Changing the default retention setting


When you create a namespace, its default retention setting is Deletion Allowed. Once the namespace exists, you can change this setting at any time. Valid values for this setting are:

An offset from the time the object is created. You specify an offset as numbers of years, months, and/or days. For example, you could specify an offset of two years. Then, an object added to the namespace on March 10, 2011, at 9:45 a.m. would expire on March 10, 2013, at 9:45 a.m.

A retention class. For information on retention classes, see About retention classes.

One of these special values:

oDeletion Allowed — The object can be deleted at any time.

oDeletion Prohibited — The object can never be deleted by means of a normal delete operation. If the namespace is in enterprise mode, however, the object can be deleted by means of a privileged delete operation.

Once an object has this retention setting, its retention setting cannot be changed.

oInitial Unspecified — The object cannot be deleted, but can have its retention setting changed to any other retention setting. This setting is useful for namespaces for which the only enabled namespace access protocol is SMTP.

A fixed date in the future. In this case, the retention period for the object ends at the end of the specified day.

TipWebHelp.png

Tip: If you specify a fixed date, remember to change the default retention setting again before that date occurs. Otherwise, the default retention setting reverts to Deletion Allowed when the specified date arrives.

RoleWebHelp.png

Roles: To view the default retention setting for a namespace, you need the monitor, administrator, or compliance role. To change the default retention setting for a namespace, you need the compliance role.

Configuring object versioning


When you create a namespace, you specify whether versioning is enabled or disabled for it. Once the namespace exists, you can change this setting at any time except while the WebDAV, CIFS, NFS, or SMTP protocol is enabled for the namespace.

NoteWebHelp.png

Note: If a tenant is not allowed to create namespaces with versioning enabled, the versioning setting is not available for its namespaces.

When you enable versioning, you can also enable version pruning. If versioning has ever been enabled for a namespace, you can change the pruning settings for the namespace at any time regardless of whether versioning is currently enabled.

TipWebHelp.png

Tip: To immediately remove old versions of objects, set the number of days to keep them to zero.

HCP maintains a transaction log in which it records create, delete, purge, prune, and disposition operations performed on objects. HCP uses this log to respond to operation-based queries issued through the metadata query API.

For any given namespace, you can choose whether HCP should keep records of deletion operations (delete, purge, prune, and disposition) if the namespace has ever had versioning enabled. The amount of time for which HCP keeps deletion records is determined by the system configuration.

NoteWebHelp.png

Note:  In a namespace that was replicated but is not currently selected for replication, the following sequence of actions can cause objects that were deleted to reappear:

1.You deselect the option to keep records of deletion operations.

2.You reselect the namespace for replication.

RoleWebHelp.png

Roles: To view the versioning settings for a namespace, you need the monitor or administrator role. To change the versioning settings for a namespace, you need the administrator role.

To configure object versioning:

5.In the Versioning panel:

oTo enable or disable versioning, select or deselect the Enable versioning option, respectively.

oTo enable or disable version pruning, select or deselect the Prune versions older than ... days option, respectively.

If you select this option, in the option field, type the number of days old versions of objects must remain in the namespace before they are pruned. Valid values are integers in the range zero through 36,500 (that is, 100 years). A value of zero means prune immediately.

This option is available only if you select the Enable versioning option or if versioning has ever been enabled.

oTo keep or not keep deletion records, select or deselect the Keep deletion records for versioned objects option, respectively.

6.Click on Update Settings.

If the version pruning option is unselected, a confirming message appears.

In the window with the confirming message, select I understand to confirm that you understand the consequences of your action. Then click on Update Settings.

Changing replication options


You can enable or disable replication for a namespace on the namespace Replication panel. While replication is enabled for the namespace, you can change options that relate to replication. While replication is disabled for the namespace, these options are hidden.

The replication options you can change are:

Read from remote system. By default, when you create a namespace, this option is enabled.

For more information on this option, see Replication benefits.

ImportantWebHelp.png

Important: Do not disable the read-from-remote-system option unless you have a specific reason to do so.

Accept REST, S3 compatible, and HSwift requests redirected from other HCP systems. By default, when you create a namespace, this option is enabled.

You may want to disable this option if your applications cannot tolerate stale data or metadata. One way to get stale data would be to request an object for which two versions exist but for which the current version hasn’t been replicated yet. In this case, the system targeted by the request would retrieve the old version from another system in the replication topology and return that version to the application.

For more information on this option, see Replication benefits.

Collision handling. By default, when you create a namespace, this option is set to move objects.

For more information on this option, see Replication collision handling.

Allow erasure coding. If allowed by the tenant configuration and if you make the namespace cloud optimized, when you create a namespace, you can choose whether the namespace allows erasure coding.

NoteWebHelp.png

Note: Allowing erasure coding for a namespace that has shredding enabled as the default for new objects can significantly increase the load on all systems in the replication topology. For information on shredding, see Default shred setting.

For more information on this option, see Replication implementation.

TipWebHelp.png

Tip: You can also enable or disable replication for namespaces and, if allowed, manage erasure coding on the Replication page. For information on using this page, see Selecting or deselecting namespaces for replication.

NoteWebHelp.png

Note: While the tenant is being replicated, if you disable replication for a namespace that has already been replicated and then delete the namespace on one or more systems, the namespace deletions are not replicated. If you then reenable replication for that namespace and the namespace still exists on one or more systems, the namespace is replicated back to the systems where you deleted it.

ImportantWebHelp.png

Important: Disabling replication or the read-from-remote-system option for a namespace that has already been replicated may cause object data in that namespace to become inaccessible on one or more systems in the replication topology.

Note: HCP system administrators can delete service plans regardless of whether they’re associated with any namespaces. In this case, the service plan name remains associated with the applicable namespaces, but the service plan is not available to be selected for any namespaces. HCP uses the Default service plan for the namespaces associated with that service plan name.

In the list of service plans, a deleted service plan has no description.

6.Click on Update Settings.

Changing the retention mode


The retention mode of a namespace is either enterprise or compliance. You can change a namespace in enterprise mode to compliance mode, but you cannot do the reverse.

NoteWebHelp.png

Note: If a tenant is not allowed to create namespaces in compliance mode, the retention mode setting is not available for its namespaces.

When you change the retention mode of a namespace from enterprise to compliance, you have no guarantee that objects that should have been retained were not already deleted.

Important: Changing the retention mode of a namespace may violate local regulations regarding data retention. Before taking this action, be sure you understand the implications.
