Depending on your network bandwidth you may be able to use remote
mirroring of the holding disk with iSCSI or another IP block device
channel. iSCSI can also do char devices, and Amanda 2.4.3 can do
RAID 1 tape mirroring with the RAIT driver. So you can maintain a
local backup stream and a remote mirrored backup stream at the
same time. If you have enough bandwidth.
