HOW POLICY STORAGE IS RELATED TO DATA DOMAIN ?

HOW POLICY STORAGE IS RELATED TO DATA DOMAIN ?

  • Yes, that is correct. You define multiple Stu the first OS for the backup, usually to disk, the others (you can have multiple ) are for the duplications. With slp, your backup is given a retention like normal, but until the duplications are made the backup has a retention of infinity, this is to be sure the backup does not expire, before the copies are made. The manuals explain it clearly (admin guide). Martin

  • I am unsure why you are taling about DataDomain if you question is really :

    "when we write slp name in policy storage tab,what does that mean?"

    Have you checked the manuals, we keep asking you to do this, buit for some reason you refuse.

    The Policy storage is the 'location' the data is stored for that policy.  For the most simple setup, this will be a Storage Unit.

    If a SLP is listed in the Policy Storage, then quite clearly, this means the data is sent to the SLP.

  • SLP contains storage units.

    You define SLP to (for example) backup to the 'first' storage unit, and then duplicate to the 'second' storage unit.

    This is all covered in the NetBackup Admin guide.

  • so each slp contains a storage unit?

    when we create a slp,we define the storage unit for first and duplicate storage unit?

  • As the other excellent post have said - a SLP is exactly what its name implies - a Storage Lifecycle Policy

    It determines what will happen with a backup, its duplication(s) and how long they will be kept for

    So, as you have said you have a SLP that defines the storage unit used for the backup and the retention of that backup. It also then, usually, goes on to define the storage unit used for a duplicate copy of the backup and that copies retention,

    So, to answer your initial question, when you select the SLP in the policy attributes section you define where the initial backup will go, how long it will be retained for and where it will be duplicated to as well as how long that duplicate copy wil be retained for.

    The actual duplication process of the initial backup is totaly automatic and needs no intervention from yourself

    Hope this clarifies things for you
