Jagane,
Reading your page, the first thing I stumble upon under 'Use Cases' is
the reference to EBS storage. What is that?
Under details, I think it is not a good idea to rely on QEMU looking for
any files with specific file name suffixes. It really should be
specified on the command line by the user or admin tool.
Other questions, how do you plan to handle crashes or loss of network
connection in the middle of a livebackup? How about handling corrupted
livebackup files?
In general it looks interesting, you could consider submitting a
presentation about Livebackup to the KVM Forum 2011.
Cheers,
Jes
