> What does the number of objects examined during inventory expiration > include? ADSM differentiates between active and inactive backup files. A backup file is always active when it first arrives from a client. A backup file changes to inactive when the ADSM server finds out that the corresponding client file has been updated or deleted. An inactive backup file is retained until inventory expiration processing discovers that it no longer meets the retention criteria for its management class. Earlier postings to this list indicate that information about active and inactive backup files is stored in different parts of the ADSM database, with different trade-offs between compactness and fast access. As far as I can tell, inventory expiration does not look at the portion of the database used for active backup files. On our system, the number of objects examined by inventory expiration is in good agreement with estimates of the number of inactive backup files. I am not sure how archived and space-managed files fit into this scheme of things. We currently have no space-managed files, and very few archived files in comparison to the number of inactive backup files.
