copy filesystems with dump command.

I want to copy one filesystem to other filesystem with dump command on linux red hat 7.1. But I don?t know how.
I think that the command to do this is something like:
restore | dump

Thank you.

you can use dump to make a system backup and then use the restore command to restore that backup onto the other drive

I am not entirely sure that you can pipe the output of dump directly to restore. You might be able to however I recommend dumping to tape and restoring back from it

You can do this. The only obstacle is the that it will include the full path in the restore. Here's an example assuming copying of /home to /home2

dump -0 -f - /home | (cd /home2; restore -x -f -)
This works well, except that the home directory will appear under /home2 and then you just need to use move to rename it to where it should be.
