-Most of our Linux servers/desktops will have a partition mounted to ''%%localtmp%%''.  When we install Linux, most of the hard drive on a server or desktop will go to this partition.  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 "reimage" a server, this partition will //not// be erased and anything stored on this partition will be in the same place after reimaging.

-**This data is not backed up**.  Anything that you delete from this partition can not be recovered.  Also bear in mind that every storage device will eventually fail, in the event of a hard drive failure we will **not** be able to recover data from this partition.

+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, especially since most new servers use SSD disks for their primary disk drives.
