When I talked about filesystem deduplication, I meant deduplication based on raw device block changes, which is generally done by some program rather than the OS. I was not referring to "automatic" deduplication that is implemented in an OS filesystem. I probably need to rethink my terminology to ensure that this is clear in the future. > With blocks aligned and metadata seperated from the bulk data. > In that case bacula does not even have to care about dedup. We are not planning to change Bacula's Volume format in the near future; it would destabilize the project too much, and it is very well adapted to keeping backup data. However, since it is Open Source, you are free to experiment. We would be interested to hear what you come up with.
