Diskmirroring

[Tillmann Basien]

Hy guys,
	who know of products to increase disks-security?
	Is it possible to make a diskmirroring?
	Or, how can I connect two systems to store files on both
	filesystems?
	Make it sens  to connect the second systems via NFS and store the
	information in two identical files?
	What happens if one of the system goes down?
	Is there a device-driver which transfer the write-call to the
	filesystem also via tcp/ip to the filesystem of a second system?

	My actual situation is, that I must have two systems. One is the
	mainsystem. The second one has the same files and if the mainsystem
	crashes (disk or the rest of the hardware) the seconde one must do
	the job. (the time difference must be 5 minutes)

	This is a system mirroring.

	This is a general question. Not a problem of a special unix
	plattform.

	I will post a summery
	Tillmann
