A backup and recovery strategy cannot be created based on disk size and random guesses as to what is "ideal". A backup and recovery strategy is based on how your company and users use the data! If your company is processing credit card or similar database transaction, and the server is busy, you might be well advised to backup certain files twice a day.

Or, for example, if you have many users on the platform who are writing software, then you must backup, at a mininum, every day, because people get very unhappy when the accidentally delete a file and there is no backup.

The same is true for web hosting and myriad other applications.

Phantom did a good job to begin to describe the process of developing a backup and recovery strategy.

"Know your data." "Know your users."

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.
