In CODE EXAMPLE 3-19, the files in directory data are archived when their archive

age reaches one hour.

Unarchiving Automatically

If you specify more than one archive copy of a file, it is possible to unarchive all but

one of the copies automatically. You might want to do this when the files are

archived to various media using various archive ages.

CODE EXAMPLE 3-20 shows the directive that specifies the unarchive age. The first

copy of the files in the path home/users is archived six minutes after modification.

When the files are 10 weeks old, second and third archive copies are made. The first

copy is then unarchived.

For more ways to control unarchiving, see “Controlling Unarchiving” on page 80.

Specifying More Than One Copy for Metadata

If more than one copy of metadata is required, you can place copy definitions in the

directive file immediately after an fs= directive.

CODE EXAMPLE 3-21 shows an archiver.cmd file that specifies multiple metadata

copies.

In this example, one copy of the metadata for the samfs7 file system is made after 4

hours and a second copy is made after 12 hours.
