System Administrator’s Guide to Installing DataMgr

If File Replication or Multi-tier Policies are used, then the equation is:

Database size = ((64 + (factor * 16)) * Number of files being migrated

factor = Number of replicated copies or number of tiers.

Example 1: if you have client files using a File Replication policy with 1 primary copy and 1 secondary copy, the equation would look like the following:

Database size = (64 + (1 * 16)) * number of files)

Database size = 80 * number of files

Example 2: if you have client files using a Multi-tier policy with the primary copy and 2 tiers, the equation would look like the following:

Database size = (64 + (2 * 16)) * number of files

Database size = 96 * number of files

Note

A migrated file that is subsequently modified and re-migrated creates a new record in the BFS Database. Also, when a migrated file is removed from a client’s managed file system, it’s record remains in the BFS Database until its retention time expires and the Trashcan is dumped. At that point, the record is available for re-use in the BFS Database.
