The following example creates a snapshot of the /usr file system. The backing-store file is /scratch/usr.back.file, and the virtual device is /dev/fssnap/1.
# fssnap -F ufs -o bs=/scratch/usr.back.file /usr /dev/fssnap/1 |
The following example limits the backing-store file to 500 Mbytes.
# fssnap -F ufs -o maxsize=500m,bs=/scratch/usr.back.file /export/home /dev/fssnap/1 |
