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

equation is:

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:

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:

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.

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

factor = Number of replicated copies or number of tiers.

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

Database size = 80 * number of ﬁles

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

Database size = 96 * number of ﬁles
