has dpm 2012 the same size limit for hyper-v backup? in dpm 2010 it is 18 TB RRS feed

  • has dpm 2012 the same size limit for hyper-v backup? in dpm 2010 it is 18 TB :

     

    A DPM server can back-up up to 18 TB per day. If you exceed this limit, the DPM server may miss the backup SLA. If you go ahead with this protection, you will be backing up 18,5601997375488 TB of Hyper-V data on XXXXXXX. (ID: 32588)

  • As far as backup from Standalone hyper-V is concerned, there should not be anysuch limit in DPM 2012.

    DPM 2012 has the new expressful-Backup feature  for Hyper-V and the backup time  now only depends on the actual data  churn rather than the VM size since we we will read and transfer only the changed blocks during the backup. Hence the reads are reduced  drastically from DPM as well as PS.

  • And what limit is for Hyper-V CSV cluster backups?
    We are planning to backup 30TB to 100TB of data on IBM Storwize V7000 as data source and our old Dell MD3000 as backup target storage, using DPM 2012 with HW VSS writer. We wanted to use "Backup using child partition snapshot" once every day to be able to quickly restore both whole VM and single files.
    Our Storwize reads cca 500MB/s (no other critical bottlenecks), so if we would use this type of backup, DPM will read 30TB of data in about 17,5 hours (30 * 1024 * 1024 / 500 / 3600) and more then 58 hours if we count with 100TB of source data. Another DPM server will not help in our case.

    Is there any recommended scenario for backing up this amount of data in CSVs? And be able to restore both whole VMs and single files within few minutes? Is there a way to back it up using DPM 2012 or should we use other software?

    Thanks in advance for any help,
    Stanislav
