SIRIS, ALTO, and NAS: Reverse RoundTrip overview



This article describes the Reverse RoundTrip process, which allows for physical data retrieval from the Datto Cloud.


  • Datto Reverse RoundTrip


A Reverse RoundTrip lets you retrieve data from the Datto Cloud by having the Datto Datacenter copy it to a portable drive that we can ship to a location of your choice.

Important information

  • Reverse RoundTrips are a paid service. See this section of this article for base service fees. Datto waives these fees in a disaster recovery scenario.
  • Ask Datto Technical Support if a Reverse RoundTrip is the best solution for you. In many scenarios, a Reverse Send is a faster method. A Reverse Send is a manual process that Datto Technical Support can use to send incrementally-changed data from an offsite virtualization down to your device.
  • To obtain specific pricing for a Reverse RoundTrip and to better understand if a Reverse RoundTrip is the best solution for you, contact your Datto Sales Executive.
  • Reverse RoundTrips are not available for Cloud Continuity.

Ordering a Reverse RoundTrip

To order a Reverse RoundTrip, use the Reverse RoundTrip Request Form. Submitting this form creates a Technical Support ticket with all of the information below:

File format


ZFS is the smallest, fastest file format available for Reverse RoundTrips. It is also the native format in which Datto houses data.

  • ZFS allows for any restore operation when sent as a USB drive and connected to a Datto device.
  • ZFS saves space by storing only the changed data for each recovery point, instead of the entire image. For example, if you request 3 points with 200 GB, 225 GB, and 275 GB of space consumed, then you will only need a Reverse RoundTrip for about 300 GB of data.


A NAS unit, housing Reverse RoundTrip data in ZFS, is also available as a standalone solution.

Datto recommends ZFS or ZFS-NAS, as either solution reduces time, money, and effort for all parties.

Image export (VHD, VMDK)

Datto can send Image exports on any of the above options. Image exports contain full disk images rather than a file directory structure.

  • Image export is the largest restore option, and as such, will typically cost the most (unless done as a local image export in ZFS format).
  • Image export is the most direct method when restoring to a hypervisor.
  • You can request VMDK or VHD image formats depending on your hypervisor.


Datto recommends ZFS format as it is the smallest and least expensive storage method. However, upon request, Datto can export specific directories or files to the Reverse RoundTrip device in the native file system format. When submitting your request, specify the device's file system (typically NTFS, ext4). 

Image Export or Directory formats will be considerably larger than ZFS format because the estimated size is the total protected size of the agent, multiplied by the number of backup points requested. For example, if an agent with an average protected size of 1 TB, and 20 GB of data change per backup, with 12 backup points requested, the total capacity will be 1 TB x 12 = 12 TB.

Datto does not support RoundTrips on volumes with NTFS deduplication or NTFS compression.

Drive options

  • Encrypt your RoundTrip drive? This option lets you specify if a drive is encrypted or unencrypted. If encrypted, only the Datto appliance associated with this request can decrypt the drive.
  • Keep (purchase your RoundTrip) drive? You can buy the drive used in the RoundTrip process for a fee. Otherwise, you will need to return it to Datto.

Desired date range

Select agent volumes

Figure 1: Select agent volumes

You can select any volume associated with agents that have been replicated to the cloud. If you only want specific directories or files, choose Directory as your File Format and relay the desired information in Optional - Details on specific files.

Optional - Details on specific files

You can use this field to relay any additional details or concerns to support when submitting your request.

Shipping and technical contact details

Submitting a request will open a ticket with Datto Technical Support. Provide a valid e-mail address for the contact associated with your request.

Provide a valid shipping address. We ship via UPS and can provide transportation charges before shipment upon request.

You can relay any optional instructions (for shipping, support, etc.) in the Optional Instructions field.

Datto-provided RoundTrip vs. partner-provided RoundTrip

You can choose to provide the drive for the Reverse RoundTrip. Datto recommends that we provide the necessary equipment for the fastest and most reliable data retrieval process. See our SIRIS, ALTO, and NAS: Using your own storage device as a RoundTrip drive article to learn more about using your own drive.

Reverse Round-Trip process

1. Technical Support sees the ticket and reaches out to the partner for a brief consultation

This consultation is to verify the specifics of the request and to make sure it will meet the needs of the partner.

2. Technical Support confirms that you have provided all required information

If you are sending Datto a storage device, you need to update the support ticket with the tracking number so that our RoundTrip team can track the incoming shipment.

If you are providing the storage device, you need to ship the unit to the designated data center for your location (see below). Datto is not responsible for costs incurred in shipping partner-provided units to the data centers.

3. Technical Support engages Cloud Support

After preliminary setup, Cloud Support synchronizes the data as requested. Cloud Support will provide an estimated cost for the Reverse RoundTrip and do a final check on all information. The table below outlines the time frames in which you can expect these data syncs to complete:

4. RoundTrip Support ships the RoundTrip unit  

Datto ships the Reverse RoundTrip unit to the address provided on the request form. All orders are shipped UPS Overnight. Make sure that you keep everything in the box, especially the Datto-provided return shipping label.

5. RoundTrip Operations bills for syncing service fees

Once Datto ships the drive, RoundTrip Operations bills the partner for the service fees. We base this charge on the amount of data synced to the RoundTrip device, not the size of the device. Base service fees are $50 for the first 2 TB block of data synced and $50 for each additional 1 TB block of data synced.

  • Syncing 0.1 TB - 2.0 TB costs $50
  • Syncing 2.1 TB - 3.0 TB would cost $100
  • Syncing 3.1 TB - 4.0 TB would cost $150, etc.

The invoice is submitted as Awaiting Reseller Approval in the Partner Portal so that you can associate a credit card with the invoice in the checkout cart.

You have the option to sync data back to the Datto appliance

Datto Technical Support can assist in copying the Reverse RoundTrip data back to a Datto appliance. If you have any encrypted agents or shares, and we are restoring encrypted data from our cloud servers, the process is similar to the above procedure. However, before repairing agent communication after the sync, Datto downloads algorithm information to the appliance, allowing you to enter the encryption passphrase. After entering the passphrase, you can pair the agent and resume backups.

You can either return the Reverse RoundTrip unit to Datto or pay to keep it

You must return the Reverse RoundTrip in the original packaging that you received it in. Packaging consists of the box, packing materials, USB cables, and power supply (if applicable). If you wish to keep the Reverse RoundTrip unit for archival purposes, Datto will charge a replacement fee (see the tables below).

You must return the Reverse RoundTrip unit within fourteen (14) days of delivery. If you do not return the Reverse RoundTrip within four weeks (28 days) of delivery, Datto will consider the drive late and will send a notification. If Datto does not receive a Reverse RoundTrip unit back within eight weeks (56 days) of delivery, Datto will bill you for the full replacement cost of the Reverse RoundTrip.
