[AusNOG] Offsite Storage

[Robert Hudson]

SSD is bad for long-term offline data storage.  If you're going to keep
data offsite for any significant length of time and wish to do it on disk,
then rotating disk is better (also cheaper per GB, assuming that actually
matters at the volumes you're talking).

Tape is better again than spinning disk, though as you noted, the costs of
implementing it are expensive (requiring the tape drive, a server to drive
it, software on the server, etc).

With the data volumes you're talking about, would something as simple as
Crashplan and its ilk suit?
