Hi all,
Because I work for an application what need automatically create a
disk snapshot on OS X.
I read some documents about this. I think we can use the shadow file.
Example, we can mount a disk like this: "hdituilt mount disk -shadow
/shadow.image"
I think at this time all I/O will redirected to shadow file and I can
copy my snapshot from the RAW Device.
But that have some problems. The first that is must need re-mount the
disk, and I think at system run time we can't re-mount the boot
volume.
The second is I can not merge the shadow data to the real device when
after created the snapshot.
Is have any easy way to create a snapshot for local disk?
Thanks,
Xiongjia Le
