Feature Overview

CFS provides a scheduled snapshot feature, enabling developers to flexibly set backup task policies.
It is recommended to adopt different scheduled snapshot policies for different business scenarios. The recommended settings are as follows:

Business Scenario Snapshot Frequency Snapshot Retention Time
Core businesses Use scheduled snapshots and set the policy to once a day. 7 days to 30 days
Non-core and non-data businesses Use scheduled snapshots and set the policy to once a week. 7 days
Archiving businesses Manually create snapshots based on actual business needs, without the need to set a fixed frequency. One month to several months
Testing businesses Manually create snapshots based on actual business needs, without the need to set a fixed frequency. Promptly deleting after use
