[Defect] Not all files appear in the shadow copy #10

Closed candera closed 13 years ago

candera commented 13 years ago

Background

While testing ShadowSpawn, we discovered that a .ost file is not appearing in the shadow copy. Other files in the same directory do appear. This is a big problem: sort of the whole reason for ShadowSpawn is to let you back up things like ost files.

Expected Behavior

A shadow copy should include all the files in the source directory.

Looks like it might be the VSS Shadow Optimization Writer.

Anything listed under the registry key HKLM\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToSnapshot will not be snapshotted. OST files are listed there by default, but it's not clear that you'd want to back up an OST anyway. PST files should (as far as we know) still be shadowed.

We verified that PST files are backed up. Closing as "not a real problem".
