Hi,
I have a HD LVM partition present in /dev/mapper/disc-p1
When un-mounted, I wish to back it up to a remote machine. It should
appear on the remote machine as a file. So I can mount it using the
loopback device if needed.
I only want to transfer blocks on the partition that have changed
since the last backup.
rsync does not seem to support block devices.
Are there any tools in Linux that can do what I want?
As a work around I might try converting the block device into a file
on the source machine and then rsync will work on it.
