Working With Received VTL Partition Snapshots

Note:目标系统将保留10复制snapshots (default setting) for each replicated partition. When 10 snapshots have been saved, the oldest snapshot is deleted to make room for each new snapshot that is received. For instructions to change the maximum number of snapshots retained for each partition, see管理复制源.

1. From the复制page, clickReceive > VTL > Received Snapshotsto display theSnapshots List.

   Figure 1:Snapshots List

   

2. Review the following information about received snapshots:
   Navigation Information

   • Snapshots are grouped by VTL partition.
   • To see all available snapshots for a partition, click the plus icon[+]next to the partition name.
   • Click a column heading to sort the rows in the table by that column. Click the column heading again to reverse the sort order.

   Column	描述
   Partition Name	这name of the partition.
   Source System	这hostname of the system from which the snapshot was sent.
   Started	最近的复制作业启动的时间。
   完成的	这time the most recent replication job finished.
   Status	最新复制作业的状态。Click the status to display detailed information about the most recent replication job. 有关更多信息，请参阅最新复制作业的状态。看最新复制作业的状态。看复制and Synchronization Status.

恢复VTL分区如果源系统不可用，则需要访问分区，例如当您需要继续执行备份时。恢复分区时，您选择收到的快照。这Q云保护appliance uses the snapshot to recreate the partition just as it was at the point in time when the snapshot was saved.

恢复配置说明和注意事项

查看以下信息以正确配置恢复的分区。

Partition Requirements

To recover a partition, the target system must support the library emulation and drive type used in the original partition. For a list of the available library emulations and drive types on the target system, seeManaging VTL Partitions.

恢复分区后，必须将磁带驱动器添加到分区。磁带驱动类型必须与原始分区相同，以便介质兼容。此外，您必须在访问VTL分区之前映射设备。

If the partition contains media, you will only be able to select the highest capacity tape drive for that media type.

Example

如果分区包含SDLT600磁带盒，则在将设备映射到恢复的分区时，您只能选择DLT-S4磁带驱动器。

VTL Partitions on the Cloud Appliance

When a VTL partition is recovered on a target system, a new serial number is created for the partition.

在目标上恢复分区后，如果要继续将数据备份到该分区，则必须重新映射备份应用程序以指向目标系统。

Recover a partition

1. From the复制page, clickReceive > VTL > Received Snapshotsto display theSnapshots List.
2. Select a snapshot and clickRecoverto display theRecovered Partition Name页。

   Figure 2:恢复的分区名称页面

   

3. (Optional) In theRecovered Partition Name框，键入恢复分区的新名称。

   默认名称是原始分区名称。

4. ClickApplyto recover the partition and its cartridges on the target system.

   All data stored on the partition at the time the snapshot was saved is available.

Perform a failback of a VTL partition if a source system that was previously unavailable becomes available again.

在故障恢复分区时，您可以在云设备上选择收到的快照。云设备将快照复制回源系统。然后，您可以执行RECOVER操作以在源系统上重新创建分区，就像保存快照时的时间点一样。

先决条件和发布的考虑因素

Review the following information to correctly configure the systems for failback.

前提

Before you can failback a partition, you must add the original target system to the list of allowed replication sources on the original source system. During failback, the original target is acting as a source when it sends a snapshot to the original source.

For detailed instructions, see管理复制源.

邮寄故障返还

恢复分区后，必须将磁带驱动器和机器人添加到分区。您还必须在访问VTL分区之前映射设备。

If the partition contains media, you will only be able to select the highest capacity tape drive for that media type.

Example

如果分区包含SDLT600磁带盒，则在将设备映射到恢复的分区时，您只能选择DLT-S4磁带驱动器。

VTL Partitions on the Cloud Appliance

When a VTL partition is recovered on a target system, a new serial number is created for the partition.

If you previously remapped your backup application to a recovered partition on the target system, you must remap your backup application again to point to the source system after you failback the partition.

Perform a failback

1. From the复制page, clickReceive > VTL > Failback Snapshotsto display theSnapshots List.

2. 在里面Snapshots List, select a snapshot and click故障回复to display the故障回复目标页。

3. (Optional) In the故障回复Destination System框，键入故障恢复分区的目标系统的主机名或IP地址。

   这default destination is the original source system.

4. （可选）离开Use Encryptioncheck box selected to enable encryption when sending the snapshot to the destination.

   警告：如果您在DXI 2.1软件之前将数据发送到运行软件版本的DXI系统，请选择128位加密。

5. ClickApplyto send the snapshot to the source system.

6. On the source system'sSnapshots List, select the snapshot that was sent during the failback operation and clickRecoverto display theRecovered Share Name页。

7. (Optional) In theRecovered Partition Name框，键入恢复分区的新名称。

   默认名称是原始分区名称。

8. ClickApply在源系统上恢复分区及其墨盒。

   All data stored on the partition at the time the snapshot was saved is available.

如果不再需要，请删除快照。请记住，删除快照后，它无法再用于恢复或故障恢复VTL分区。

Note:如果对快照进行故障回复操作，则无法删除快照。等待故障回复操作完成，或中止操作。看查看分区的故障恢复作业状态.

删除快照

1. Do one of the following actions:

   • On the source system, disable replication for the partition associated with the snapshot. See启用共享或分区的复制.
   • 在目标系统上，从允许的复制源列表中删除与快照关联的源系统。看管理复制源.

2. On the target system'sSnapshots List, select a snapshot and click删除.

   Note:If you delete the last snapshot for a partition while replication for the partition to this target is still enabled, any replicated data not yet protected by a replicated partition isnotdeleted. To delete this data, disable replication for the partition on the source system before deleting the last snapshot.

3. ClickYesto confirm the action.
