Chapter 7. Data storage policies

archives are retained for 100 days (Example 7-5). Files that are changing during
archiving are not stored. If it later turned out that we had additional archive
requirements, for example, to keep certain files for seven years, we could easily
define a suitable archive copy group in an existing or new management class.
Example 7-5 Defining archive copy group
tsm: ATLANTIC>
define copygroup server server data type=archive
destination=diskdata retver=365 serialization=shrstatic
ANR1535I Archive copy group STANDARD defined in policy domain SERVER, set
SERVER, management class DATA.
tsm: ATLANTIC>
define copygroup workstn workstn data type=archive
destination=diskdata retver=100 serialization=shrstatic
ANR1535I Archive copy group STANDARD defined in policy domain WORKSTN, set
WORKSTN, management class DATA.
7.2 Verifying policy definitions
To check the policy definitions, use the
query copygroup
command. The output
displays the policy domain, policy set, management class, and copy group
names, as well as the copy group parameters. Note that it is really the copy
group definitions that define the policy for the domain; the rest of the constructs
between the domain and copy group just provide flexibility in your configuration.
7.2.1 Backup copy groups
Example 7-6 shows how to check the settings for the recommended backup copy
groups, using the
query copygroup command to display the attributes.
Example 7-6 Querying backup copy groups

query copygroup server server type=backup
