==== /localtmp local disk storage ====

Most of our Linux servers/desktops will have a filesystem ''%%/localtmp%%''.  When we install Linux, most of the hard drive on a server or desktop will go to this filesystem.  It is meant to be local scratch disk space, available for all users, that will persist across Operating System upgrades/re-installation.  If we need to upgrade the operating system on a server, this partition will //not// be erased and anything stored on this partition will be in the same place after the upgrade.

**Files in /localtmp are not backed up**.  Any file you delete can not be recovered.  Every storage device will eventually fail, and in the event of a hard drive failure we will **not** be able to recover files from this filesystem.

The advantage of using the /localtmp filesystem is that the disk is local to the server, and performance can typically be better in comparison to network filesystems.
