    Check your PG configuration and see if tape co-location option will help with tape usage.

    If Protection groups do not have the same retension period, and if you have not enabled tape co-location, DPM will require seperate tapes for the PG's.

     

    Please see this technet article: http://technet.microsoft.com/en-us/library/cc964296.aspx

    Command to enable co-location of data on tape on the DPM Powershell window: 

               Set-DPMGlobalProperty -DpmServer <DPM Server Name> -OptimizeTapeUsage $true

     

    Restrictions

    The following restrictions apply to using data co-location in DPM:

    • You cannot apply co-location selectively. If enabled, it applies to all protection groups.
    • Only protection groups with the same retention period can be co-located on the same tape.
    • Encrypted and non-encrypted datasets cannot be co-located on the same tape.
    • Datasets from different vaults cannot be co-located on the same tape.
    • Protection groups configured for “Full and Incremental” cannot be co-located with those configured for “Full Backup Only”.

     

    For the no free tape, During a tape backup if a tape becomes full, DPM will raise an alert to prompt for another free tape to continue backup. It will wait for 1 hour by default before failing the job.

    This prompting timeout can be configured by the registry entry “PromptingTimeOut” under “HKLM\Software\Microsoft\Microsoft Data Protection Manager\1.0\Prompting”

    PromptingTimeOut:REG_Dword:43200000  (decimal) = 12hrs

    The Formula is   (#hrs * 1000 * 60 * 60)

    1HR =  1*1000*60*60 =  3600000  decimal


    So for each hour to wait, multiply by 3600000.

    8hrs = 28800000  decimal

  • Can you check if you have a free tape available in you tape library on which DPM can take a backup? 

     

    thanks,

  • So, why can't the error state something understandable like: "Current tape is full. Please insert blank tape."

  • Hi,

    The alert does state that another free tape is required, please modify the registry key to give yourself time to change the tape and not fail the backup job.

    During a tape backup if a tape becomes full, DPM will raise an alert to prompt for another free tape to continue backup. It will wait for 1 hour by default before failing the job.

    This prompting timeout can be configured by the registry entry “PromptingTimeOut” under “HKLM\Software\Microsoft\Microsoft Data Protection Manager\1.0\Prompting”

    PromptingTimeOut:REG_Dword:43200000  (decimal) = 12hrs

    The Formula is   (#hrs * 1000 * 60 * 60)

    1HR =  1*1000*60*60 =  3600000  decimal

  • Hi,

    maybe it is no longer active but i will give a shot..

    I have the same problem.. Enabled colocation, same retention period for PG's.. and after 600 GB it says that tape is full but it is not considering that tape has 1.5 TB of space..

    Do you maybe have some advice?

    Tnx

    B.
