Prior Confirmation
Check the following items before creating an archive.
The state of the existing archives
Confirm that the state of all the archives is "Archived". If there are archives in a different state, refer to "4.3.2 Archive State" and take the necessary actions to change the state to "Archived". New archives can be created only when all the archives are in the "Archived" state.
Unused license capacity
Archives can be created when the used datastore capacity is less than or equal to the free space of the license capacity.
Open the Used datastore/archive capacity panel in the CSG Web GUI dashboard and make sure that the value of Datastore is less than or equal to that of Unused.
If the value is larger than that of Unused, it means that the license capacity is short of that capacity gap so, archives cannot be created. Refer to "2.5.6 Registering a License" to register an additional capacity license that is greater than the lacking capacity.
Point
When data is being transferred from this product to a cloud provider, the Datastore value fluctuates. After the data transfer is completed, compare the Datastore value with the Unused value. The completion of the transfer can be checked from the No display for Untransferred data in the Used cache capacity panel.
The free space in the storage pool for cache and archive operations
Check the free space in the storage pool for cache and archive operations by referring to steps 1 and 4 of "2.4 Allocating the Virtual Disks to a Storage Pool for Cache and Archive Operations".
The free space required to create an archive is at least 10%(minimum of 20 GB) of the used datastore capacity. If the free space is insufficient, refer to steps 1 and 2 of "6.8 Expanding the Cache Area by Adding Virtual Disks" to expand the capacity of the storage pool for cache and archive operations.
Point
The entire unused area of the storage pool for cache and archive operations is used as a work area to create archives.
Accessing to the shared folder
The shared folder is inaccessible from the start of an archive creation until the completion of the internal initialization process. Make sure that users of this product are not accessing the shared folder.
If an archive is created while the shared folder is being accessed, the shared folder forcibly becomes inaccessible. Resume access to the shared folder after the initialization process of the archive creation is completed.
Note
After the creation is started, depending on the amount of archive data, it may take a few hours to a few dozen hours to complete the internal initialization process or to complete the creation.
When linking with the cloud backup script of ETERNUS SF AdvancedCopy Manager, the script cannot be executed during an archive creation. The cloud backup script terminates with an error when executed between the start of and the completion of an archive creation. In addition, while the cloud backup script is being executed, creation of an archive terminates with an error.
Information Required in the Basic Settings Screen
Item | Required? | Description |
|---|---|---|
Archive name | Required | Specify a name with up to 32 characters to identify an archive. You can use alphanumeric characters and symbols (!@#$%^&*()_+-=[]{}|'). In the Enter basic settings screen, "AR#nnnn" is displayed as the initial value. "nnnn" is a four-digit number beginning with 1. |
Datastore name | Required | From the pull-down list, select the name of the datastore whose archive is to be created. |
Storage class | Optional | To save the archive, select "S3 Glacier" or "S3 Glacier Deep Archive" as the storage class. "S3 Glacier" is selected as default. |
Description | Optional | Specify the description of the archive within 256 characters. |
Point
In this product, you cannot check whether the storage period of the archive has passed the minimum storage period for the archive storage.
Therefore, it is recommended to include the creation date of the archive in the archive name or the description.
Procedure for Creating an Archive
In CSG Web GUI, click Archive on the global pane.
The Archive list screen is displayed.
Click Create in Action on the right.
The Enter basic settings screen is displayed.
Refer to "Information Required in the Basic Settings Screen" to enter the required information and then click Next.
The Confirm screen is displayed.
Confirm that there is no problem with the content that is displayed and then click Done. The shared folder becomes inaccessible after the button is clicked.
Check the Archive list screen.
Confirm that the archives in the "Creating" state are displayed and wait until the creation is completed.
After the initialization process for the creation is completed, "Creating (xx%)" is displayed for the status to show the progress. After this, the shared folder can be accessed.
The time required to complete the creation ranges from a few hours to a few dozen hours depending on the amount of archive data. After archives are created, the status shows "Archived".
See
You can also create archive with the CSG REST API. Refer to "Archive" in the "Reference Guide" for how to create archive.
Point
This product does not have the scheduler function to automate archive creation. To automate a creation, call CSG REST API from an external scheduler such as Windows Task Scheduler.
