To restore the HOME directory in RPN mode, enter the following:
:Port_Number: Backup_Name RESTORE
For example, to backup the home directory as MYHOME in port 2, use the
following command in algebraic mode:
ARCHIVE{:2: MYHOME)
To restore the HOME directory in algebraic mode, enter the following:
RESTORE(:Port_Number:Backup_Name)
To restore the HOME directory backup from the previous example, use
