Repopulating the client file index by using the nsrck program

Use the nsrck program to repopulate the client file index with information about all save sets for the client up to the date and time specified.

1. Ensure that the volume containing the index backup is available.
2. Use the nsrck command to repopulate the client file index:
   nsrck -L 7 -t MM/DD/YYYY client_name

   where:

   • where client_name is the name of the client with the data to be recovered.

   • MM/DD/YYYY is the backup date of the save set.

   For example:

   <NetWorker_install_path>\nsr\bin>nsrck -L 7 -t "11/21/2009" swift nsrck: checking index for 'swift' 9343:nsrck: The file index for client 'swift' will be recovered.Requesting 1 rec over session(s) from server Recover completion time: 11/20/2009 1:45:55 PM nsrck: <NetWorker_install_path>\nsr\index\swift contains 12 records occupying 2 KB nsrck: Completed checking 1 client(s)

   When you recover a client file index from a time and date in the past, nsrck adds the full contents of the index from that time and date to a temporary subdirectory of the client file index directory. When a time value is not specified, everything for the specified date (up to 23:59) is included. After the index has been read from the backup media, the required index data is integrated fully into the client file indexes and the temporary subdirectory is removed. The “required index data” includes the indexes from the date specified to the first full backup that occurred prior to the date specified.

   Be aware that if a save set from the specified date runs into the next day, which would be Nov 22, 2009 in this example, then the index required to browse the save set will not be recovered. To recover this index, you would have to specify Nov 22, 2009 as the recovery date as shown in the following command:

   nsrck -t "11/22/2009" -L7 swift

   A check on the required index date may be necessary if index backups are set to be taken once daily. When the back up of the index does not take place until the following day, the date of the following day must be specified.

3. Confirm that the client save sets are now browsable:

   mminfo -q ssid=ssid -r sumflags

   Browsable save sets contain a b, in addition to other values in the sumflags output.

   For example:

   NetWorker_install_path\nsr\bin>mminfo -q ssid=4294078835 -r sumflags
   cb

4. Perform a file-by-file recovery by using the NetWorker User program (Windows), the recover command or the NMC Recovery Wizard.
