Thanks Lee. I did look at backuppc before, and I didn't want anything that
compresses files, or used a web interface. Using rsync, it's a matter of scp
to restore, and that's it. I do use hardlinks to duplicate data, so my
storage requirements are kept as small as possible. Just about any CentOS
system can be configured to run backups in the manner I've written up,
nothing extra to install or learn. So, like most things, it boils down to
individual needs and expertise. I know for myself, tape backups just weren't
working well at all.
