Definition

Namespace:

Microsoft.ServiceFabric.Actors.Runtime

Assembly:

Microsoft.ServiceFabric.Actors.dll

Package:

Microsoft.ServiceFabric.Actors v6.1.1583

Overloads

IStateProviderReplica.BackupAsync(Func<BackupInfo,CancellationToken,Task<Boolean>>)	Performs a full backup of all reliable state managed by this actor sate provider.
IStateProviderReplica.BackupAsync(BackupOption, TimeSpan, CancellationToken, Func<BackupInfo,CancellationToken,Task<Boolean>>)	Performs backup of reliable state managed by this actor sate provider.

IStateProviderReplica.BackupAsync(Func<BackupInfo,CancellationToken,Task<Boolean>>)

Performs a full backup of all reliable state managed by this actor sate provider.

System.Threading.Tasks.Task IStateProviderReplica.BackupAsync (Func<Microsoft.ServiceFabric.Data.BackupInfo,System.Threading.CancellationToken,System.Threading.Tasks.Task<bool>> backupCallback);

abstract member Microsoft.ServiceFabric.Data.IStateProviderReplica.BackupAsync : Func<Microsoft.ServiceFabric.Data.BackupInfo, System.Threading.CancellationToken, System.Threading.Tasks.Task<bool>> -> System.Threading.Tasks.Task
override this.Microsoft.ServiceFabric.Data.IStateProviderReplica.BackupAsync : Func<Microsoft.ServiceFabric.Data.BackupInfo, System.Threading.CancellationToken, System.Threading.Tasks.Task<bool>> -> System.Threading.Tasks.Task

Function BackupAsync (backupCallback As Func(Of BackupInfo, CancellationToken, Task(Of Boolean))) As Task Implements IStateProviderReplica.BackupAsync

Parameters

backupCallback

Func<BackupInfo,CancellationToken,Task<Boolean>>

Callback to be called when the backup folder has been created locally and is ready to be moved out of the node.

Returns

Task

Task that represents the asynchronous backup operation.

Implements

BackupAsync(Func<BackupInfo,CancellationToken,Task<Boolean>>)

Remarks

A FULL backup will be performed with a one-hour timeout. Boolean returned by the backupCallback indicate whether the service was able to successfully move the backup folder to an external location. If false is returned, BackupAsync throws InvalidOperationException with the relevant message indicating backupCallback returned false. Also, backup will be marked as unsuccessful.

IStateProviderReplica.BackupAsync(BackupOption, TimeSpan, CancellationToken, Func<BackupInfo,CancellationToken,Task<Boolean>>)

Performs backup of reliable state managed by this actor sate provider.

System.Threading.Tasks.Task IStateProviderReplica.BackupAsync (Microsoft.ServiceFabric.Data.BackupOption option, TimeSpan timeout, System.Threading.CancellationToken cancellationToken, Func<Microsoft.ServiceFabric.Data.BackupInfo,System.Threading.CancellationToken,System.Threading.Tasks.Task<bool>> backupCallback);

abstract member Microsoft.ServiceFabric.Data.IStateProviderReplica.BackupAsync : Microsoft.ServiceFabric.Data.BackupOption * TimeSpan * System.Threading.CancellationToken * Func<Microsoft.ServiceFabric.Data.BackupInfo, System.Threading.CancellationToken, System.Threading.Tasks.Task<bool>> -> System.Threading.Tasks.Task

Function BackupAsync (option As BackupOption, timeout As TimeSpan, cancellationToken As CancellationToken, backupCallback As Func(Of BackupInfo, CancellationToken, Task(Of Boolean))) As Task Implements IStateProviderReplica.BackupAsync

Parameters

option

BackupOption

The option for the backup.

timeout

TimeSpan

The timeout for the backup.

cancellationToken

CancellationToken

The cancellation token for the backup.

backupCallback

Func<BackupInfo,CancellationToken,Task<Boolean>>

The callback to be called once the backup folder is ready.

Returns

Task
