  • Hi,

    I do not know what the roadmap is for Azure backup, but today, your only option for long term protection is tape.

  • Dear Mike,

    DId I fully understood the post 758057.aspx about Backup solutions combining disk and tape on keeping Bk 448 days on disk. ?

  • Hi,

    Today you can make a disk based recovery point one per week for 64 weeks which is 448 days. If you are comfortable with one backup per week, then that could be considered a LT goal.

  • Hey Mike,

    I've got a few questions that are related to long term recovery.

    1. Is there any way to mix daily and monthly recovery points to disk in DPM2012?  What I picture doing is scheduling daily recovery points for the most recent 30 days and then keeping only 1 recovery point per week (or month) past that.  DPM would have to delete the daily recovery points older then 30 days and leave only one per week.  This would be an awesome, Hybrid type solution that would give us the best of both worlds.  Long term recovery and granular short term recovery together.

    2. Is there any plans to increase the number of recovery points past 64?

  • Hi,

    The way that VSS snapshots work prohibit that from working.  Old snapshots depend on newer snapshots, and if you delete intermediate snapshots, they actually don't get deleted from disk, as VSS still needs them to be able to recover from older snapshots, so no disk space would be freed / gained.   That is why we have shadow copy protection mode, if VSS cannot maintain the active snapshot, Windows VSS prohibits new writes from occurring otherwise Volsnap would delete all previous snapshots.

    As to the question of maintaining more than 64 snapshots, that is a Windows VSS limitation, not a DPM limitation, so if a time comes that Windows supports more, then DPM can support more.

  • Got it.  Thanks for the response.  Those additional features would add a ton of value to the DPM product.  Any idea if there are any plans fro the windows team to increase the VSS limit?

  • Hi,

    I was hoping Windows 2012 would, but it didn't, so no telling what the plans are.
