For large installations I tend to recommend SSD (which needs frequent backups because of the style of the RRD write load) or ramdisk (which needs frequent backups, because, well, lol) RRD storage and as an Observium installation consists of db, rrd and a single config file, it's trivially easy to restore in a couple of minutes.
Backing up large amounts of RRD from a fast read storage device like ramdisk or SSD works best if you compress them before writing them, as they compress really well.

Combined with good backups this seems like the easiest option if you're already virtualised (works fine for us), but as observium grows you may find you need the performance of dedicated hardware.
