Backup copy targets retain copies of your backups on storage external to the appliance. Backup copies provide another layer of protection for your data and should be used for longer-term retention and disaster recovery. Retention options vary by backup copy target, but all targets enable you to define settings for long-term retention.
Backup copy management and administration procedures vary by target type. Once you have added a backup copy target:
• | See the applicable topic in Managing backup copy targets for details on working with the target you added. |
• | See to Creating backup copy jobs to start copying backups to the target. |
Note: The types of backup copy targets supported vary by Unitrends appliance model. For example, attached disk is not supported on Recovery Series appliances. When adding backup copy targets to an appliance, only supported types display in the Configure > Appliances > Backup Copy Targets > Add Target list.
Use these procedures to add backup copy targets to your Unitrends appliance:
You can use Unitrends Cloud Backup to store copies of your backups. To purchase this offering, go to http://www.unitrends.com/products/cloud-solutions/unitrends-cloud-backup.
To add a Unitrends Cloud backup copy target
1 | On the Configure > Appliances page, select your appliance. |
2 | Click the Backup Copy Targets tab. |
3 | Select Add Target > Unitrends > Unitrends Cloud. |
4 | Enter your Unitrends Cloud license string in the text box and click Submit. |
5 | Final configuration steps take place in the background and can take up to 15 minutes to complete. When complete: |
• | A Unitrends Cloud device has been added as a backup copy target. |
• | The Unitrends appliance name has been modified to include an additional 12 characters, required to uniquely identify this appliance in the Unitrends Cloud. |
6 | Fine-tune settings as described in To tune connection options. |
7 | Create a job to start copying backups to the Unitrends Cloud. For details, see To create a backup copy job for a Unitrends Cloud target. |
The procedures for adding a Unitrends appliance backup copy target vary by whether you are setting up a single target appliance or setting up a pair of appliances that will each store copies of the others backups (known as a cross-copy configuration). See one of the following for setup procedures:
Following is a summary of the steps required to use another Unitrends appliance to store copies of your backups. The Iinks provide detailed instructions for each procedure.
Note: Use these procedures to an appliance target that will only receive backup copies. To set up a pair of appliances that will each store copies of the others backups, see Setting up cross-copy between two Unitrends appliances.
Step 1: | Review the requirements in Preparing to add one Unitrends appliance backup copy target. |
Step 2: | Add the target appliance as described in To add one Unitrends backup copy target appliance. |
Before adding the backup copy target, verify that you have met appliance requirements, and seed the target appliance (optional).
For use as a backup copy target, an appliance must meet these requirements:
• | Must be a Unitrends Backup appliance or a Recovery Series model listed in the Recovery Series Appliance Family Datasheet. |
Notes:
• | Unitrends Backup appliances deployed to the following environments can be used either as a backup appliance or as a backup copy target (performing both roles is not supported): |
– | VMware |
– | Hyper-V |
– | Citrix XenServer |
– | Microsoft Azure |
• | Recovery Series appliances and Unitrends Backup Installable Software deployments can be used as both a backup appliance and a backup copy target, if desired. |
• | For Unitrends Backup, you must license and register the appliance. |
• | The appliance must have at least 200GB of available backup storage space. |
• | The configuration process creates a secure VPN tunnel. Be sure to use a network that is not in use in your environment. For example, if using netmask 255.255.255.0, the VPN tunnel must be on a dedicated subnet (default is 172.17.3.0). |
• | If one appliance is already managing the other (you are accessing both from one UI), then the manager appliance can be configured as the backup copy target only. To use the manager appliance as the source backup appliance, log in to the managing appliance and remove the managed appliance (as described in To remove a managed appliance) before configuring the backup copy target. |
For large data sets, Unitrends recommends that you seed the initial data set to the backup copy target by using removable media (disk or NAS). This seeding greatly reduces the time required to copy the first backups. For details, see the RapidSeed for Backup Copy Target Appliances document.
This procedure uses the following terms:
• | Backup copy target is the appliance that will be receiving and storing backup copies. |
• | Source backup appliance is the appliance running the local backups that will be copied to the target appliance. |
Do these steps on the backup copy target appliance
1 | Log in to the backup copy target appliance. |
2 | On the Configure > Appliances page, select the desired target appliance and click Edit. |
3 | On the Backup Copy tab, select Enable this appliance as a Backup Copy Target and enter the following information to configure a secure tunnel connection: |
• | Secure Network IP – This must be an unused network in your environment. |
• | Secure Netmask IP – The netmask associated with the secure network above. |
• | Secure Port – Port number to use for OpenVPN. |
4 | Click Save. |
Do these steps on the source backup appliance
1 | Log in to the source backup appliance. |
2 | On the Configure > Appliances page, select the source backup appliance. |
3 | Click the Backup Copy Targets tab. |
4 | Select Add Target > Unitrends > Unitrends appliance. |
5 | Enter the Host Name, Host IP address, User Name (optional), and Password (optional) of the backup copy target appliance, and click Save. |
6 | You receive a Connection could not be verified warning (unless you have previously installed your own custom security certificates on the target appliance.) As long as you trust your network configuration, you can safely click Continue. |
7 | After clicking Continue, it takes several minutes to configure the OpenVPN tunnel. Before continuing, wait for the confirmation message that the appliance has been added as a backup copy target. |
Return to the backup copy target appliance and do these steps
1 | Log in to the backup copy target appliance. |
2 | On the Configure > Appliances page, select the source appliance. The source has an ! icon and a Pending status. |
3 | Double-click the ! icon and enter the following: |
• | Select Allow backup copies to be sent from sourceAppliance. |
• | Select the storage device where backup copies will be stored on the target appliance. |
4 | Click Save. |
5 | Final configuration steps take place in the background and can take up to 20 minutes to complete. Configuration completes when you see the following: |
• | On the target's Appliances tab, the source appliance status has changed from Pending to Not Available. |
• | On the source backup appliance Backup Copy Targets tab, the status of the backup copy target has changed to Online. |
Once the above statuses have changed, you can use the target.
Notes:
• | To check the appliance status, reload the page to refresh the display. |
• | The Not Available status simply means the target appliance does not have credentials to manage the source beyond receiving its backup copies. |
6 | (Optional) Add management credentials to the source appliance: |
Note: By default, the backup copy target appliance does not manage backup copy source appliances. When the source appliance is not managed, backup copy jobs do not display on the Jobs > Active Jobs tab or on the Dashboard > Active Jobs tile. To view backup copy jobs from the target appliance, you must add management credentials for the source appliance.
• | Select the source appliance and click Edit, |
• | Check Enable Management of this appliance, supply User Name and Password credentials, and click Save. |
Return to the source backup appliance and fine-tune settings by adjusting connection options
For Unitrends Cloud and Unitrends appliance hot backup copy targets, you can adjust the following options for optimal performance in your environment:
Option | Description | Procedure | |||||||||
---|---|---|---|---|---|---|---|---|---|---|---|
Backup copy queue scheme |
The queue scheme determines the order in which the source appliance copies backups to the target:
|
See To configure connection options. | |||||||||
Backup copy concurrency | The Max Concurrent Backup Copies setting determines how many backups can be copied concurrently. While the default setting of two is adequate for most deployments, you may wish to increase the concurrency when you have enough WAN bandwidth to support more concurrent replications. | See To configure connection options. | |||||||||
Suspending backup copies | Use to stop sending backup copies from the source appliance. This option may become necessary when either your target appliance or the connection to your target becomes unavailable for an extended period of time. | See To configure connection options. | |||||||||
Backup copy bandwidth throttling |
If the WAN connection to your backup copy target is shared with general purpose Internet use during normal business hours, you may wish to throttle the amount of bandwidth that backup copies can use during these hours. Note: The bandwidth throttling setting limits the maximum amount of bandwidth the backup copy job can use. The amount of bandwidth available for the job is also effected by environmental factors, such as actual network throughput (which may be constrained by intermediate nodes between the source and target) and other backup copy job tasks, such as encryption and compression |
See To set bandwidth throttling. |
1 | Select Configure > Appliances. |
2 | Select the source backup appliance and click the Backup Copy Targets tab below. |
3 | Click Configure Bandwidth. |
4 | Choose the Connection Type that most closely matches your WAN bandwidth. |
5 | Click Add Schedule. |
6 | Choose a Throttle percentage and define the days of the week and times when this percentage will be used. |
The maximum bandwidth that backup copy jobs can use during the scheduled times is X percent of the Connection Type you chose in step 4 above.
7 | Click Save. |
8 | Repeat as necessary to create additional throttling schedules. |
1 | Select Configure > Appliances. |
2 | Select the source backup appliance and click Edit. |
3 | On the Backup Copy tab, modify settings. |
4 | Click Save. |
Create a job to start copying your backups. See To create a backup copy job for a Unitrends appliance target.
Use these procedures to set up cross-copy between two Unitrends appliances. In cross-copy configurations, each appliance acts as both a backup copy source and a backup copy target. This enables you to copy each appliance's local backups to the other appliance for added protection.
Note: To set up an appliance target that will receive backup copies only, see Adding one Unitrends appliance backup copy target.
Following is a summary of the steps required to set up cross-copy. The Iinks provide detailed instructions for each procedure.
Step 1: | Review the Cross-copy requirements. |
Step 2: | Configure cross-copy as described in To set up cross-copy. |
Both appliances must meet these requirements to use the cross-copy feature:
• | Must be running release 9.0.0-7 or higher. It is highly recommended that both appliances be running the same version. |
• | Must be a Unitrends Backup Installable Software appliance or a Recovery Series model listed in the Recovery Series Appliance Family Datasheet. |
Note: Unitrends Backup appliances deployed to the following environments cannot be used for cross-copy: VMware, Hyper-V, Citrix XenServer, or Microsoft Azure.
• | The appliance must have at least 200GB of available backup storage space. |
• | The configuration process creates a secure VPN tunnel. Be sure to use a network that is not in use in your environment. For example, if using netmask 255.255.255.0, the VPN tunnel must be on a dedicated subnet (default is 172.17.3.0). |
• | If one appliance is already managing the other (you are accessing both from one UI), you must log in to the managing appliance and remove the managed appliance (as described in To remove a managed appliance). Cross-copy cannot be configured if either appliance is managing the other. |
For large data sets, Unitrends recommends that you seed the initial data set to the backup copy target by using removable media (disk or NAS). This seeding greatly reduces the time required to copy the first backups. For details, see the RapidSeed for Backup Copy Target Appliances document.
To set up cross-copy, follow the steps in this procedure carefully. You must complete the steps in order and be sure to run each from the correct appliance. This procedure uses the terms appliance1 and appliance2 to identify the appliance where each step must be run.
Log in to both appliance UIs
To set up cross-copy, you will switch between the appliance UIs. Log in to both appliance UIs. Make a note of which appliance you will use as appliance1 and which appliance you will use as appliance2.
Do these steps on appliance1
1 | On the Configure > Appliances page, select appliance1 and click Edit. |
2 | On the Backup Copy tab, select Enable this appliance as a Backup Copy Target and enter the following information to configure a secure tunnel connection: |

Use this procedure to add an eSATA or USB backup copy target. For eSATA and USB devices, you must initialize new drives before using them for the first time. This permanently deletes any existing data and formats the drives.
Additional considerations for using a device with multiple drives:
• | All drives attached to a single appliance must have equal capacity. Drives may be of varying capacity if they are attached to different appliances. |
• | Within the backup copy target, all drives attached to a single appliance are treated as one logical device. When you add a multi-drive device and initialize the drives, the appliance formats them as a single unit. Data is then written across all drives as if they are one larger drive. Once you copy backups to the device, these drives must be treated as a single entity. You must remove them as a set and, to recover data, you must insert all drives in the set back into the eSATA or USB device so the appliance can read and import backup data. If you separate a drive from the set, all data is lost. |
1 | Connect the eSATA or USB device to the Unitrends appliance and power it on. For details, see the instructions you received with the device. |
2 | Log in to the appliance UI. |
3 | On the Configure > Appliances page, select the source backup appliance. |
4 | Click the Backup Copy Targets tab below. |
5 | Click Scan For Media. |
• | The appliance discovers the device and it displays on the Backup Copy Targets tab. |
• | The device displays as Type eSATA or USB and its status is Offline. |
6 | Do one of the following: |
• | If your drive(s) contains backup copies from another Unitrends appliance, select the device on the Backup Copy Targets tab and click Enable. The appliance brings the device online and imports reference information about those backup copies. |
• | If your drive(s) does NOT contain backup copies from another Unitrends appliance, select the device on the Backup Copy Targets tab and click Erase. The appliance erases any existing data and formats the disk(s). |
7 | The target is ready for use. Create a job to start copying your backups, as described in To create a backup copy job for an eSATA or USB target. |
Note: The backup copy job mounts the media, writes the copy, then unmounts the media. On the Backup Copy Targets tab, the device remains Offline when the media is not mounted. The device is automatically brought Online when a copy job runs.
Following is a summary of the steps required to add a tape backup copy target. The Iinks provide detailed instructions for each procedure.
Step 1: | Review the requirements in Preparing to add a tape backup copy target. |
Step 2: | Connect the tape device as described in To connect the tape device. |
Step 3: | Add the tape backup copy target to the appliance and configure it as described in Configuring the tape device on the Unitrends appliance. |
Before adding the tape backup copy target, review these requirements and considerations.

You can use cloud storage managed by select providers to store copies of your backups. Use this procedure to add cloud storage to your appliance as a backup copy target.
Cloud storage must meet these requirements to be used as a backup copy target:
• | You must have an account with one of the following cloud storage providers: Google Cloud Storage Standard, Google Cloud Storage Nearline, Amazon S3, or Rackspace. For details about creating an account and purchasing storage, see KB 3649. |
• | For bucket names, only the following characters are supported: upper and lowercase letters, numbers, dots, and dashes. Buckets with names containing other characters cannot be added to a Unitrends appliance. |
• | For Amazon S3, Google Cloud Storage Standard, and Google Cloud Storage Nearline, you can use existing buckets that follow the supported naming conventions identified above. However, we recommend that you create unique folders for your Unitrends data. |
• | Amazon S3’s Reduced Redundancy Storage (RRS) option is not supported. |
You must enter the following account information when adding a cloud backup copy target to the appliance:
• | Credentials for the storage bucket that you are adding to the appliance. |
Note: These are the credentials you use to access the particular bucket or container that you are adding to the appliance, and not the username and password you use to log in to your storage provider account. If you do not know these credentials, contact your storage provider. Unitrends does not have access to this information.
• | Name of the cloud storage provider. |
• | Name of the bucket that you are adding to the appliance. |
Additional considerations:
• | Accounting and billing management for your cloud storage occur between you and the storage provider. You cannot manage your cloud storage account from the appliance’s UI, and Unitrends cannot answer questions about this account. You must contact your provider with any questions you have about your cloud storage account. |
• | It is extremely important that you understand the amount of data you are copying and the related charges from your cloud storage provider. To manage the amount of space you are using in cloud storage, you should specify a storage threshold. |
• | Sending backup copies to the cloud does not require any special network configurations. Just add a backup copy cloud target to the appliance and create backup copy jobs. |
• | The speed at which backup copies can be sent to the cloud depends on a number of factors, including memory and network bandwidth. We recommend that you test a small backup copy to determine the speed prior to sending larger backup copies to the cloud. |
• | When recovering backup copies from the cloud, the cloud backup copy target can be attached to any Unitrends appliance. You do not have to recover to the original appliance. |
• | If you add a backup copy target and the appliance recognizes backups on it, those backups are added to the Backup Catalog and are available for import. |
It is extremely important that you monitor the amount of backup data that your Unitrends appliance is copying to the cloud because cloud storage providers charge based on the amount of storage you use. When adding cloud backup copy target to the appliance, you can specify a storage threshold equal to the maximum amount of space the appliance can use to store backup copies in the cloud storage bucket.
You can monitor the amount of data in your cloud storage from the Storage tile on the Dashboard or from the Configure > Appliance > Backup Copy Targets page.
About the storage threshold for cloud backup copy targets
The storage threshold setting for cloud backup copy targets is intended to aid in managing the total amount of data you are copying to the cloud. The user-defined storage threshold functions as a maximum amount of data the appliance can write to the cloud bucket.
Note that there are instances when backup copy jobs can use slightly more storage space than the storage threshold you specified. When you initiate a backup copy job, the appliance estimates the amount of space needed for the job, and certain factors can cause it to underestimate. To avoid unexpected charges from your cloud storage provider, it is highly recommended that you develop a policy for managing the amount of backup data that you copy to the cloud in addition to setting a storage threshold.
The storage threshold can be increased or decreased at any time, and changes are applied to all subsequent jobs copying backups to the bucket. If you increase the storage threshold, your storage provider will bill you for the additional storage space you are using.
Note that decreasing the threshold to a value that is less than the amount of space currently used to store backup copies can result in the deletion of backup copies. The next time the job runs, the appliance recognizes that the amount of data on the backup copy target is greater than the storage threshold and invokes your selected behavior: either deleting older backups to free space or failing the job. If you select to delete older backup data to free space for the job, backup copies exceeding the new storage threshold are purged the next time the job runs. Backup groups are still recognized in backup copies, and backups are deleted as a group beginning with the oldest backup copies. If you chose to fail the backup copy job and send an alert, your new backup copies are not written to the cloud and an alert notifies you of this failure.
1 | On the Configure > Appliances page, select your appliance. |
2 | Select the Backup Copy Targets tab. |
3 | Click Add Target > Cloud. |
4 | Enter a Name for the cloud storage. |
5 | Select the storage provider in the Cloud Storage drop-down. |
6 | Enter the bucket’s name in the Storage Path field. |
To create a sub-folder within the bucket, add a forward slash followed by the name of the new folder and another forward slash. For example: If your bucket is named mybackup and you want to create a new sub-folder within that bucket called myfolder, enter: mybackups/myfolder/
7 | Enter the required credentials. These vary by storage provider: |
Note: Be sure to enter the credentials you use to access the particular bucket that you are adding to the appliance. These credentials are not the same as the username and password you use to access your storage provider account.

8 | (Optional) We recommend enabling and setting a storage threshold. This functions as the maximum amount of data the appliance can copy to the cloud. For more information, see Managing the amount of data copied to a third-party cloud target. |
9 | Click Save. |
10 | The cloud target is added to the appliance. |
Cloud storage is mounted only while a backup copy job is running. At other times, cloud storage is unmounted. This is the recommended approach to prevent issues that may occur if the connection to cloud storage is interrupted. If desired, you can configure a persistent connection as described in To disable automatic cloud mount/unmount below.
Various external network events can interrupt the connection to cloud storage. To prevent issues that may occur if this connection is interrupted, cloud storage remains unmounted until a backup copy job runs. The job mounts the cloud storage, copies data to the target, and unmounts the storage. If desired, you can configure the appliance to maintain a persistent connection to the cloud storage target, as described here:
1 | On the Configure > Appliances page, select the appliance and click Edit. |
2 | In the Edit Appliance dialog, click Advanced and select General Configuration. |
3 | Change the CloudHook UnmountAfter setting to 0 and click Save |
Use this procedure to copy backups to attached disk storage. This target type is supported only for Unitrends Backup appliances deployed on Hyper-V, VMware, or XenServer.
Before adding the backup copy target, add an attached disk to the Unitrends Backup VM or to external storage attached to the Unitrends Backup hypervisor. To provide redundancy, Unitrends recommends that backup copy storage be on a different datastore or different type of storage than the backup storage. Choose from the following methods to add a disk:
• | For Unitrends Backup on VMware, add a VMDK disk to the Unitrends Backup VM by using the ESXi host. See one of the following VMware documents for instructions: |
– | vSphere 5.1: Create a Virtual Disk in vSphere Client 5.1 |
– | vSphere 5.5: Create a Virtual Disk in vSphere Client 5.5 |
– | vSphere 6.0: Create a Virtual Disk in vSphere Client 6.0 |
• | For Unitrends Backup on Hyper-V, add a virtual disk to the Unitrends Backup VM by using the Hyper-V host. Unitrends recommends that you use a VHD(X) disk and that you add the disk to the SCSI controller. See the following Microsoft documents for instructions: |
– | To create a virtual hard disk |
– | To add a hard disk to a virtual machine |
• | For Unitrends Backup on XenServer, add a VHD disk to the Unitrends Backup VM by using the XenServer host. Unitrends recommends that you add the disk to the SCSI controller. |
• | Add a LUN to an external SAN and expose it to the Unitrends Backup VM. Then go to the host and add a new virtual disk to the VM using storage on the LUN you added. |
• | Connect a NAS share to the Unitrends Backup VM using the NFS or CIFS protocol. Then go to the host and add a new virtual disk to the VM using storage on the share you added. |
1 | Attach a disk to your Unitrends Backup VM as described above in Preparing to add an attached disk backup copy target. |
