Hi All, First of all Thanks to Marcelino Mata / Wade Lich / Fernando Boveda for all their inputs. I am putting their fwded mails in this summary below. ***************************************************************************************** From: "Marcelino Mata" <mmata@multimatic.com> Add to Address Book To: "'Sumeet Chandwani'" <sumeetpchandwani@yahoo.com> CC: k.mohan@vsnl.co.in Subject: RE: Using tar to restore files backup up using Veritas Netbackup Date: Fri, 29 Oct 2004 14:14:44 -0400 The file format is not a simple tar listing. It is rather complex system... If the data is expired, you do not need to restore the old catalog from the catalog tape. You should be able to import the catalog data from the tape that holds the data and it will add the policy used for that tape etc. Once you import the catalog data, you can select the files with Netbackup client softwre. I did the step below many years ago and it was painless procedure. I have a Netbackup FAQ which I used for this step....paths are Windows so substite Solaris versions... Q : How do I import expired data. A : Use bpimport, See Netbackup help page for more information The import operation consists of two steps: Step 1 is performed with the first form of the command shown above (-create_db_info option) and recreates catalog entries for the backups that are on the specified media. Step 2 is performed with the second form of the command shown above and imports the backups from the media. The expiration date for imported backups is the current date plus the retention period. For example, if a backup is imported on 11/14/98 and its retention level is one week, its new expiration date is 11/21/98. You can import a backup only if all copies of it are expired. For more information on importing backups, see your NetBackup system administrator's guide. Step 1 command install_path\NetBackup\admincmd\bin\bpimport -create_db_info -id media_id [-L output_file] (-L option does not seem to work) This command only list backup image names not files on tape. Listing images on tape bpimport -s [start date] -e [end date] i.e bpimport -s 11/01/98 -e 11/10/98 List data to import without importing : bpimport -PM -s 11/01/98 -e 11/10/98 Sample output : 07/17/20000 15:31:47 Archive Full_Archive aixserver_0963862307 mtc_mis ARCH01 Importing all images on tape from step 1 bpimport -v -id 000176 ***************************************************************************************** From: "Wade Lich" <wade@nerdfest.com> Add to Address Book To: "'Sumeet Chandwani'" <sumeetpchandwani@yahoo.com> Subject: RE: Using tar to restore files backup up using Veritas Netbackup Date: Fri, 29 Oct 2004 10:25:26 -0700 mt -f /dev/rmt/1 rew /usr/netbackup/bin/tar -tf /dev/rmt/1n If that doesn't produce anything try mt -f /dev/rmt/1 rew mt -f /dev/rmt/1n fsf 1 /usr/netbackup/bin/tar -tf /dev/rmt/1n Increment the fsf # by one until you find a good tar file on the tape. chances are good that the first file on the tape is not the beginning of the archive set and you may need to skip around until you find a file that is the actual beginning of the backup file.

We are trying to restore the backup on the tape using the tar in the netbackup/bin folder and getting the following error "Hm.. This does not seem to be a tar file". Has anybody dealt with such kind of problem earlier or know or think they know its solution ? Has anyone restored the old catalogs from catalog backups and then restored the expired images from that ? We are definately sure that the tape has not been overwritten. If anyone knows anything please reply me and cc to k.mohan@vsnl.co.in Thanks & Best Regards Sumeet. Yahoo! Mail Address AutoComplete - You start. We finish. Tired of spam? Yahoo!
