The following storage types are all NAS devices that have the same options on the Storage Options page:
◆ Celerra Container
◆ Data Domain Storage System Container ◆ Isilon ContainerNAS Container
◆ NetApp Storage System Container
If the Celerra Container, Data Domain Storage System Container, Isilon Container, NAS Container, or NetApp Storage System Container storage type is selected, the following fields must be defined:
1. In the Archive Location field, specify the path to the volumes for this folder. To change the location, click Browse and select a new path to the volumes. The maximum number of characters for the Archive Location field is 1024.
When specifying the path in the Archive Location field, you can specify that path as a UNC path or a local path.
Refer to “Common guidelines for specifying archive location paths” in the EMC SourceOne Email Management Administration Guide or the EMC SourceOne Email Management Console Online Help for guidelines on when to use each type of path. 2. In the Maximum Volume Size (MB) field, specify the maximum size (in MB) of
individual volumes in this folder. The default value is 100 MB. You can change this value to be from 10 MB up to 10000 MB (10 GB). When a volume reaches the maximum volume, it is closed and a new volume is created.
If you set the Maximum Volume Size (MB) field to a value greater than 2048 (2 GB), you will receive a warning indicating that this may make your archiving and retrieval operations take longer.
Refer to “Best practices for setting the volume size” in the EMC SourceOne Email Management Administration Guide or the EMC SourceOne Email Management Console Online Help for guidelines on setting the value of the Maximum Volume Size (MB) field.
3. Specify how long data in the archive folder should be retained by entering a value in the Months to retain field.
Valid values for the Months to retain field are the following: • The default value is 1, indicating 1 month.
• The minimum value is 0, indicating that no retention is specified. If 0 is selected the Enable automatic disposition field cannot be used.
• The maximum value is 1200 (indicating 100 years).
• Consider the following before specifying the retention value:
• Once an archive folder has been marked for retention, the file cannot be modified until it has expired.
• When calculating the months to retain value:
a. Determine the number of months from the current date to the date when the file was last saved.
b. Determine the number of months from the current date to the future date that you want to retain files for.
c. Add the number of months from step a and step b together to determine the value in the Months to retain field.
• If you are storing the data in the archive folder on a NAS storage device that supports data retention, you should be aware of the data retention settings on that device, if any. You should also be aware of the maximum time of retention
supported by the device, as this differs by device. Refer to “Retaining and disposing of archived data” on page 113 for more information on data retention and disposal.
• Retention should not be enabled on archive folders used for SharePoint External BLOB Storage (EBS). For these folders, the Months to retain field should be set to 0. Refer to “Archive folder requirements for SharePoint EBS content” on page 95 for other requirements for archive folders that contain EBS content.
• If you specify a retention period, you should test the retention after it is enabled to verify that it is working as you expect.
4. Select the Enable automatic disposition checkbox to have EMC SourceOne automatically dispose of data in the archive folder when the data is older than the value specified in the Months to retain field. The Enable automatic disposition checkbox is not selected by default.
If you are storing the data in the archive folder on a NAS storage device that supports data retention, you should be aware of the data retention settings on that device, if any (For example, Isilon does not support the automated disposal of objects after their retention has expired). Refer to “Retaining and disposing of archived data” on page 113 for more information on data retention and disposal.
5. The Compress content in containers checkbox determines whether or not to compress the containers written to a device. Unless the target device supports block-level deduplication, select the checkbox to minimize the space taken up on the device and in the Message Center.
Clear the Compress content in containers checkbox if all the following apply: • The target device supports block-level deduplication, for example, Isilon with
OneFS 7.1 or later.
• Block-level deduplication is enabled on the device for the selected Archive Location UNC path.
• Deduplication is more effective than compression for the content being archived (consult the device documentation).
• It is acceptable for containers to take up additional space in the Message Center. Otherwise, select the Compress content in containers checkbox.
Note: If the Storage Type is Data Domain Storage System Container, the checkbox is always clear, to optimize deduplication.
When deciding to use compression, consider the following:
• The Compress content in containers checkbox is selected by default (except for Data Domain).
• After the creation of the archive folder, the checkbox cannot change. • Turning off compression will cause the containers in the Message Center to
consume more space.
• If archiving large audio and video content, and also other content, consider disabling compression for the main container and storing large compressed content outside of the container.
6. Click Next. The New Archive Folder Large Content page appears. 7. Select how to store large content:
• Select the Store all content inside containers option to have all content (including large content) stored within the container for this folder.
• Select the Store large content outside of containers when larger than option to have large content:
– Stored with the content when the large content is less than or equal to the value specified in the KB field.
– Stored separately from the content when the large content is larger than the value specified in the KB field.
8. If the Storage Type is Data Domain Storage System Container, then you cannot edit settings on the New Archive Folder Large Content page because content is always stored inside containers to optimize deduplication.Click Next. The Indexing page of the New Archive Folder wizard appears. Refer to “Using the Indexing page of the New Archive Folder wizard” on page 84.
