Netbackup - Storage Lifecycle policies

Ok we are setting up a new netbackup environment:

Netbackup 6.5.6

1 master server

2 media servers

9 TB of disk attached to each media server

1 tape library, with 2 drives

2 Storage units setup already (9TB of disk in each) 1 per Media server (advanced disk)

1 storage group containing the 2 stoarge units.

 

We want to basically do all backups to the disk and the copy to tape everyday.

We are going to use storage lifecycle policies.

I am getting a bit confused with retention periods, if we set retention periods on the backup policies does that get overwritten by the retention on the storage policies. Do we just use the duplication option and choose "expire after duplication"? And how does data classification come into it?

Also if we want to keep the data from specific server or policy on the disk for 1 week, how do we go about setting that up?

 

All help welcome

  • If your going to do just a windows file system backup then that is correct.

    you must create the SLP and it is classed as a storage unit and comes under the policy storage dropdown of the attributes tab

  • Hi,

    Do you have the an advanced disk option for this as your require this to use SLP's with disk.

    If you do all you need to do is create and a new SLP. Within that create a backup task an to stay on the diskd point it to your disk storage units. Then set a fixed retention period of how long you want that data to stay on the disk for. in your case 1 week. Then create a duplication job to one of your tape libraries setting the retention period of how long you want to keep the backup for ie 1 year.

    In this senario the back will go to disk first and be kept on there for 1 week. the backup will be duplicated to tape and kept for 1 year.

    In your case you do not want to set the expire after duplication as you want the data to stay on the disk for 1 week. If you did select that option say the backup was taken friday morning and duplicated to tape friday afternoon, the backup would be removed after the duplication and you would not have your backup on disk for 1 week.

    SLP's set the retention period for the backups not the policies. If you look the retention period in the policies after you select the policy to use an SLP, theretention periods grey out to specify they are not in use.

    Data classification is used to specify how critical the data is. Platinum is the highest and netbackup will try and keep that data for longer on your disk units if you dont use fixed retention periods over bronze etc.

     

    I hope this helps answer your questions!

  • I am create a MS-Windows-NT type backup policy should this be some other type?

    I don't see any options to use an SLP on the attributes tab of the policy?

  • If your going to do just a windows file system backup then that is correct.

    you must create the SLP and it is classed as a storage unit and comes under the policy storage dropdown of the attributes tab

  • ok spot on, right have that and see the retention period greyed out. Perfect thank you.

    Now: How do we set different retention for different types of backups (full, diff, etc) on the one backup policy if we use the same SLP for the 1 policy? Do we need to create different backup policy for each type of backups?

  • You override storage unit selection and point each retention (weekly,daily,monthly)  to diffrent SLP's. No need to create diffrent backup policy. In general my storage unit selection for the policy is always set to "Any" - I then override each schedule to is own SLP.

     

    Schedule list

  • ok, that makes sense so multiple SLP's for each type of backup.

    Starting to sink in now.

     

    Thank you so much for your time
