Clone Volumes

This guide covers cloning storage volumes to create exact copies with all data preserved. Cloning creates a new volume with identical data from the source volume.

Coming March 2026: Clone operations will be available in Advanced Tier regions (FINLAND-1/2/3) when they launch. Legacy Tier (CANADA-1) does not support cloning.

Prerequisites

Before cloning, ensure you meet the general volume prerequisites.

Clone-Specific Requirements:

Source volume in advanced tier region (FINLAND-1/2/3)

Volume status: Available OR Attached to SHUTOFF instance

Clone destination: Same region as source (cross-region not supported)

Unique name for clone within target region

Important: Cloning is only available in advanced tier regions. Legacy regions (CANADA-1) do not support cloning.

Clone Configuration

Property	Behavior	Options
Name	Required unique name	Default: `{source}-clone`. Rules: 3-30 chars, alphanumeric + `_-`
Size	Inherited from source	Cannot change during clone. Use resize after.
Volume Type	Selectable	Keep source type OR switch between NVMe/HDD
Region	Same as source	Cross-region not supported
Bootable	Inherited from source	Matches source volume bootable status

Volume Type Options

NVMe — High-performance NVMe storage ($219.00/TB/month USD)

Low latency, high IOPS

Best for databases and I/O intensive workloads

HDD — Cost-effective magnetic storage ($58.40/TB/month USD)

Higher latency, lower cost

Best for backups, archives, and sequential workloads

Choose based on your performance vs. cost requirements.

Cloning a Volume

Step 1: Select Source Volume

Go to barrack.ai/volumes

Use region dropdown to filter volumes. Source volume must be in an advanced tier region.

Find the volume you want to clone. Click the info icon (ℹ️) on the volume card to view details.

Step 2: Verify Clone Eligibility

Check source volume status and instance state.

Eligible Volumes:

Status: "Available" (not attached to any instance)

Status: "Attached" with instance status: "SHUTOFF"

Ineligible Volumes:

Attached to any instance that is not in SHUTOFF status (shut down instance first)

In "Creating" state (wait for completion)

Located in legacy region CANADA-1 (not supported)

Step 3: Initiate Clone Operation

In the volume details modal:

Click "Clone" button in the Advanced Operations section

Clone modal opens with pre-filled information

Pre-filled Data:

Clone name: {source-volume-name}-clone

Size: Inherited from source (read-only)

Region: Source volume region (read-only)

Volume type: Source volume type (modifiable)

Step 4: Configure Clone Settings

Clone Name:

Edit the suggested name if desired. Name must be:

Unique in target region

3-30 characters

Letters, numbers, hyphens, underscores only

Cannot start/end with hyphen or underscore

Volume Type:

Select volume type for clone:

Keep source type OR

Change to different type (NVMe/HDD)

Pricing Information:

The modal displays:

Per TB monthly rate for selected type

Total monthly cost based on volume size

Currency (USD/EUR/INR based on account)

Step 5: Confirm Clone

Review configuration and click "Clone Volume" button.

Clone Process:

System validates source volume status

System checks instance state (if attached)

System verifies sufficient credits

System validates region restrictions

System checks name uniqueness

Barrack creates volume clone

New volume appears in volumes list

Billing starts for cloned volume

Clone operation is initiated immediately. Completion time depends on volume size. The cloned volume will appear in your volume list once the operation completes.

Step 6: Verify Clone

After clone completes:

Volume List Updates:

New volume appears with clone name

Status shows "Available"

Size matches source volume

Selected volume type displayed

Same region as source

Clone Data:

All data from source volume preserved

Filesystem intact

Files accessible immediately after attachment

Validation

The system validates before proceeding:

Volume Checks:

Exists and belongs to your account

Status is Available or Attached to SHUTOFF instance

Located in advanced tier region (not CANADA-1)

Size within supported limits

Instance Validation (if attached):

Instance status must be SHUTOFF

Any other instance status will be rejected

Name & Region:

Clone name is unique in target region

Target region matches source region

Follows naming rules (3-30 chars, alphanumeric + _-)

Account Status:

Sufficient credits for cloned volume billing

Profile complete with minimum balance

Post-Clone Status

Cloned Volume

Status:

Initially "Creating" during clone process

Changes to "Available" when ready

Ready for attachment to any instance

Properties:

Same size as source volume

Selected volume type (NVMe or HDD)

Bootable status inherited from source volume

Same region as source

Data:

Complete copy of source volume data

All files and filesystem preserved

No data loss or corruption

Independent from source volume

Source Volume

Source volume status unchanged

Data remains intact

Still available for use

Can be cloned again if needed

Billing Impact

Cloned Volume Billing:

Billing starts immediately after creation

Hourly rate based on size and type

Independent billing from source volume

Same rates as creating new volume

Source Volume Billing:

Continues unchanged

No impact from clone operation

Pricing

Cloned volumes use the same pricing as new volumes.

Advanced Tier (NVMe):

Currency	Rate
USD	$219.00/TB/month
EUR	€255.50/TB/month
INR	₹21,900/TB/month

Advanced Tier (HDD):

Currency	Rate
USD	$58.40/TB/month
EUR	€73.00/TB/month
INR	₹5,840/TB/month

Billing: Starts immediately after clone creation. Charged hourly based on size and type. Independent billing from source volume.

Examples:

Clone 500GB NVMe volume: (500 ÷ 1024) ×

219.00 =

106.93/month

Clone 2TB HDD volume: (2048 ÷ 1024) ×

58.40 =

116.80/month

Troubleshooting

Volume can only be cloned when available or attached to shut off instance

Cause: Source volume attached to an instance that is not in SHUTOFF status.

Fix:

Navigate to instances page

Shut down the attached instance

Wait for SHUTOFF status

Retry clone

Verify: Instance shows "SHUTOFF" before cloning.

Cross-region cloning not supported

Cause: Attempting to clone to a different region.

Fix: Clone must be in the same region as source. This is a platform restriction for data consistency and performance.

Options:

Clone in source region, then manually transfer data

Create new volume in target region and copy data

Cross-region cloning may be added in future updates.

Cloning only supported for advanced tier regions

Cause: Source volume in CANADA-1 (legacy region).

Fix: Cloning is only available in FINLAND-1, FINLAND-2, and FINLAND-3.

Options:

Use advanced tier volumes for cloning

Create new volume and manually copy data

Consider migrating to advanced tier regions

Clone Button Disabled

Common Causes:

Volume attached to an instance that is not SHUTOFF → Shut down instance first

Volume in "Creating" state → Wait for provisioning to complete

Volume in CANADA-1 region → Cloning not supported

Hover over the disabled button to see the specific reason in the tooltip. Address the issue before retrying.

Best Practices

Before Cloning:

Verify source data is current and backed up

Ensure sufficient credits for new volume billing

Choose volume type (NVMe vs HDD) based on performance needs

Plan unique naming convention for clones

Shut down attached instance if required

During Clone:

Don't modify source volume during clone process

Don't delete source volume during clone process

Wait for completion before attaching

Monitor account credits for new volume charges

After Clone:

Verify clone status shows "Available"

Test data accessibility after attachment

Verify all files present and accessible (ls -lah)

Check filesystem integrity (df -h)

Update documentation with clone details

Consider deleting source if no longer needed

Next Steps

Verify Clone — Check volume appears in volumes list with "Available" status and correct size/type.

Attach to Instance — Navigate to cloned volume, click "Attach", select target instance (SHUTOFF), and confirm. See Attach Volumes for detailed instructions.

Mount in OS — Start instance, SSH in, identify device (lsblk), and mount volume (mount /dev/vdb /mnt/data). See Attach Volumes - Instance Configuration for OS-level mounting.

Verify Data — Check all files present, verify filesystem integrity, and test file access.

Update Applications — Update application configurations to use new volume if replacing original.

Support

For clone assistance, contact [email protected]. Include: source volume ID/name, clone name attempted, error messages received, request ID (if applicable), and region.

Related: Resize Volumes — Increase cloned volume size after creation. Requirements: volume status Available or Attached, new size larger than current, advanced tier region only.
