Create a Data Policy
8.
Select the type of
Versioning
you want to use for the data policy. You must select either
None
,
Keep Latest
, or
Keep Multiple Versions
.
IMPORTANT
If you select
Keep Multiple Versions
, you are not able to change this setting
after the data policy is created.
•
None
—Only one version of an object may exist at any time and the version number of
the object is always 1.
•
Keep Latest
—Only one version of the data is available at a time. When a new version
of an object is written, the old version is retained until the new version is fully
written in compliance with the data policy, and then the old version is deleted.
•
Keep Multiple Versions
(
default
)—When a new version of an object is written, it is
added as the latest version of the object. Any previous versions of the object, up to
the value specified, are retained and accessible. The default value of 1000 is pre-
entered.
Notes:
• The
Keep Latest
setting cannot be used for a data policy which uses a storage
domain configured with the
LTFS File Name
option set to
Object Name
. See
Create a Storage Domain on page 118
for more information.
• The
Keep Latest
setting requires that the PUT job for the earlier version of the
object complete before the PUT of the latest version of the object with the same
name in order for the PUT job to succeed.
CAUTION
If you select
Keep Multiple Versions,
if the PUT of the earlier version is not
complete before the PUT of the latest version, the BlackPearl system believes the
latest version to be the same object as the earlier version and rejects it, and only
the earlier version is retained.
9.
If you plan to configure a data replication target, select or clear the
Always accept
replicated PUT jobs
check box. This option controls whether all PUT jobs for this data
policy are created even if one or more replication targets the system must PUT to are
unavailable, or if there are global issues that would likely prevent the completion of the
job.
Note:
Using this parameter is discouraged, and using it for jobs on both the source and
target systems at the same time is extremely discouraged. Running jobs on both
systems when they are not able to communicate with each other can create
replication conflicts that must be manually resolved.
