- 2Promoting a clone just switches which is considered the parent and which is considered the child. It remains impossible to destroy the snapshot in between because the original parent is now a child of the snapshot, which is now a child of the promoted clone. On top of that, it is still unnecessarily creating dataset-like constructs where I was just looking to replicate files within the dataset.killermist– killermist2012-06-26 18:05:02 +00:00Commented Jun 26, 2012 at 18:05
- Additionally, on a pool with dedup enabled, I have to disagree with the conclusion on compression slowdown. Copying from a dataset with compression enabled to a dataset with compression enabled, speeds rarely exceeded 5Mb/sec. If one dataset or the other has compression disabled, speeds jump to 10-15Mb/sec on average. With both sides compression disabled, I'm seeing 20Mb/sec easily with spikes higher than that (probably because portions are hitting the dedup table in ram instead of pulling from slower media).killermist– killermist2012-06-26 18:09:57 +00:00Commented Jun 26, 2012 at 18:09
- 2I updated my answer with regard to the cloning. As for compression/encryption/dedup, the slowdowns are more caused by updating the DDT than they are compression or encryption. In my experience the impact of compression and encryption have always been negligible. I guess YMMV.bahamat– bahamat2012-06-26 18:43:02 +00:00Commented Jun 26, 2012 at 18:43

- Add related resources or links
- Always respect the author’s intent
- Don’t use edits to reply to the author
How to Format
- create code fences with backticks ` or tildes ~ ```
like so
``` - add language identifier to highlight code ```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible) <https://example.com>[example](https://example.com)<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
