Configuring snapshot transfer management
Configuring a snapshot transfer:
NOTE: At the end of the Snapshot Transfer Setup Wizard, the initial data transfer is run from source to destination. After the data is transferred, a snapshot is created. Each subsequent transfer that is run will do two things: 1) Any missing data (the differential) will be transferred from the source to the destination so that both have the same data. 2) After the data transfer is complete, a snapshot is created to record the state of the data at that point in time.
DS-Client must be configured to connect to each Storage that will be used for snapshot transfer. The following steps assume that the Storage device(s) are running and can be accessed by DS-Client.
1. On the Snapshot Manager menu, click Snapshot Transfer.
The Snapshot Transfer Manager dialog box appears.
2. To add a new Snapshot Transfer configuration, click Snapshot Transfer Setup.
3. In the Select Source Storage page, select the source storage from which the volume data will be read, and then click Next.
4. In the Select Volume/qtree page, select the volume/qtree on the source Storage that will be protected, and then click Next.
NOTE: Although all existing volume/qtrees appear in this list, you cannot select a replicated qtree or volume containing a replicated qtree as the source.
5. In the Select Destination Storage page, select the destination Storage, where the data will be copied, and then click Next.
6. In the Select Volume page, select the volume on the destination Storage where the data will be copied, and then click Next.
NOTE: If you create a new snapshot transfer on a destination volume where a Retention Policy is already defined, the Select Snapshot Retention dialog box will not appear. This dialog box appears only for the first snapshot transfer created on a destination volume.
7. (Optional) The Select Snapshot Retention page, select a Snapshot Retention Policy for the destination volume, and then click Next.
8. (Optional) In the Select Snapshot Schedule page, select a Snapshot Schedule for the destination volume, and then click Next.
NOTE: If you create a new snapshot transfer on a destination volume where a Retention Policy is already defined, this dialog box will not appear. This dialog box appears only for the first snapshot transfer created on a destination volume.
9. In the Specify Snapshot Transfer Setup Name page, type a name for this configuration, and (optionally) a Bandwidth Throttle and a Description.
10. Click Finish.
The initial transfer from source to destination is triggered immediately after the snapshot transfer is created.
