And unfortunately there is no obvious indication that this occurs in the Hyper-V manager apart from an Action option called something like "Cancel Merge in Progress". It would be nice if there where some other way to know the merge status. Each of the AVHD files will be automatically deleted once the merge has incorporated them into the VHD and this may take a long time if you have large snapshot files. You can restart the VM but this will cancel the merge and it will have to restart once turned off again back at the beginning last AHVD file to be accessed. It appears that a lot of people don't even know this occurs and go about doing this under their own steam instead of letting Hyper-V do so automatically.Rod Dineshttps://www.blogger.com/profile/01189989933124387430noreply@blogger.comtag:blogger.com,1999:blog-158104178192097877.post-69010989850370808212011-12-22T04:11:55.909+11:002011-12-22T04:11:55.909+11:00I was able to find updated information on http://b...I was able to find updated information on http://blogs.msdn.com/b/virtual_pc_guy/archive/2009/04/16/what-happens-when-a-snapshot-is-being-merged-hyper-v.aspx that explains why merge in reverse order.<br /><br />The merge happens from the most recent diff disk into the previous diff disk.

It sounds like you would want to do the oldest snapshot and work to the most recent.<br /><br />My concern with this is for example.<br /><br />I have original file, day 2, day 3, day 4.<br /><br />If I was to follow your example... I would merge day 4, then day 3, and finally day 2.<br /><br />So I made a change on day 2... added a new website.<br /><br />Then day 3 I made significant changes to the website content.<br /><br />Finally on Day 4 I made security changes to the website and installed Windows updates.<br /><br />Would the changes from day 3 overwrite the security changes from day 4… and more concerning would the new content added on day 3 be overwritten by the original form of the website from day 2?<br /><br />Would you please help me find a production website that would confirm the reasons for the backwards recovery?Khayhttps://www.blogger.com/profile/10552091732449750875noreply@blogger.comtag:blogger.com,1999:blog-158104178192097877.post-68427757700402467672011-12-08T10:25:08.160+11:002011-12-08T10:25:08.160+11:00good stuff. thanks for sharing.good stuff. thanks for sharing.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-158104178192097877.post-49598120845409471652011-12-01T02:52:03.865+11:002011-12-01T02:52:03.865+11:00The link to Jason's post is broken, so I'm...The link to Jason's post is broken, so I'm not sure if something is explained there, but...<br />What is the point of renaming the .avhd files?

When I shut down the VM and open the setttings and click on the hard drive, the Edit option is disabled with a warning that "Edit is not available because snapshots exist...". Ah, how is one supposed to merge the snapshots.<br />Other articles say that using the Delete Snapshot or Delete Snapshot tree will merge. Is it really that simple? To me the word "Delete" means that I'm discarding the delta saved in the snapshot--not merging it into the base so the resultant VM will contain the changes made in the snapshot.<br /><br />Clarification?William Vaughnhttp://betav.com/blog/billvanoreply@blogger.comtag:blogger.com,1999:blog-158104178192097877.post-91462394429134675532011-08-29T09:17:00.986+08:002011-08-29T09:17:00.986+08:00How about:
