I have a server I bought from EV1. The disk is full, so I need to upgrade the sever to a larger disk, however, The Planet tells me this will amount to a server restore. So two questions:

one, what is the best method to upgrade the disk without losing time in installing all the software, configuration, user accounts etc., and transferring the data? I am thinking something like, insert a new blank disk as a slave disk, with an active partition; move everything from the current master disk to the slave (Ghost for Linux? RSYNC? Dump? what works best?), swap disks and boot. If everything works, than remove the old master disk.

second, suppose I went with two disks in the new server (that is, two brand new disks) and decided to backup everything from the master to the second disk (just in case the master disk fails), then what is the best method? Dump/Restore? RSYNC? Mirror?

advise much appriciated, and thanks in advance.
