Manually Offloading Data to a Cold Tier
Prerequisites
- You must be a fabric user to perform this operation.
- Data tiering must have been enabled on the volume during the volume creation, to be able to offload/recall data.
- To offload data, you must create remote targets. See Creating a Remote Target to add a new remote target.
- To manage data offloading, you must have created storage policies. See Administering Storage Policies to learn more about managing storage policies.
About this task
Data, once offloaded, is purged on the the data fabric cluster to release the disk space. When you delete an entire file, part of a file, or a snapshot, corresponding objects are removed from the tier.
Data is offloaded to the tier
in the same state, compressed or uncompressed, as was stored in the front-end
volume. If data encryption is enabled on the front-end volume (using the
dare
parameter), data is encrypted during and after
offload.
At the volume level, data can be offloaded manually by triggering the offload operation.
Follow the steps given below to offload data manually from a volume to a cold tier.Procedure
- Log on to the Data Fabric UI.
- Select Fabric user on the home page.
- Click the Table view icon on the Resources card. In the tabular list of fabrics, click the down arrow for the fabric that contains the volume.
- Click the ellipsis under Actions for the required volume.
