I'm not sure the way the Volume Snapshot Service works you can call it exactly "one full and multiple incremental" backups.
The way it stores the data it's more like "a set of changes describing the recent history of the logical blocks of the drive". It can delete the oldest to make room and still have a full restoral capability.
But the effect is the same - you can restore all the data from multiple different days. What would you like to see to be convinced? The list of available backups to restore from a drive being used to hold such backup? Here you go:. At the moment as you can see I have 3 available. I've seen as many as I was initially confused by the times shown 10 pm , because I do my backups at 1 am, but I'm in Eastern time and by default the backup times are shown in Pacific time presumably because Microsoft engineering runs on Pacific time.
Only thing I had to change was on General tab, where at the bottom, Configure for : had default Vista showing. Now I have selected Windows 8.
I hope this makes the difference. Thanks for the good tips Noel. I had the same experience as Jay Kulsh in that the -vssFull command doesn't make a difference. Having it present or not still results in an incremental backup for the c: drive which is desirable. In my situation I would like to backup the c:,d:,e:,f:,h: drives each night with an incremental backup. The total size of the data on the drives is 5. When I backup c:,d:, the c: drive backup is incremental but the other drive is not.
Is there a way to have the backup be incremental for all of the drives? Thanks for any help. Keep in mind the first backup will have to be full as I'm sure you realize, but I'm stating it for completeness here. The thing I don't have a good handle on is what is the logic for the software to determine whether there's room for an incremental backup on the output media.
It's possible it decides it has to delete the old snapshots to make room for a new one, after which it becomes necessary to copy everything again. I see my backup turn into a more or less full copy every now and then, because the oldest dataset has to be deleted. I see messages in the System event log like this one:.
The oldest shadow copy of volume C: was deleted to keep disk space usage for shadow copies of volume C: below the user defined limit. From my earlier tests of running backup with just c:,d:, there was lots of room for it to copy about 5x extra room on the backup target. The backup target is a network location.
I'm under the impression that only one copy of an image can be saved to a network location. That shouldn't affect whether it's incremental or not since the backup of c: to that network location is incremental.
I checked the Event Viewer and didn't find a message like the one you mentioned. I see that there are information-level messages from Backup that say "The Block Level Backup Engine service has stopped. Do you have other ideas? If not, I could live with weekly backups on the weekend and let it go the 24 hours.
The only concern I have with this is with a failure during the backup which would leave me with nothing. I'm not a cursing man, but I could almost curse Microsoft for removing the Backup and Restore feature from Windows 8. Thanks for the help. You may have something regarding the backup going to a network share. I'm a little fuzzy on the mechanics of it, but it's entirely possible the backup volume itself needs volume shadow copy capability in order to make the backups incremental.
We've reached the limit of my knowledge of the wbadmin feature at this point, as I stopped looking to refine my backup strategy when I found that when using a USB drive it works exactly as I need. Perhaps someone else with more in depth knowledge of Volume Snapshot Services can contribute here Just an FYI, if you are still concerned about whether or not these are incremental, you could at least make 2 tasks that run every other day, storing to two different folders on the drive.
The trick besides what Kael29 pointed out to target the folders , is to add the parameter:. This modifies the daily interval to be every 2 days, which can be confirmed on the "Triggers" tab of Task Schedule. I am not able to test it, because I can't mount the usb restore drive to a hyper-v machine for testing. I have tested restoral of a non-leaf volume snapshot.
It is possible from a USB drive directly. I believe there are limitations with network shares, though, which is probably what you've run into. Office Office Exchange Server. Not an IT pro? Resources for IT Professionals.
