Do you have a keepalive timout set for the PPtP tunnels? I see the option in the PPTP server config. In the old days, when clients ran PPPoE connections from their windows boxes to our DSL aggregators, we would see some clients which never caught on that the PPP connection was dead and would have to be forced in some way from the client's end. Then Cisco IOS gave us a tool to respond to unknown PPPoE session traffic with a disconnect signal. It's been a few years since I've had to think about it. I don't know about the PPtP client options for keepalives. I haven't done PPTP for the past several years since it is about like putting a postcard in an onion paper envelope. Maybe you could convert the client to some other VPN tech which might be more forgiving of a short pause as in this instance as well as being secure? > On Nov 20, 2015 12:20 PM, "Tyler Treat" <tyler.tr...@cornbelttech.com> > wrote: > > > Discussion with my resident VM/SAN expert/wife.... > > > > > > [???11/???20/???2015 11:14 AM] Treat, Tyler: > > look at your email > > [???11/???20/???2015 11:17 AM] Treat, Shellie: > > My guess is the backed does a quiescing when it does the snapshot which > > means it locks the files to take a quick snap.
