Save set recover from the command prompt

Save set recover:

The save set selection recovery method, or save set recover enables you to recover data without browsing and selecting the files for recovery. Unlike a browsable recovery, a save set recover does not inspect the client file index for information about each selected file. 


When you perform a save set recovery, NetWorker recovers the last full backup first, then recovers incremental backups in the chronological backup order. 

Use a save set recovery in the following scenarios:


• To recover many files or all the data in a save set, for example, if there is a total disk failure. When you perform a save set recovery, you do not select   individual files or directories for recovery.

• To recover data from a recyclable save set. 

• To recover data on a host with limited memory resources. A save set recovery requires less memory than a browsable recovery.




1. Connect to the target host with the root account on UNIX or the Administrator on Windows.

2. Use the mminfo command to display information about the save set of the data that you want to recover.

For example, type: mminfo -av -r volume,savetime,client,ssid,cloneid,name

Output similar to the following appears:

volume            date                 client                 ssid              clone      id name
backup.001 05/03/2015  bu_iddnwserver 3644194209 1362492833  C:\ddlib
clone.001   05/03/2015   bu_iddnwserver 3644194209 1362493448  C:\ddlib

To recover the all the data from a backup save set, type the following command:

recover -S ssid - i_recover_option

where:

-S ssid is the SSID of the backup save set.

-i_recover_option

• iN does not recover the file when a conflict occurs.
• iY overwrites the existing file when a conflict occurs.
• iR renames the file when a conflict occurs. The recover process appends a .R to each recovered file name.


recover -S 3644194209 -iR

To recover the all the data from a clone save set, type the following command:

recover -S ssid/cloneid

*ssid is the SSID of the backup save set.

*clonied is the cloneid of the clone save set.

recover -S 3644194209/1362493448

To recover a single directory from the clone save set and relocate the data to a new directory location, type the following command:

recover -S ssid/cloneid -d destination_dir original_dir


Example : Performing a recover in interactive mode

1. Type: recover

2. To select the files or directories to recover:

a. Specify the directory to browse, for example:

recover> cd /var/adm

b. Select the file or directory for recovery:

recover> add file_name

3. To view the selected files or directory:

recover> list

4. To view the list of the volumes that NetWorker requires to recover the data:

recover> volumes

5. To recover the files to a location that differs from the original location, type:

recover> relocate path

6. To start the recovery operation, type:

recover> recover

7. When the recovery process completes, messages similar to the following appear:

Received 1 file(s) from NSR server `jupiter'

Recover completion time: Tue Jan 21 08:33:04 2009

recover>

8. To close the recover program, type Quit.


Example: Performing a recover in non-interactive mode:
To recover a directory /testdir on client mar

To recover a directory /testdir on client mars to a new directory /newdir on client mars, type:

recover -d /newdir -a /testdir


Example: Save set recover from command line


To recover a directory /testdir from a save set with a ssid of 12345678 and overwrite any existing files with the same name, type this command:

recover -S 12345678 -iY /testdir

Example: Performing a directed recover

To recover a directory c:\mydir that was backed up on client mars to client jupiter, type:


1. On client mars, type:

recover -R jupiter -iY

2. Add the c:\mydir directory:

recover> add c:\mydir

3. Recover the files:

recover> recover

Also check below commands:

recover -a -s NetWorker_servername -c source_host -S ssid/cloneid -d destination_directory -R destination_host -i_recover_option [directory_name]

-a used to perform the recovery in non-interactive mode. You cannot use the -a option with the -R option. You cannot use the -a option to restore 
 Windows SYSTEM or VSS save sets.

-s NetWorker_servername specifies the name of the source client’s NetWorker server.

-c source_host—Specifies the source host.

-S ssid/cloneid used to perform a save set recover.

-d destination_directory

- i_recover_option

• iN does not recover the file when a conflict occurs.
• iY overwrites the existing file when a conflict occurs.
• iR renames the file when a conflict occurs. The recover process appends a .R to each recovered file name.

◆ source_directory—Specifies the initial directory in which to begin browsing.
