Veritas InfoScale™ 7.4.2 Solutions in Cloud Environments

To migrate data from on-premise to cloud storage

1. Create the policy file policy.xml.

   See the Administering SmartTier chapter in the Storage Foundation Administrator's Guide - Linux.

   For a sample policy file:

   See Sample policy file.

2. Create a volume set with existing volumes.

   Note:

   Unmount the file system before creating the volume set. After creating the volume set, mount it at the same mount point.

   # umount mount_path_of_data_volume
   # vxvset -g dg_name make vset_name local_data_volume
   # mount -t vxfs /dev/vx/dsk/dg_name/vset_name \
   mount_path_of_data_volume

3. Create buckets/containers in the cloud storage namespace. See the related cloud vendor documentation for instructions.
4. Create the cloud volume.

   For block-level data migration:

   # vxassist -g dg_name make cloudvol_name size vxcloud=on

   For file-level data migration:

   # vxassist -g dg_name make cloudvol_name size fscloud=on

5. Configure the Cloud target.

   Connector	Command
   S3	# vxcloud -g diskgroup_name \ addcloud cloudvol_name host=host_address \ bucket=bucket_name access_key=access_key \ type=S3 secret_key=secret_key \ [https=true|false] [sig_version=v4|v2] where, secret_key and access_key are credentials to access the vendor cloud services. By default, https is set to true and sig_version is set to v4.
   Glacier	# vxcloud -g diskgroup_name \ addcloud vol_name host=host_address \ bucket=vault_name access_key=access_key \ secret_key=secret_key type=GLACIER where, secret_key and access_key are credentials to access the vendor cloud services. Note: Only file-level tiering is supported with Amazon Glacier.
   BLOB	# vxcloud -g diskgroup_name \ addcloud cloudvol_name \ host=host_address bucket=bucket_name \ access_key=access_key type=BLOB \ endpoint=account_name [https=true|false] where, access_key is the credential to access the vendor cloud services and endpoint is the storage account name of the user. By default, https is set to true.
   Google Cloud	# vxcloud -g diskgroup_name \ addcloud cloudvol_name host=host_address \ bucket=bucket_name type=GOOGLE \ google_config=config.json_file_path [https=true|false] where, config.json is a file that contains the private key, project_id, and client_email values for the Google service account. Download this file in the JSON format from the Service Accounts tab of the GCP Console. By default, https is set to true.

   Note:

   Veritas recommends that you associate each cloud volume with a separate bucket.

6. Add the cloud volume to the volume set:

   # vxvset -g dg_name addvol vset_name cloudvol_name

7. Verify that the cloud volume is appropriately tagged.

   # fsvoladm queryflags dataonly mount_path_of_data_volume cloudvol_name

8. Assign placement classes to the local and cloud volumes.

   # vxassist -g dg_name settag local_datavol_name \
   vxfs.placement_class.LOCAL
   vxassist -g dg_name settag cloudvol_name \
   vxfs.placement_class.CLOUD

9. Assign the policy to the file systems.

   # fsppadm assign mount_path_of_data_volume policy.xml

10. View an analysis report of the data transfer.

    # fsppadm analyze mount_path_of_data_volume

11. Enforce the policy to move the data between the local volume and the cloud volume.

    Note:

    You can create a cron job to schedule the migration of old data onto the cloud volume.

    # fsppadm enforce mount_path_of_data_volume

12. Verify the location of files on the local and cloud volumes:

    # fsmap -a list_file
    # fsmap -a /data1/*
    Volume    Extent Type     File Offset     Extent Size     File
    localvol         Data               0         1048576     /data1/reports-2016-03
    cloudvol         Data               0         1048576     /data1/reports-2016-04

13. Check the free space and used space across volumes in the volume set using

    # fsvoladm list mount_path_of_data_volume
    # fsvoladm list /data1
    devid   size                 used                 avail                name
    0       2097152              356360               1740792              localvol
    1       10737418240          40                   10737418200          cloudvol
