Issue with Bootstrap information in Networker 7.4.4

Hemant-I97jT
Hello,
     We are using Networker 7.4.4 in Windows 2008 32 environment.
We have scheduled as well as manual backup (running manually using the save command)
The problem is releated to disaster recovery.
Case 1:
if disaster recovery is performed after last scheduled backup backup. We are able to
recover the bootstrap information using scanner command (scanner -B \\.\Tape0)
Case 2:
if disaster recovery is performed after maunal save command. We are not able to retrieve
recover the bootstrap information using scanner command (scanner -B \\.\Tape0).
E:\nsr\bin>scanner -B \\.\Tape0
8909:scanner: using '\\.\Tape0' as the device name
8936:scanner: scanning LTO Ultrium-3 tape CFBRACBRFiles.007 on \\.\Tape0
8761:scanner: done with LTO Ultrium-3 tape CFBRACBRFiles.007
8918:scanner: No bootstrap located
As i read in Networker administrator manual that during manual save command, the bootstrap information will not generated.
In this case how to recover bootstrap information.
Regards
Hemant

    Hi Hemant,

     

    Yes, Bootstrap will not be generated when a manual backup is kicked off.

     

    Is the Both schedule & manual runs on the same volume (CFBRACBRFiles.007).

     

    Run mminfo -B & this will provide the volume information where the bootstrap's are locted.

    Hello Hari,

                  Thanks for your response.

    The "mminfo -B" will not work as we are doing disaster recovery (we had freshly installed the Networker and trying to get the bootstrap info).

     

    No. schedule and manual backup runs on different volume.

     

     

     

     

    Thanks

    With Regards

    Hemant.

    Hi Hemant,

     

    Is the volume "CFBRACBRFiles.007" belongs to schedule backup pool or manual backup pool.

     

    If it belongs to the manual backup pool , Then You need to run scanner on the schdule backup pool tape to get the information about the bootstrap ( Since the bootstrap will not be generated by adhoc backups ).

    All,

     

    Bootstrap information is required for any DR situation and if the last backup of the NetWorker server is a manual backup this will not secure the information required for DR, as the NetWorker software will be running while you attempted to save the res, media database etc, (even if this were part of the backup) we may not get a consistent copy of the data.  Rather than trying to identify the last tape used by the NetWorker server and scanning this in there are easier and more reliable ways to DR the NetWorker server.  If you for any reason cannot identify volumes which have a bootstrap within them you could end up scanning several (10,100's of volumes) trying to identify the most recent.  Retrieving information from a tape without knowing the position of the backup within the tape is time consuming and could significantly delay the recovery of the server.

     

     

     

    There are two easy ways to record the bootstrap information within an environment: -

     

    1.  Run a special backup where all unique clients are linked to a group, then run savegrp -O  then transfer this file (ftp, scp or similar) to 2 or 3 other servers within the environment, with at least one in a different location.  This can be scheduled from Unix Cron or Windows Scheduler  several times a day and then use this file to identify the volumes you need for the bootstrap and then proceed.  This command gives the last 20 bootstrap backup your NetWorker server has taken with everything you need for the mmrecov command.  You will not have the Client File Indexes as these will most likely be located on many other volumes so it will take slightly longer to recover the historical backup information but you will be able to start new backups of the clients at that point.

    Hello,

     

    Look for the information of the file Bootstrap and daemon.raw savegrp.log.
