Example 3: ILM rules and policy for better protection for image files

You can use the following example rules and policy to ensure that images larger than 200 KB are erasure coded and that three copies are made of smaller images.

CAUTION:
The following ILM rules and policy are only examples. There are many ways to configure ILM rules. Carefully analyze your ILM rules before adding them to an ILM policy to confirm that they will work as intended to protect content from loss.

Steps

  1. ILM rule 1 for example 3: Use EC for image files larger than 200 KB
    This example ILM rule uses advanced filtering to erasure code all image files larger than 200 KB.
  2. ILM rule 2 for example 3: Replicate 3 copies for all remaining image files
    This example ILM rule uses advanced filtering to specify that image files be replicated.
  3. ILM policy for example 3: Better protection for image files
    In this example, the ILM policy uses three ILM rules to create a policy that erasure codes image files larger than 200 KB (0.2 MB), creates replicated copies for image files 200 KB or smaller, and makes two replicated copies for any non-image files.
