Hello, Dan,
Thanks for the feedback.
Most of the post seems to deal with ddumbfs. Why not leave that out entirely?
Just to confirm, you are aware that default Bacula Volumes are basically not deduplicable, right?
Yes. I am. I suggest mentioning that at the start of the post. Something like:
Bacula take take advantage of filesystem deduplication with a specially configured Device.
Putting the prerequisites at the top of the post helps readers understand whether or not this article is for them.
The main point is the new Aligned volumes feature.
Agreed. The post needs to concentrate on that feature, not ddumbfs. At present, it makes me think the title should be:
Using ddumbfs for Block-level Deduplication with Aligned Volumes
Ddumbfs FS was the one I had time to test for this laboratory. But of course, there are other options. I will try to do the same with ZFS.
I understand.
If we are not using ddumbfs, it sounds like the only requirements are:
Sorry, I did not complete that sentence. I should have deleted it.
Perhaps a ZFS-only post is worthwhile?
Sure.
If I use ZFS, what filesystem attributes are required?
Hopefully we are going to find out. =)
