Restoring Data from a DR Series System Using Backup Exec
This topic describes how to use Backup Exec to restore data from a DR Series system.
To restore data from a DR Series system using Backup Exec, complete the following:
1. Launch the Backup Exec Administrator console, and select the Job Setup tab.
2. In the left navigation pane, select Restore Tasks, and click New job.
The Restore Job Properties page is displayed.
3. Click the View by Resource tab in the Selections pane, and select the dataset to be restored.
4. Click Run Now to start the restore job.
5. Click the Job Monitor tab to view the progress of the restore job operation you created.
Understanding the OST CLI Commands
The --mode component supported in the DR Series system command line interface (CLI) command supports three
values, which represent optimized writes done via:
• deduplication (--mode dedupe) The client will process hashing on data, so deduplication processing occurs on the
server side (client-side deduplication).
• passthrough (--mode passthrough) The client will pass all data to DR for deduplication processing (appliance-side
deduplication).
• auto (--mode auto)
DR will set the deduplication to Dedupe or Passthrough, based on the client’s number of cores and whether it is 32–
or 64–bit.
These OST commands are used in the following format: ost --update_client --name --mode.
NOTE: If a RDA with OST client has four or more CPU cores, it is considered to be dedupe-capable. However, the
client operating mode depends upon how it is configured in the DR Series system (Dedupe is the default RDA with
OST client mode). If the administrator did not configure a client to operate in a specific mode and it is dedupe-
capable, it will run in the Dedupe mode. If a client is not dedupe-capable (meaning the client has less than four
CPU cores), and the administrator sets it to run in the Dedupe mode, it will only run in the Passthrough mode. If a
client is set to run in Auto mode, the client will run in the mode setting determined by the media server. The
following table shows the relationship between the configured client mode types and the supported client mode
based on client architecture type and corresponding number of CPU cores.
Table 7. Supported RDA with OST Client Modes and Settings
Client Mode Settings 32–Bit Client (4 or
more CPU cores)
64–Bit Client (4 or
more CPU cores) 32–Bit Client (Less
than 4 CPU cores) 64–Bit Client (Less
than 4 CPU cores)
Auto Passthrough Dedupe Passthrough Passthrough
Dedupe Not Supported Supported Not Supported Not Supported
Passthrough Supported Supported Supported Supported
