Okay, (trouble report, see the end of the email. Successes first :)
I've got the latest 1.7 release. I'm testing right now on Vista Home.
Just as an FYI, this machine has 32 snapshots in place. Going back to
Thanksgiving. All of these were created automatically by Vista. I
don't think I did any config work etc. to make it happen.
I can see these from the Vista Command Prompt by running "vssadmin
list shadows".
Very cool.
dd seems to be working great, but I've only done a couple quick tests.
dd if=3D<global-device-path> | od -cv | less
is showing what looks like good data.
I tried the same with snapshot instance 33. As hoped dd came back
with an error message since that snapshot does not exist.
I currently have 5 dd's running against 5 different snapshots and the
output going to /dev/null. Per task manager all are actively
reading data. Very cool. They are reading very slowly, but then
again I'm beating the heck out of the drive.
I tried the "dosdev" trick from one of the links to mount the snapshot
as V:. Apparently that is a XP only trick. Or at least Vista does
not have it.
=46rom the Vista command prompt I can do:
mklink /d C:\shadow_copy21 \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy21\
and then cd into that directory and see my old snapshot data. I can
also see it from the Vista file explorer.
=46rom cygwin's shell if I try to do so I get:
$ cd /cygdrive/c/shadow_copy21
bash: cd: /cygdrive/c/shadow_copy21: No such file or directory
I assume that should work?
Thanks
Greg
