Hi Pavan and all: We have committed the RHV support for next release of NetBackup. It would help if we can have a weekly/bi weekly call for next 2 months. If there are no topics then we can cancel the call.
Please let us know if this is fine and we can send a calendar invite. + Renee Thanks Navin Sent from my iPhone > On Jul 30, 2018, at 7:04 PM, Suchitra Herwadkar > <[email protected]> wrote: > > Hi Pavan > Is it possible to discuss this over a call/webex? > It will help us put up our perspective and we can discuss options. > > Let us know! > -Suchitra > > On 7/26/18, 6:44 AM, "Suchitra Herwadkar" <[email protected]> > wrote: > > Hi Ondra and team > > Thanks for helping us out on below answers. > > We recently have reported bug using Bugzilla > https://bugzilla.redhat.com/show_bug.cgi?id=1608452 > > This is regarding download of snapshot disk, having multiple snapshots > before creation of snapshot for backup.
