Hi Sergey,
Not sure what you mean by "I'm controlling write function to vdi file
from kernel", but in general it's possible to use FS's (such as ZFS)
snapshotting capability to take snapshots of live VMs image.
OTOH to be 100% safe, I would pause VM, flush OS write buffers with
'sync', and then copy underlying .vdi.
If you assume image to change insignificantly, maybe it would make sense
to take snapshot once image stabilized, and only backup differences.
Hope that'll help,
Nikolay

Hello,
I have VB running and want to make backup for vdi file. But I only
need to have changed sectors. I'm controlling write function to vdi
file from kernel. Can you please answer is it enough just copy it
while VM is running or I need to suspend it?
TIA
