Click Create to add a policy or click Update to save the changes.
For Cool tier policies, it can be useful to add a clause for Archived At while adding a filter. It is the date the file was uploaded to Cohesity Alta SaaS Protection. The default or older than one month is typically sufficient as it ensures that the data has time for any post-processing, such as full-text indexing; while on the Hot tier where the data has the lowest access costs.
Archive tier policies automatically exclude data based on the Stors storage tiering settings for the last accessed and items captured in the last N days. The policy runs according to the Policy Evaluation Interval for the selected Stor.
Warning:
Removing a Cool or Archive tier policy causes the data to be moved back to the Hot tier unless there is an overlapping Cool or Archive tier policy. Unwanted access and transaction costs incur and also could charge deletion costs if the data hasn't been on the tier long enough.
