  The ufsdump command copies files. directories, or entire file systems from a hard disk to tape or from disk to disk. The only drawback of using ufsdump is that the file system must be inactive ( that is, unmounted or read-only) before you can conduct a full backup.

You can use the fssnap command to create a read-only snapshot of a file system while the file system is mounted. A snapshot is a point-in-time image of a file system that provides a stable and unchanging device interface for backups. This snapshot uses the backing-store file.
