I just saw this story about how the FBI is now seizing whole data centres: http://tech.slashdot.org/article.pl?sid=09/04/03/231220 and was worrying about how best to protect and preserve my data. Using drbd (async mode) to keep a copy of the data in another data centre seems like a reasonable idea. However, how would this compare to using rsync? Which will be more efficient and safer? It would appear that drbd will keep the data more up-to-date, while rsync may use less bandwidth (because it only gets run periodically) I've also seen some threads on this list and others about using the secondary for backup, and that is an important part of what I want to achieve. Is there any best practice for doing this? Any other comments on these issues?
