Question Need basic disk copy routine for AIX 3
I'm using AIX 3 on IBM PowerStation 520's in a couple of flight simulators where I work. I recently upgraded our disk systems from three 355Mb disks to single 2GB flashdisks. The disk backup utility provided by the manufacturer will only copy 355Mb disks.

I need a basic disk copy routine that will duplicate any size drives. Is there something available for AIX 3? There's no chance my employer will upgrade the OS as it would cost almost $1,000,000 per system due to the need to rewrite all the specialized utilities to work with the new OS. Can it be done using only basic commands? It would be nice if files were concatenated (defragged) during the copy process.

Any tips or help would be appreciated.

BACKUP(8)						      System Manager's Manual							 BACKUP(8)

NAME

       backup - backup files

SYNOPSIS

       backup [-djmnorstvz] dir1 dir2

OPTIONS

       -d     At top level, only directories are backed up

       -j     Do not copy junk:  *.Z, *.bak, a.out, core, etc

       -m     If device full, prompt for new diskette

       -n     Do not backup top-level directories

       -o     Do not copy *.o files

       -r     Restore files

       -s     Do not copy *.s files

       -t     Preserve creation times

       -v     Verbose; list files being backed up

       -z     Compress the files on the backup medium

EXAMPLES

       backup -mz . /f0    # Backup current directory compressed

       backup /bin /usr/bin
			   # Backup bin from RAM disk to hard disk

DESCRIPTION

       Backup (recursively) backs up the contents of a given directory and its subdirectories to another part of the file system.  It has two typ-
       ical uses.  First, some portion of the file system can be backed up onto 1 or more diskettes.  When  a  diskette  fills	up,  the  user	is
       prompted for a new one.	The backups are in the form of mountable file systems.	Second, a directory on RAM disk can be backed up onto hard
       disk.  If the target directory is empty, the entire source directory is copied there, optionally compressed to save space.  If  the  target
       directory  is  an  old  backup,	only  those  files  in	the target directory that are older than similar names in the source directory are
       replaced.  Backup uses times for this purpose, like make.  Calling Backup as Restore is equivalent to using the -r  option;  this  replaces
       newer files in the target directory with older files from the source directory, uncompressing them if necessary.  The target directory con-
       tents are thus returned to some previous state.
