    Hi,When I do a snapshot backup of a KVM whose disk is on LVM, does it only backup the portion of the disk in its state at the point of when the snapshot starts? For example, if I start the backup before starting to compile an app, does it include all the partial disk writes that occur after I start the b/u while I'm compiling?Thanks,-J

    The backup is doing a backup of the state of disk, at the moment when backup start.

    So, no, you'll not have partial disk write after backup start
