The Enable Long Term Retention (LTR) option is available only for the backup policies with the LTR-eligible retention period.


πŸ“ Note
​In the case of Hyper-V and VMware, when you enable LTR for a backup policy, the file-level restore on cold recovery points is not supported.


Suppose you have enabled the LTR on a backup policy, and based on this backup policy, your data is moved to the cold tier. Upon disabling LTR, data will stop getting transferred to the cold tier. However, your existing data in the cold tier will remain in the cold tier until it expires.

This article describes the procedure to enable Long Term Retention (LTR), monitor your savings via LTR, and restore the cold recovery points from the cold tier. You will also find information on the deletion of cold recovery points and the early delete fees. We recommend that you read About Long Term Retention before proceeding to read this article.

Let's begin.

Verify the retention period

To begin with, examine if the retention period you’ve set in your backup policy qualifies for LTR.

One year retention period

To enable LTR, you need at least one year of retention for any recovery point. Examples of retention periods that are eligible for LTR are as follows.

However, the following is not a valid retention period:

Based on your retention, whether or not your backup policy is eligible for LTR can be seen on the Create New Backup Policy page.
The following screenshot shows that the Enable Long Term Retention (LTR) option is disabled for this backup policy as the retention period is less than one year.

clipboard_eacd2b10bfebb39d4fe5be2df38ef4b15.png

However, if your retention period is greater than or equal to one year, you are eligible to enable LTR as shown in the following screenshot:

clipboard_ebf59d69451a67bcccc285a68f46d074b.png

Daily recovery points threshold

To enable LTR, ensure that the daily recovery points days must be less than the Warm recovery point threshold that you select.
The following screenshot shows that the daily recovery point limit exceeds the warm recovery point threshold.​

Duplicate backup policy

When creating a new backup policy for Windows/Linux Servers and NAS workloads, you can duplicate an existing backup policy as a template. All your existing settings are automatically added to the new backup policy. You can save time and reduce errors in creating a new backup policy.

πŸ“ Note
​ You cannot duplicate your old backup policies where the daily retention period exceeds the warm recovery point threshold. In the new LTR V2 the daily retention period must be less than the Warm Recovery pointthreshold.


Enable LTR

You can enable LTR either when creating a new backup policy or when editing an existing backup policy later.


πŸ“ Note
​ Long Term Retention (LTR) is available for Cloud and Druva GovCloud. However, it is currently not available for AWS Marketplace customers.

clipboard_e7282ba2cf76a7b3b059fc2c923133089.png

πŸ“ Note
​ In the case of Hyper-V and VMware,when LTR is enabled for a backup policy, file-level restore on cold recovery points is not supported.


Impact of changing threshold on existing recovery points

Increasing the threshold

You can change the number of days to keep recovery points in the warm tier from 15 to 30, 45, or 60 days.
For example, if the current setting is to keep recovery points in the warm tier for 15 days, all recovery points older than 15 days will move from warm to cold tier.
After you increase the threshold from 15 days to 45 days, the recovery points which are already in the cold tier will remain there. However, recovery points that are older than 45 days will now move to the cold tier.


πŸ“ Note
​If the threshold is increased for an existing backup, then a warning is displayed that increasing the threshold for existing backup sets will increase the credit consumption.


Decreasing the threshold

You can change the number of days to keep recovery points in the warm tier from 60 days to 15, 30, or 45 days.
Before changing the set threshold, all recovery points not older than 60 days will remain in the warm tier.
However, after you decrease the threshold from 60 days to 30 days, all recovery points that were created 30 days ago will be moved to the cold tier. In addition, eligible recovery points based on the new threshold, will now be migrated to the cold tier after 30 days.


πŸ“ Note
​If the threshold is decreased for an existing backup, then a warning is displayed that decreasing the threshold will have only XX days of warm recovery points.

Backup Policy - Update - Enabled

The backup policy where LTR was disabled earlier is updated with LTR enabled.

clipboard_e1985ae915627d2f573ef5d67d98d5e69.png

Backup Policy - Update - Disabled

The backup policy where LTR was enabled earlier is updated with LTR disabled.

clipboard_e84fff3e8c54c4b16d48dd355772743c6.png

πŸ“ Notes

  • In a backup policy if LTR is disabled, the Keep recovery points in warm tier field is not visible in the audit trail.

  • For a non-LTR customer, the LTR option is unavailable in the Backup policy configuration. Therefore, both LTR and Keep recovery points in warm tier fields are not visible in the audit trail.


Restore data from cold tier

At the time of restoration, data from the cold tier is retrieved, moved temporarily to the warm tier, and then restored. Once you initiate the restoration process, the data retrieval from the cold tier and its restore from the warm happen automatically. Warmed-up data is deleted from the warm tier after 10 days.

To restore the data from the cold tier (VMware as an example), perform the following steps:

  1. On the Management Console, select VMware from the Protect menu. Note that if the All Organizations menu is enabled, you have to first select an organization and then select VMware from the Protect menu.
    A list of all the registered VMware vCenter Servers and ESXi Hypervisors appears.
    ​

  9. For the Full VM Restore option, click Proceed to Restore.

Frequently Asked Questions (FAQs)

After increasing the threshold to keep recovery points in the warm tier, will the cold recovery points be converted to warm recovery points?

No. They will remain as cold recovery points, even though the threshold is increased.

After reducing the threshold to keep the recovery points in the warm tier, will more recovery points be converted to cold?

Yes. If recovery points are older than the set threshold, then they are eligible for the cold tier migration.

Will moving a backup set or virtual machine between policies with long-term retention (LTR) enabled result in additional charges for early deletion?

If the new policy has long-term retention (LTR) enabled and has the same or longer retention period than the existing policy, then no penalty will be incurred for moving the backup set or virtual machine.
