To ensure that clients checking in every 10 days receivexdelta content packagesinstead of full content packages,30 content revisionsmust be retained on the Symantec Endpoint Protection Manager (SEPM). Here’s why:

Incremental Updates:xdelta packages are incremental updates that only download changes since the last update, conserving bandwidth and speeding up client updates.

Content Revision Retention:SEPM needs to retain a sufficient number of content revisions to allow clients that check in intermittently (such as every 10 days) to download incremental rather than full content packages.

Default Retention Recommendation:Retaining 30 content revisions ensures that clients are covered for up to 10 days of updates, meeting the requirement for xdelta delivery.

This setup optimizes resource usage by reducing the load on network and client systems.
