30.4 Reducing the Size of Libraries and
Document Storage Areas
The amount of disk space you allow at each post office for your library databases varies according to
the GroupWise features they use.
If you are using GroupWise Document Management Services, you must determine storage
requirements for your documents. If you feel your current disk space usage by documents is not
representative of your long-term requirements, you can estimate the disk space users need for
documents by multiplying an average document size by the average number of documents per user
by the total number of users in the post office.
For example, the typical document size is 50 KB. Each user owns about 50 documents and there are
100 users on your post office.
Sample Calculation:
50 KB (document size)
x 50 documents (per user)
x 100 users
-----
2.5 GB of disk space
Be sure to allow your libraries room to grow.
When room to grow is no longer available, the following tasks help you make the best use of
available disk space:

30.4.1 Archiving and Deleting Documents
Documents can be archived, retained indefinitely, or simply deleted. The document type property
determines a document’s disposition (archive, delete, or retain). The document life property
determines when it can be archived or deleted. When you run the Archive/Delete Documents option
of Mailbox/Library Maintenance, documents in the selected libraries that have reached their
document life dates are either deleted or archived.
Documents that have reached their document life and been marked for deletion in the document type
are simply deleted from the library, after which the document and its property information can no
longer be found by any search. You can recover deleted documents from database backups.
When documents are archived, their BLOBs are moved to archive directories. These directories are
named
ar nnnnnn
(where nnnnnn is an incremented integer with leading zeros), and are
automatically created as needed. They are sometimes referred to as archive sets. The archive
directories are located at
post_office_directory \gwdms\lib 01-FF \archive
. When a
document is archived, GroupWise determines if the document BLOB fits in the current archive
directory. If the BLOB does not fit, another archive directory is created and the BLOB is archived
there.
