How to open Call Tree Snapshot

[king1975]

Dear All

The system I run has a lot of Call Tree data, so I delete it with a TTL of 3 days.
Recently, a failure occurred and a call tree snapshot was needed, but the TTL had elapsed and the data was deleted.
I would like to inquire if there is a way to preserve Call Tree data for a specific period.

Best Regards.
Thank you.
