Recursive snapshots

[STREBLO]

I am kind of confused about the difference between recursive and normal snapshots.

When you take a normal snapshot, shouldn't it include everything inside it anyway? How can you have non-recursive snapshots?

Is it okay to be taken snapshots of a dataset, lets call it dataset1, at high frequency intervals and also taking snapshots higher up your tree, lets call dataset0, that happened to include the first dataset as well?

For example, we have:
/dataset0
|------ dataset1

And we take a snapshot of dataset1 every 5 minutes and a recursive snapshot of dataset0 once a day. Is there any reason not to do this? Does one of the snapshots override another?

Thanks for the information but it didn't really answer my question , and I've been having trouble finding any really well explained information on this.

Recursive snapshots include everything (datasets, folders, files, ...) that's inside the snapshotted dataset.

Non-recursive snapshots include everything but datasets that are inside the snapshotted dataset.

It's totally ok to do that :

I do exactly that because I want to snapshot all datasets once a day (so I take recursive snapshots of the root dataset) but some sub-datasets more often like once every 10 min for example (so I take non-recursive snapshots of those datasets) ;)

Awesome, thanks
