Restoring a backup from one month ago

 

Hello, I am kinda new to this topic. I have been running backups for awhile now, but face a new issue. We have five magazines of tapes -- each magazine is a week. I want to restore a NetBackup 7.0 full backup from one month ago, but all NetBackup shows in the Restore window is last week's backup. How do I display, say 8/25/12 and restore its backup? I have the magazine from one week ago. Will the tapes be overwritten this week since the magazine is repeated?
 
I've read a few forum posts, but don't know what these commands do:
  /usr/openv/netbackup/bin/admincmd/bpexpdate -recalculate [-backupid backup_id]   [-copy number] -d date |0|infinity][-client name] [-policy name] [-ret retention_level] [-sched type] [-M master_server[,...,]]
  
With best regards,

    Check the default application schedule retention - this is the one that sets the retention period and not the one you vreate that governs when the backup actually runs

    For this type of backup you usually need Daily, Weekly and Monthly policies so that each one gets a suitable retention period in the application schedule

    I am guessing that this is the case and you will need to import the tapes (phase1 and phase 2) as outlines above before you will be able to do a restore

    Do you have access to the Netbackup GUI? If so use the Backup, Archive and Restore section and restore your files. You can set a date range in there.

    Yes, but the date range of, say, 8/1/12 -- 9/25/12 doesn't find anything but last week (which isn't on the magazine that is in).

    Thanks

    Are you selecting the correct Policy Type in the restore selection.

    If you are and you are selecting the correct client and date  NetBackup may not have anything for the date you are specifying. The backup may have expired.

    If a tape or backupid is expired, there is no way to unexpire it. You could potentially recover it from a catalog backup, but if the tape has been reused, it's gone forever.

    What type of backup is this? (file system / database etc.)

    Are you sure that the retention period set initially was correct?

    Go to the catalog section of the Admin console and search for  that clients backups in the date range you are looking for - if nothing is there then they have expired and you will need to import all of the images from the tapes you have (otehrwise they will get overwrittne if you put those tapes back into the tape library

    Let us know what you find

    The backup type is database -- I want to restore 8/25/12 (a census date) for reporting purposes before it is overwritten (this week). I can pull the tape for 8/25/12 (#6 (I think) - Saturday).

    The retention period is probably set to default -- my supervisor has retired.

    The search in the Catalog did not find anything for 8/25/12 (just last week). 

    Thank you, with regards,
