Before you use SnapCenter to back up Oracle database resources, you must create a backup policy for the resource or the resource group that you want to back up. A backup policy is a set of rules that governs how you manage, schedule, and retain backups. You can also specify the replication, script, and backup type settings. Creating a policy saves time when you want to reuse the policy on another resource or resource group.
For details, see the information about defining a data protection strategy for Oracle databases.
For information about how administrators assign resources to users, see the SnapCenter installation information.
You must specify whether you want to back up all the database files, only datafiles and control files, or only archive log files.
If you are using Oracle 12c database, and want to save the state of the pluggable databases (PDBs) before creating the backup, you must select Save state of PDBs. This enables you to bring the PDBs to their original state after the backup is created.
You can perform deferred cataloging for one backup at a time only by using the SnapCenter CLI command Catalog-SmBackupWithOracleRMAN.
If you want to... | Then... |

Delete all archive logs | Select Delete all archive logs. |
Delete archive logs that are older | Select Delete archive logs older than, and then specify the age of the archive logs that are to be deleted in days and hours. |
Delete archive logs from all destinations | Select Delete archive logs from all the destinations. |
Delete the archive logs from the log destinations that are part of the backup | Select Delete archive logs from the destinations which are part of backup. |

Keep a certain number of Snapshot copies | Select Total Snapshot copies to keep, and then specify the number of Snapshot copies that you want to keep. If the number of Snapshot copies exceeds the specified number, the Snapshot copies are deleted with the oldest copies deleted first. Note: The maximum retention value is 1018 for resources on ONTAP 9.4 or later, and 254 for resources on ONTAP 9.3 or earlier. Backups will fail if retention is set to a value higher than what the underlying ONTAP version supports.
Important: You must set the retention count to 2 or higher if you
plan to enable SnapVault replication. If you set the retention count to 1, the retention operation might fail because the first
Snapshot copy is the reference Snapshot copy for the SnapVault
relationship until a newer Snapshot copy is replicated to the
target.

Keep the Snapshot copies for a certain number of days | Select Keep Snapshot copies for, and then specify the number of days for which you want to keep the Snapshot copies before deleting them. |
For this field... | Do this... |
---|---|
Update SnapMirror after creating a local Snapshot copy | Select this field to create mirror copies of the backup sets on another volume (SnapMirror replication). |
Update SnapVault after creating a local Snapshot copy | Select this option to perform disk-to-disk backup replication (SnapVault backups). |
Secondary policy label | Select a Snapshot label. Depending on the Snapshot copy label that you select,ONTAP applies the secondary Snapshot copy retention policy that matches the label.
Note: If you have selected Update SnapMirror after creating a local Snapshot copy, you can optionally specify the secondary policy label. However, if you have selected Update SnapVault after creating a local Snapshot copy, you should specify the secondary policy label.
|
Error retry count | Enter the maximum number of replication attempts that can be allowed before the operation stops. |
You can also specify the script timeout value. The default value is 60 seconds.
