change image retention from 28 days to 7 years on backed up image

I have backed up a large file server which takes 5 days to backup using the Storage Lifecycle policy with weekly retention where it backups to VTL and then copied off to the tape for offsite. As such the retention is 28 days. Is it possible to extend the retention on the physical tape to 7 years. I do not want to rerun the backup for this 7 yr rentention as it takes long time to backup.

I would like to have the VTL image expired in 28 days and keep it on the tape for 7 yrs. Would it be better to have image copied to physical tape first and than use bpexpdate or is there way it can write to physical tape from vtl with new retention.

    You can use bpexpdate to change the retention of backups already duplicated to tape.

    You can change the retention level in the SLP for the duplicate copy going to tape STU. Leave the backup to VTL with 28 day retention.

    That is the whole idea with Storage Life Cycle Policies - to accommodate different retention needs on different storage types.

    I assume that you have customized a retention level for 7 years using Host Properties?

    use the below command to extend the retention of a backup image

    install_path\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,...]

     

    example: if your tape image is copy 1 and need to extend from todays date to 7 years then fallow the below command

     

     install_path\NetBackup\bin\admincmd\bpexpdate -recalculate [-backupid backup_id] -copy 1 -d 1/14/2018

     

    If you are using SLP then SLP will take care of the retention. You can configure different retention level to VTL meadia and as well as Tape.

    Sorry was out of office so couldn't check the posts. Thanks for the replies. What is easier way to find what physical tapes have the image. Since its already written within slp to tapes with 28 days retention, I would like to extend it to yearly rentention on the physical tapes.

    Use the following command to find the list of tapes used by a policy

    bpimagelist -policy POLICY_NAME -d 01/18/2011 -e 01/18/2011 -l | grep -i frag | awk '{print $9}'

    This would list the media used by the policy during 18 Jan 2011.

    Use this list and run the following loop.

    for i in `cat file_name`

    do

    bpexpdate -m $i -d [retention end date]

    done

    You can use the -media switch with bpimagelist to get the media-ids:

    bpimagelist -d mm/dd/yyyy -e mm/dd/yyyy –media

    Then use bpexdate to change expiration of each media-id.

    You can set customized retentions under Host properties -> master server -> properties -> retention levels. Just edit any of infinity retention levels to 7 years.

    Also you can modify your SLP to duplicate the images with 7 years retention for tapes. SO this will make sure all your future backups having 7 yrs retention.
