version >= 5.0) is located at:

https://docs.microstream.one/

By default, the continuous backup is disabled. If enabled the MicroStream instance will clone all changes to another directory. The backup is identical to the primary MicroStream storage.

To enable the continuous backup just set the backup directory:

With storage.embedded.configuration API:

Java

EmbeddedStorageManager storageManager = Configuration.Default()
	.setBackupDirectory("A safe place")
	.createEmbeddedStorageFoundation()
	.createEmbeddedStorageManager();

Xml

<properties>
	<property name="backupDirectory" value ="/save/backup" />
	...
</properties>

ini

backupDirectory = backupDir

With MicroStream foundation classes:

Java

NioFileSystem      fileSystem  = NioFileSystem.New();
		
StorageBackupSetup backupSetup = StorageBackupSetup.New(
  Storage.BackupFileProviderBuilder(fileSystem)
		.setDirectory(fileSystem.ensureDirectoryPath(BACKUPDIR))						
		.setTruncationDirectory(fileSystem.ensureDirectoryPath(TRUNCATIONDIR))
		.setDeletionDirectory(fileSystem.ensureDirectoryPath(DELETIONDIR))
		.createFileProvider()
);	
				
StorageConfiguration configuration = StorageConfiguration.Builder()
	.setBackupSetup(backupSetup)
	.setStorageFileProvider(StorageLiveFileProvider.New(
	  fileSystem.ensureDirectoryPath(WORKINGDIR)
	))
	.createConfiguration()
;
