Size BFS Database

The BFS Database is located under /etc/dm/raima/bfs. This Database contains the bitfile IDs for migrated files. A bitfile ID points to a specific RID (record ID) on AMASS. This is how DataMgr keeps track of where client files have been migrated.

Use the formula below to determine the space required for the BFS Database:

Database size = 64 * Number of files being migrated
