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. When it locks it it probably interrupts the PPTP tunnel which causes them to have to reestablish just a guess [11/20/2015 11:17 AM] Treat, Tyler: quiescing? [11/20/2015 11:18 AM] Treat, Shellie: Quiescing indicates pausing or altering the state of running processes on a computer, particularly those that might modify information stored on disk during a backup, to guarantee a consistent and usable backup. Quiescing is not necessary for memory snapshots; it is used primarily for backups. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1015180 ________________________________________ From: [email protected] <[email protected]> on behalf of Josh Luthman <[email protected]> Sent: Friday, November 20, 2015 9:53 AM To: Scott Lambert Cc: Mikrotik discussions Subject: Re: [Mikrotik] VM snapshot breaking tunnel 1 of my VMs are Windows.
