Confirming backup Finish Times for for Protection Groups RRS feed

  • Question

  • Hi, as a relative newcomer to DPM 2010, I cannot find a location in either the admin console or logs which confirms the times that various (DAS & TAPE) protecion groups complete their backups ?

  • Hi,

    Under the Monitoring tab, go to the JOBS tab.  On the right side there is a link to "create custom filter" - click on that, and from there you can select the type of jobs to filter, the time period, and the specific protection groups or individuial data sources.  You can get very granular and look at all jobs for a particular data source on a specific protected machine for a specific time period (max 30 day window).  You can order it by status, or I like the by Computer option, then you can see all activity (jobs) that ran, their start / finish tiumes, and amount of data transfered for that computer.

  • Excellent Answer, thank you very much. So effectively there's no concern as to the allowed time for a D2D backup to complete, in terms of when to schedule the tape back up to start because the D2D recovery point should run and complete in seconds as it's effectectively an accumulation of the incremental synchronisations throughout the day ?

  • Hi,

    You should take a look at "monitoring" tab and search for column "time elapsed"

    Stéphane.

  • Thanks very much for the prompt reply Mike, am I right in assuming that none of the filters available allows me to see how the finish off the backup to DAS ? I cannot see an option under the jobs tab (tape backup, Recovery Point etc) , which menations Disk backup ?

  • Hi,

    "Recovery point" is DASD Disk based backup.
    "Tape backup" is tape backup.

  • Thanks Mike,

    when I select the "Recovery Point" option, the details are not "accurately displayed" for the DAS backup. The start time of 18:00 is correct but the duration is seconds and the amount backed up is O MB (when the figure should be over 1 TB)

  • Hi,

    A recovery point does not move data, it simply creates a VSS snapshot of the replica volume which makes the data accessible under the recovery tab.  If you want to see how much data was transfered to the DPM server between recovery points, you need to include synchronization jobs.

  • That's very interesting, so when I show the "synchronisation" jobs, I can see data transferred but it only amounts to 1.5 GB, (cumulative total from various synchronisations throughtout the day). Are you saying that, at the scheduled time for the recovery point (in our case 18:00), that it marks the data as available for backup but that the actual transfer of data to the DAS occurs at various intervals throught the day and that the data backed up is effectively an incremental backup  rather than the full backup that is transferred to the tape every day ?

  • Hi,

    Not exactly correct, but close.

    I assume were talking Short term Disk and long term Tape (D2D2T) protection.

    For D2D, DPM performs synchronization jobs based on your schedule.  Lets say hourly.  Every Hour, DPM contacts the proteced server and transfers changed blocks and applies them to the replica disk on the DPM Server.  In between synchronizations, the DPMFilter on the protected server keeps track of new changed blocks, so the next Synchronization that runs will only tranfser those changed blocks to DPM.   None of those synchronizations are available for restorations, it's only after a scheduled recovery point runs that the recovery point is exposed under the recovery tab.  The data is already on the DPM server, the recovery point job only exposes it as a recovery point that is restorable. 

    Fast forward to a scheduled tape backup.  DPM mounts the latest recovery point and writes the entire contents to tape.  ALL long term tape backups are FULL backups of the latest data from the last disk based recovery point. 

    If you go to the restore tab, you will note that the backup date\time is the SAME for both a disk and tape restore regardless of when the tape job actually ran.  This is because the data on disk and the data on tape are identical for that recovery points time.
