System file retention policies

By default, system files in the CGC system S3 bucket are deleted after 30 days, and read mapper indexes are deleted 14 days after creation. These defaults can be changed by editing the expire-jobs and expire-read-mapper-index-files lifecycle rules associated with the CGC system bucket.

Note: If the same reference genome or genomes will generally be used for mappings, extending the period read mapper indexes are retained may be of interest. Deleting the files every 14 days could result in the indexes being rebuilt more often than necessary.
