Backup to Disk To Tape

Hi, we are running NetBackup 7.7.3. 

We are currently backing up specific servers to disk, so that the backup is faster, and then sending it to tape. But we are getting errors from time to time where we do not have enough space available on the disk. Looks like the disk is not getting copied to tape or that it's not getting erased.

Is there a way to have the backup to was made on disk to be sent to tape as soon as it's done?

  • What type of Disk Storage Unit have you configured? Can we assume Basic Disk?

    With Basic Disk, you cannot use SLPs. You can only create staging schedule(s) to run duplications a number of times per day (every xx hours). Disk space will only be cleaned up if images have been successfully duplicated and high water mark is reached.

    Can you tell us what high and low water marks you have specified in STU config?

    Best to provide sufficient space to hold at least 2 full backups on disk.

    If you have configured Advanced Disk or MSDP, then please let us know.

      Hi Marianne,

      You are correct, we are using Basic Disk. We have a staging schedule configured, I guess incorrectly. The High water mark is set to 50% and low water mark to 10% right now.

      There's the issue, we are not able to give enough space to hold 2 full backups, only 1. That's why I want to send the data to tape as soon as possible when the backup to disk is complete.

      What would be the best configuration with Basic Disk?

       

      I will take a look at the Admin guide also, thanks.

        Think about your config - you don't have big enough storage, and then you config HWM as 50%?
        The other 50% cannot be used and is therefore wasted.

        The default is 98%.
        Why not stick with that?
  • Hi,

    Can you check NetBackup Administrator's Guide,Volume I. If you want only sent backup made on disk to as soon as its done, you can you Storage Lifecylce Policies ( SLP).

    If you want to only erase the disk after backup to dis was done, I belive that you can create a Vault. Take a look this document.

    Regards,
