Running rsync periodically will probably result in not-quite-uptodate replication when the storm troopers come rushing in and cut your power. If that is not a concern, eg. because your data doesn't change all that often, or you simply don't care about a few lost updates, then rsync is IMHO simpler to set up. In contrast, DRBD does real replication. Depending on your link/network quality and the chosen protocol you can guarantee that local writes are only considered complete if the remote side also has completed. peter. -------------- next part -------------- A non-text attachment was scrubbed...
