Determine time backups kept on Disk

I have a small environment with a disc array and a tape drive.  It seems as if the backups are not going to disk before tape.  I think the disc is continually getting full.  Is there a way to determine how long a backup is being stored on Disc before it moves to tape?

 

Thanks,

 

Mike

    No option to tell if  the disk stu contain 7 days directly. 

    A DSSU will keep so many backup images on disc as space allow. Once the disk is full it will delete the oldest backup images already staged to tape (this is what high and low watermark is used for). More details in the tech notes Marianne and I referred earlier. 

    if you want to retain more days on disk either reduce load or increase disk space.

    Find the the oldes files in the F:\bkp1-arraybackup and convert the epoch epoch time to human time by

    # bpdbm -ctime 1166000000

    Hi Mike 

    What type of disk storage unit have you configured ?

    Can you do a bpstulist -L or take a screen dump from the storage unit configuration ?

    Since you have a small environment I would guess you have a DSSU storage unit. Symantec has released a tech note describing the behavior of the DSSU

    http://www.symantec.com/docs/TECH44719

    Please review it and tell us if it apply.

    Thanks,

     

    I think I found the problem, looks like our tape drive had a tape stuck which stopped all writing to tape.  I'm new too NetBackup and just want to ensure that I have a backup on disk for at least 7 days.  We have really old environment that requires the use of BMR often.  Here is the dump of the stulist.

    Thanks,

     

    I think I might have found the problem of it filling up, tape drive wasnt functioning properly.  I work in a very old AIX environment and we have to perform BMR's often, It would be helpful to know how long images are on disc before moving to tape.  Is this possible?
