you can query for all Microsoft Office documents written by a specific

Single Instance Storage

SIS recovers disk space by reducing the amount of redundant data stored

in a volume. To recover the disk space, SIS performs the following

procedures:

•

Identifies identical files

•

Stores one copy of the file in the SIS common store

•

Replaces the files with pointers to the file in the SIS common store

For example, User A and User B receive the same e-mail with an

attachment. Both users save the attachment to their home folder.

SIS detects the two identical files on the volume, moves one of the

copies into the SIS common store, and then replaces both files with a

pointer to the file in the SIS common store.

Subsequently, User A makes a change to the file. SIS immediately detects

that an update is pending for the file, removes the pointer in the user's

home folder, and replaces the pointer with a copy of the file in the SIS

common store. The updates are then applied to a fresh copy of the original

file. This process is completely transparent to the application.

The User B file remains in the SIS common store with a pointer in the

User B's home folder, even if there is only one pointer to the file. When

User B updates the file (assuming there are no other pointers), the pointer

is deleted and replaced with a copy of the original file. The file in the SIS

common store is deleted.

SIS works in the background and does not require user intervention. The

administrator can enable SIS on a per volume basis. For best results, the

administrator should use a backup application that supports SIS.
