ALTO tiers explained (how to reduce overages)



This article covers sizing tiers for ALTO devices and the recommended solutions to reduce overages.

Background of Tiers

Here is some information regarding the different ALTO devices and their capacity for the total offsite storage space:

  • LT150
    Up to 150GB of total offsite storage space
  • LT250
    Up to 250GB of total offsite storage space
  • LT500
    Up to 500GB of total offsite storage space

Any of the above tiers will be billed at the next largest tiers if exceeded at the monthly billing cycle at the end of the month.

  • LT1000
    Up to 1000GB of total offsite storage space

Any overages will be applied monthly based on how much you exceed this limit. For further information on this please contact your Sales Representative. 

Monitoring the Offsite Storage

To monitor and check the offsite storage, follow these steps:

1. Log into the Partner Portal.

2. From there, click the Status menu, and choose BCDR Status (Figure 1).

Figure 1 - Device Status

3. From the devices tab, find your device in the right hand device list, and click on it.

4. This will populate a left hand device pane. From this pane, click on the Advanced tab, and find the Offsite Audit hyperlink labeled Run Audit (Figure 2).

5. Click on the link to generate an offsite report for this device.

6. The audit report will be visible for a period of time.

Ways to Free Up Space and/or Reduce Overages

Due to the way Datto devices store data, the inverse chain does not allow removing points in the middle of the backup chain to free up space. Each point relies on other points in order to provide reliability in the data. The space used by each recovery point snapshot changes with the distribution of data change throughout all of the data set.

For more information about how the Datto devices store data, check out the following article:

Managing Recovery Points

The fastest way to reduce your overages is to manually delete the offsite points yourself, starting with your oldest recovery points. To do this, log into the Web UI of the Datto and go to the Protect tab, find your Agent and choose Manage Recovery Points.

In order to do this, follow these steps:

1. Log into the web interface of the Datto device.

2. Go to the Protect tab.

3. Find the agent needed to do this and select Manage Recovery Points.

4. Scroll to the bottom of the page and click on each blue Delete Cloud button up to the point where it's been determined the large change occurred (Figure 3).

Adjusting Retention Settings

Retention settings can also be a great help to manage space. For more information about how offsite retention settings work, check out this article:

To access these settings, follow these steps:

1. Log into the web interface for the device.

2. Select the Protect tab.

3. Find the agent needed, and select Configure Agent Settings.

4.  In the Configure Agent Settings section, adjust the Offsite Retention interval for Delete Offsite (Figure 4).

Note: The offsite retention can automatically prune 100 points a night per dataset (the "agent"). If there is replication of numerous points to the cloud, there may be need for a wait to allow the replication to process. If this becomes a problem, please contact Datto Technical Support to have the process forced multiple times through the back end. Alternatively, you may need to submit an Offsite Prune Request.
