I looked into these options, and in the end opted for an external
firewire hard drive for *ONE* of my offsite backup systems. I initially
looked at USB, but found it to be somewhat flakey and didn't feel
comfortable relying on it.
I installed a firewire add-in card in the backup server, and am then
using GELI to encrypt the data on the drive. I have a script which
automates the attaching to the geli volume, mounting the filesystem,
rsyncing from various sources, and then unmounting the filesystem...
after which I can turn off the drive and take it offsite with me.
This is on FreeBSD 6.1, so I don't know what, if any, firewire support
is available on 4.x...
ATA "hotswap", from what I gather, is only possible with specific
hardware support, and even then is not something that it was originally
designed for (as far as I am aware)...
Hope you or others find some of this helpful!
