The generated report
contains two sections, "Storage reduction by file type", and "Most
shared file types by number of references".
The report's "Storage reduction by file type"
section contains a chart and a table:
-
The chart shows the 10 file types for which there
is the greatest amount of storage reduction due to Enterprise Vault
single instance storage. Note that the horizontal axis is
logarithmic.
-
The table shows the storage reduction due to
Enterprise Vault single instance storage for up to 25 file types.
The table groups any remaining file types as "Others".
Table: Report output: storage reduction by file
type table shows the information that the report provides for
each listed file type.

Description
|
|
File Type
|
The file type for which information is shown.
|
|
Number of Shareable Parts
|
The number of shareable parts (SIS parts) for this file type in
the vault stores.
|
|
Number of References to Shareable Parts
|
The number of references that exist to the SIS parts for this
file type.
Before it stores a SIS part, Enterprise Vault checks whether an
identical SIS part is already stored within the target vault
store's sharing boundary. If an identical SIS part is already
stored, Enterprise Vault references the stored SIS part and does
not store it again.
The ratio of the number of references and the number of parts
gives some indication of the amount of storage duplication
saved.

Total Original Size (GB)
|
Total original size in gigabytes of the archived items, before
any savings that are due to Enterprise Vault single instance
storage.
|
|
Total On-Disk Size (GB)
|
Total size in gigabytes of the items on disk, before they were
archived.
|
|
Storage Reduction (GB)
|
The total original size minus the total compressed size, in
gigabytes. The value indicates the storage reduction that
Enterprise Vault single instance storage has produced for this file
type.
|
The report's "Most shared
file types by number of references" section contains a table that
ranks the file types by the greatest number of references to SIS
parts.
Table: Report output: Most shared file types
table shows the information that the report provides for each
listed file type.
