Is DPM 2010 able to go past 64 recoverypoints RRS feed

  • Question

  • If you set the maxshadowcopies value on a protected server beyond the default of 64, will DPM 2010 be able to create more than 64 recovery points?

    thanks

    I appologize, I meant to say "DPM will Not be effected by any modifications to those keys, all calculations for retention are based on 64 client assessible shadow copies."

  • Hi,

    Windows only supports 64 "client accessible" shadow copies which is used for Volume and Share protection in DPM.  Application data backup (like sql, exchange, sharepoint)  support 512 shadow copies.

  • According to documentation, you can boost the number past 64.

    Just wondering if that registry entry....if it does boost the number of client accessible shadow copies, if DPM would pick up on them?

    thanks

  • So if we modify the number to something higher (up to 512), DPM will recognize it. Is this supported?

    thanks

    thanks
