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/

Continuous Backup

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:

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

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

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()
;
