Snapshot & Restore Frequency

According to the docs, snapshot operations are online and only store diffs.
Is there any particular reason to not run them at a fairly high frequency?
E.g. every 15 minutes?

Alex,

Yes snapshots are online and yes they do store diffs, but only after the first snapshot which by definition has to copy everything.

As to the question of how frequent to run them, that really depends on your tolerance for loss. The added operational costs are reads from disk and bytes sent over the wire. You can tune this behavior with max_snapshot_bytes_per_sec [1].
