Znyx Networks bh5700 - Manual (Page 260)

-t Read files to be saved from a tar file.
-z Zero the overlay area.
-f Do not confirm with user and do not warn if saving
failed. Exit code can be examined to determine success or
failure.
Save only the named file, or save the named
directory to the overlay. Contents of directories must be
created with zmnt.
-l List files that would be written. Do not flash.
EXAMPLES
To zsync only the hosts file:
cd /etc
zsync hosts
If you previously created a snapshot of an overlay to a tar file using zmnt,
zmnt –t overlay.tar
You can use zsync to restore the overlay on the switch directly from the tar file,
zsync –t overlay.tar
The restored overlay will be loaded upon the next reboot.
