Shadow copy creation failed: DoSnapshotSet didn't finish properly

gchen    Nov 14 2:25PM 2017

This is caused by the DoSnapshotSet call taking longer than 60 seconds (line 476 in duplicacy_shadowcopy_windows.go)

    if !async.Wait(60) {
        LOG_ERROR("VSS_SNAPSHOT", "Shadow copy creation failed: DoSnapshotSet didn't finish properly")
        return top

I need to think of a way to allow this value to be customized, but for now I can get you a special build with a larger value if you want.

so this doesnt have to do with the app not actually being a VSS writer?

there isnt a ton of data 200 GB..... its going to be worse on my customers who have a terabyte of data or so

But yes i really need help to fix this....

Can i take apart the build and change it myself.... just tell me how.... i'm not sure codeish

but i can try

To build the CLI executable, follow the instructions here:

Once you have the executable, rename it to duplicacy_win_x64_2.0.9.exe and copy it to C:\Program Files (x86)\Duplicacy or C:\Users\username\AppData\Local\Duplicacy to overwrite the existing one.

yeah....i got completely lost.... i need to take you up on your offer of a custom build....

can we connect and get that done Gilbert.....i need a long enough time to accommodate at least 1TB for many of my clients.... the one that got hung was only 200 mb

Here is the custom build:

The timeout has been increased to 180 seconds. It is perhaps enough for most cases but if not I'll add an option to set to arbitrary values.

thank you so much... i will report back

what does this mean??

08:01:45.639 Failed to list subdirectory: open E:\/.duplicacy\shadow\/System Volume Information: Access is denied.

it seems like the shadow copies still failing?? it is because of this??

do i need to exclude this .duplicacy directory from the backup?

gchen    Nov 22 6:14PM 2017

That just meant that you don't have the permission to access E:\System Volume Information, even with shadow copy.

You can exclude this directory by adding this line to .duplicacy/filters:

-System Volume Information\
