Ppdg Robust File Replication

1) Many groups presented file replication systems they have developed and are using in production, including JLAB, SRB, Globus, GDMP, MAGDA, SAM, STAR, and BaBar. 2) The systems utilize various components like replica catalogs, file transfer services, storage interfaces, and scheduling/management layers to provide robust file replication capabilities. 3) Key topics of discussion included interfaces and standards for replication services, error handling, reliability, performance, and experience from different experiments. Groups expressed interest in further collaboration in these areas.
