So I think you are after creating media that you can recover your OS from in the case of a total server loss or something catastrophic happening that prevents you booting.

There are a number of products out there.

AIX has mksysb built in
HP-UX has Ignite
I think Solaris has one too (can't remember the name)

...and these are generally free with the OS. Working on Linux, however, you may have to consider one of the following:-

If you are running as a virtual machine (VMWare etc.) there will be tools in the host to make and copy an image of your boot disk. Perhaps called a snapshot or clone.
Commercial software Storix, from the team who originally wrote mksysb
Commercial software 'Christie Clone Manager' which may provide this too.
Others may be available, but I haven't come across them yet.

It depends what you have available to you. Each has a different cost (money and effort/resources) to get running according to your needs. Perhaps we can guide you if we know the scenario you are considering.

I'm presuming that your business data is stored by some other method (over the network to a tape library with Networker, Legato, Tivoli, Arcserve, ...... etc.)

You may need to consider how to recover the volume group/logical volume/filesystem structure to restore with too. Be aware that you would need to ensure that your backup/recovery software would need to be included in whatever you write to your boot-media or a know process to install when you need to.

Most importantly, practice the recovery.

Kind regards,
Robin

BACKUP-MANAGER-PURGE(8) 				       backup-manager-purge					   BACKUP-MANAGER-PURGE(8)

NAME

       backup-manager-purge - backup-manager's wrapper for outdating files

SYNOPSIS

       backup-manager-purge [TTL] <options>

DESCRIPTION

       backup-manager-purge is the only authorized entity that can say if an archive should be purged or not. Any tasks used by backup-manager may
       have to know if an archive is deprecated (eg: the purging phase of an upload method). This tool is here to fulfill that need.

       Given a time to live (TTL) and a list of archives, backup-manager-purge will return another list of archives, corresponding to the ones
       that are outdated by the TTL.

REQUIRED ARGS

       --ttl=time-to-live
	   Specify the time to live (in days) for the archives. Any archive that is older than ttl days will be outdated.

OPTIONAL ARGS

       --files-from=file
	   A file containing a list of archives to parse, one archive per line.  If this option is not used, STDIN will be used for catching the
	   files to parse.

RETURN

       backup-manager-purge will return the list of outdated files on STDOUT, one file per line.

ERROR CODES

       If an error occurs, it will print the error message on stderr and will exit with an error code greater than 0.

       Here are the possible error codes:

       bad command line (wrong arguments) : 10
       internal error (should be reported as a bug) : 20
