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.

Prerequisites

Before cloning, ensure you meet the general volume prerequisites.

Clone-Specific Requirements:

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

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

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	Always non-bootable	Clones are data volumes only

Volume Type Selection

NVMe - High-performance NVMe storage ($0.30/GB/month)

Low latency, high IOPS

Best for databases and I/O intensive workloads

HDD - Cost-effective magnetic storage ($0.08/GB/month)

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

Navigate to Volumes Page

Go to barrack.ai/volumes

Select Region

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

Locate Volume

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

Step 2: Verify Clone Eligibility

Check source volume status and VM state:

Eligible Volumes:

Status: "Available" (detached)

Status: "Attached" with VM Status: "SHUTOFF"

Ineligible Volumes:

Attached to ACTIVE instance (shut down first)

Attached to CREATING/HIBERNATED instance

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 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:

Modal displays:

Per GB 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

Processing Time:

Clone operation typically completes within 2-5 minutes depending on volume size. Larger volumes take longer.

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

View Pre-Clone Validation Checks

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 is SHUTOFF

Not ACTIVE, CREATING, or HIBERNATED

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

Common validation errors are covered in Troubleshooting below.

Post-Clone Status

After successful clone:

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)

Non-bootable data 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

Unchanged:

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

Troubleshooting

Clone-Specific Errors

Error: Volume can only be cloned when available or attached to shut off VM

Error: Cross-region cloning not supported

Error: Cloning only supported for advanced tier regions

Clone Button Disabled

Common Errors

For authentication, credits, profile, and session errors, see Common Volume Errors.

Pricing

Cloned volumes use same pricing as new volumes:

Advanced Tier (NVMe):

$0.30/GB/month (USD)

€0.35/GB/month (EUR)

₹30.0/GB/month (INR)

Advanced Tier (HDD):

$0.08/GB/month (USD)

€0.10/GB/month (EUR)

₹8.0/GB/month (INR)

Billing:

Starts immediately after clone creation

Charged hourly based on monthly rate

Independent billing from source volume

Examples:

Clone 500GB NVMe volume:

Monthly cost: 500GB ×

0.30 =

150/month

Hourly rate:

150 \div 730 =

0.21/hour

Clone 2000GB HDD volume:

Monthly cost: 2000GB ×

0.08 =

160/month

Hourly rate:

160 \div 730 =

0.22/hour

Best Practices

Cloning 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 (2-5 minutes typical)

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

After cloning volumes:

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

Email Support

Contact support for clone assistance. Include source volume ID/name, clone name attempted, error messages received, request ID (if applicable), and region.

Resize Volumes

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