Description Dave Allan 2013-05-15 14:35:15 EDT
+++ This bug was initially created as a clone of Bug #948017 +++

When performing online backups, applications are not aware of guest-agent freeze/thaw commands and therefore the filesystem may be in an inconsistent state due to pending disk flushes.

For Linux, there's support for guest-agent hooks on freeze/thaw (Bug 911569), which can be used to notify applications (or stop/start daemons). On Windows, the correct way to handle freeze/thaw is using the VSS API.

Some details about VSS:

Comment 2 Michal Privoznik 2013-05-16 04:25:30 EDT
I don't think there's a need fro any libvirt integration. However, I'll keep an eye on this, if something pops up.
Comment 3 Michal Privoznik 2013-06-27 11:33:48 EDT
I don't see any room for libvirt involvement here as I've stated in comment 2. Since then the nature of the bug hasn't changed so I am closing this one. If somebody disagrees please do reopen.
