The StorageGRID system allows you to design sophisticated and complex ILM policies; however, in practice, most ILM policies are simple.
A typical ILM policy for a multi-site topology might include ILM rules such as the following:
- At ingest, use 4+2 Erasure Coding to store all objects belonging to the S3 Bucket FinanceReports across three data centers.
- If an object does not match the first ILM rule, use the policy's default ILM rule, Two Copies Two Data Centers, to store a copy of that object in two data centers, DC1 and DC2.
