Shadow copy support?
kalev(09/10/16 00:18)

FC would be an almost perfect program, if it just supported Shadow Copies (snapshots which make it possible to copy open/locked files).

Currently I manage to copy with setting up a separate snapshot with VSHADOW, however there are some problems associated with that:

-FC does not support UNC address as source, at least the window version (have not tried command line version), and shadow copies are always of type \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy

-If creating a Junction Point to the shadow copy to permit copying, one must go to options to separately set the copy mode to NOT copy the JP, it is easy to forget to go and set the mode back

-> so I would request that FC be able to handle the Shadow Copy internally, so that it will always go perfectly.

After all using Shadow Copy is the only possibility to copy truly *everything* on a Windows XP/Vista/7 system.

FC will not even accept the source directory, if it is a link (MKLINK type /D or /J) to a shadow copy set, the shadow copy must be exposed as follows:

1. first create the directory where sc will be visible
MKDIR zzz

2. then expose it with
VSHADOW -el={GUID},c:\zzz

only now will FC accept c:\zzz as a source for copying. And finally c:\zzz must be removed.

Originally the shadow copy must have been made as a persistent copy (-p option) for all this to work in the first place, and thus the shadow copy needs to be separately deleted, too.

So you see it is a little complicated! And it would be very welcome if FC could do everything relating to the shadow copy internally, not bothering the user with it.
