Currently I am using rs= napshot to keep backups of the primary drive on the secondary drive, but I a= m interested in having the second drive have a duplicate copy of the entire f= ile system in a bootable form, updated as the root drive is modified. How would I do this? I don=E2=80=99t really want a RAID0 because I want to also keep the periodic= backups from rsnapshot as the drives are about 10x larger than my data. --=20 This is my signature. There are many like it, but this one is mine.=
