Example 23–6 Performing a Full Backup to a Remote System (Solaris 9 Data to Solaris 9 System)
The following example shows how to do a full backup of a local /export/home file system on a Solaris 9 system (starbug) to a tape device on a remote Solaris 9 system (earth) in single-user mode. The following ufsdump options are included:

0 specifies a 0 level dump (or a full backup).

u specifies that the /etc/dumpdates file is updated with the date of this backup.

c identifies a cartridge tape device.

f earth:/dev/rmt/0 identifies the remote system name and tape device

/export/home is the file system being backed up.
