NAME
    PsiBackup - backup an NFS mounted Psion.

SYNOPSIS
    perl -w PsiBackup.pl [options]

DESCRIPTION
    PsiBackup backs up a Psion Series 3a organizer, mounted to a Unix system
    using NFS. The conventions used in file names are identical to the
    conventions of Psion's PsiWin and RCOM programs.

    IMPORTANT: Before starting the back up, all Psion tasks that use files
    on the disk to be backed up should be manually stopped.

  Options

    -mount *dir*
         The NFS mount point for the Psion. The default value /psion.std/mnt
         corresponds to the default name used by p3nfsd.

    -backup *dir*
         The destination directory for the backup, e.g. /@psion. The names
         of the Psion and the disk will be appended to it to form the actual
         name of the backup directory.

    -name *name*
         Optionally, the name of this Psion system. Useful if you want to
         backup several organizers in the same backup directory.

    -disk *name*
         Identification of the Psion disk to back up. Possible values are i
         (default, the internal disk), a and b (the SSD's), c (the 3-Link
         ROM) and r (the Psion's internal ROM).

    -[no]archive
         Do [not] archive old versions of files under a @archive tree.
         Archiving is default enabled for the disks, and disabled for the
         ROMs.

    -limit *nn*
         Limit the number of archive copies to *nn* versions. Default is 16.
         Note that RCOM maintains only one copy, and PsiWin allows up to 3
         copies.

    -help
         A short help for the PsiBackup command.

    -ident
         Show the program identification.

    -verbose
         Supply verbose progress information during the process.

    -quiet
         Supply no progress information during the process.


ENVIRONMENT
    PsiBackup uses no environment variables.

BUGS
    The program can not stop active applications on the Psion, nor can it
    check the Psion's owner information to verify that the correct organizer
    is being backed up.
