We are rsync'ing large (hundreds of GB) and constantly changing Berkley DB (aka Sleepycat) datasets (the RPM database uses the same thing, but its dataset is extremely small). When a change occurs (insert, update, delete, etc) in a BDB it has a tendency to propagate through the binary database files such that rsync has to re-download a great quantity of old data (much like the recent example of why you shouldn't gzip large files before rsync'ing them).
Are there any known methods for making rsync backups of these databases more efficient? -Chuck -- http://www.quantumlinux.com Quantum Linux Laboratories, LLC.
