Example policy - Epic-Large-File
This example describes how to create a policy to back up very large database files such as the EPiC Database.
To add a policy for a large file
- On the left, select Protection > Policies.
- Select Add.
- Go to the Attributes tab.
- For the Policy type select Epic-Large-File.
- On the Schedules tab, configure the full backup schedule.
- On the Clients tab, add the client name.

- On the Backup selections tab, add the path names.
- On the Epic-Large-File tab, configure the following:
Number of parallel streams
The number of parallel backup streams that are used for a backup selection.
If you have configured multiple backup selections in a policy, each backup selection has this number of streams. For example, assume that the number of streams per backup selection is 4 and there are two entries in the backup selections. In this case there are 4 concurrent streams for each backup selection with a total of 8 streams.
Use multiple MSDP nodes
The option Use multiple MSDP nodes allows backups of data files in parallel, which accelerates the backup and restore jobs. You can use multiple MSDP storage units, a storage unit of an MSDP cluster, or a storage unit of an MVG (MSDP volume group) volume.
The dropdown list contains the available storage items, including MSDP storage units and SLPs that are configured in the system. Select the storage to which you want to distribute the data:
MSDP storage units or SLPs. Select each storage unit that you want to use.
If replication is needed, all SLP targets must be in the same target domain. (These targets include the policy storage SLP and the selected storage SLPs.) This configuration ensures that the data files are in the same domain after replication.
A storage unit of an MSDP cluster.
Note:
Select only this one storage unit. Do not select any other storage units with this selection.
This option distributes data files to multiple nodes in the cluster. The recommended value for Number of parallel streams is a multiple of the number of cluster nodes. If there are 4 nodes in the cluster, the value is 4n. For example: 4, 8, or 12.
A storage unit of an MVG (MSDP volume group) volume.
Note:
Select only this one storage unit. Do not select any other storage units with this selection.
This option distributes data files to the MSDP disk volumes in the MVG volume. The recommended value for Number of parallel streams is a multiple of the number of MSDP disk volumes. If there are 4 MSDP disk volumes in the MVG volume, the value is 4n. For example: 4, 8, or 12.
