Ubuntu Backup and Recovery with Catalogic DPX
Catalogic DPX protects Ubuntu servers with file-level backup, block-level backup, bare metal recovery, and centralized recovery management. Use DPX Client protection for physical Ubuntu systems and virtual Ubuntu servers, or protect Ubuntu VMs through agentless VMware and Microsoft Hyper-V workflows where those hypervisors are used.
- DPX Client support for Canonical Ubuntu 18.04, 20.04, and 22.04 LTS
- File-level and block-level backup for supported Ubuntu systems
- Bare metal recovery for full-system restore scenarios
- Agentless VM protection for VMware and Microsoft Hyper-V environments
- Immutable backup storage with vStor and ransomware detection with GuardMode
Verified Ubuntu support in DPX for 2026
Current DPX compatibility data lists Canonical Ubuntu 18.04, 20.04, and 22.04 LTS for DPX Client protection. Newer Ubuntu releases, including Ubuntu 24.04 LTS, should be validated against the current DPX Compatibility Matrix or with Catalogic Product and Support before production rollout.

DPX support does not replace Canonical operating system lifecycle management. Customers should keep Ubuntu systems under an appropriate Canonical support or security maintenance plan.
For Ubuntu systems on hypervisors outside the documented DPX agentless paths, position DPX Client protection inside the guest as the supported coverage angle unless Product has validated a separate agentless integration.
One DPX platform for Ubuntu physical servers and virtual machines
DPX protects Ubuntu through two practical deployment models. For physical servers and many virtualized Ubuntu workloads, install the DPX Client on the Ubuntu system and register it with the DPX Master Server. This enables file-level backup, block-level backup where prerequisites are met, and bare metal recovery for supported configurations. For Ubuntu VMs running on VMware or Microsoft Hyper-V, DPX can also protect the VM through agentless hypervisor workflows.
- Protect physical Ubuntu servers with the DPX Client
- Protect Ubuntu VMs with the DPX Client when guest-level backup is preferred
- Use agentless VMware backup for Ubuntu VMs on supported VMware environments
- Use agentless Hyper-V backup for Ubuntu VMs on supported Microsoft Hyper-V environments
- Store backups on vStor, disk, tape, or supported object storage workflows
- Recover individual files, volumes, or full systems based on the selected backup method
Backup capabilities for Ubuntu servers
DPX gives infrastructure teams several recovery paths for Ubuntu, from file restore to full-system recovery. The right method depends on whether the workload is physical, virtual, VMware-based, Hyper-V-based, or deployed on another platform where guest-level protection is the right fit.
- File-level backup and restore for supported Ubuntu systems
- Block-level backup for supported Ubuntu LVM configurations
- Block-level incremental protection to reduce backup time and infrastructure load
- Selective restore and volume restore for block backup workflows
- Bare metal recovery for rebuilding supported Ubuntu systems after major failure
- Centralized job scheduling, monitoring, reporting, and policy management
- Backup storage options for local recovery, long-term retention, and offsite resilience
Recommended Ubuntu protection patterns
Use these patterns to identify the right DPX architecture without overstating platform support.
Physical Ubuntu servers
Install the DPX Client on the Ubuntu server, register it with the DPX Master Server, and configure file-level or block-level backup based on the workload and storage layout.
Ubuntu VMs on VMware
Use DPX agentless VMware backup where VM-level protection is the goal. This reduces guest-agent management and supports VMware-based recovery workflows.
Ubuntu VMs on Microsoft Hyper-V
Use DPX agentless Hyper-V backup for supported Hyper-V environments, or deploy the DPX Client in the guest when block-level guest protection is required.
Ubuntu on other hypervisors
Use DPX Client protection inside the Ubuntu guest unless a separate DPX integration is validated for that platform. This is the safest positioning for platforms not listed in the DPX agentless compatibility data.
Ubuntu file servers
Use file-level backup for directories, user data, configuration files, and general Linux file protection. Add GuardMode where ransomware behavior monitoring is required.
Ubuntu application hosts
Use DPX Client protection for Ubuntu systems hosting applications, middleware, or custom services. Coordinate application consistency through scripts, maintenance windows, or workload-specific procedures where required.
Granular restore
DPX supports targeted file recovery for Ubuntu workloads so teams can restore files and directories without rebuilding the entire server. This is the preferred recovery path for accidental deletion, configuration rollback, and operational recovery after a limited data issue.
Use this for:
- Deleted or overwritten files
- Configuration rollback
- User data recovery
- Recovery from a known clean restore point
System recovery
For larger incidents, DPX supports block-level restore and bare metal recovery for supported Ubuntu configurations. This helps recover from server loss, storage failure, or ransomware events where rebuilding the system is faster and safer than manual repair.
Use this for:
Implementation note: Bare metal recovery has documented limitations. The target physical disk must be less than 2 TB, and configurations using multipath are not compatible.
- Failed servers
- Corrupted operating system volumes
- Major storage failure
- Full recovery after a destructive incident
Cyber-resilient recovery
Add ransomware detection and immutable storage to Ubuntu backups
Ubuntu backup is not only about restore points. Ransomware and destructive attacks can corrupt production data before a backup job runs. Catalogic GuardMode adds ransomware and anomaly detection designed for backup teams, monitoring filesystem behavior such as suspicious extensions, rapid renames, decoy file modification, high-entropy files, and abnormal long-running modification patterns. For backup storage, vStor adds immutability controls at the snapshot and volume levels. Together, DPX, vStor, and GuardMode create a practical recovery path for Ubuntu systems: detect suspicious activity, preserve clean recovery points, and restore only what is needed.
- GuardMode monitoring for ransomware-like filesystem behavior
- Detection patterns, decoy files, entropy checks, and suspicious rename activity
- Immutable vStor snapshots and deletion lock policies
- MFA-controlled immutability operations
- Recovery from known clean restore points
- Storage replication and retention options for recovery planning

What Ubuntu file systems does DPX support?
For file-level backup, DPX supports most operating-system-supported file systems. Extended filesystem attributes are supported with EXT4, EXT3, EXT2, and XFS. For block backup, the listed file systems are EXT and XFS, with documented XFS limitations.
Does DPX support bare metal recovery for Ubuntu?
Yes, bare metal recovery is listed for supported Ubuntu versions. Implementation limits should be clear: the physical disk size on the target machine must be less than 2 TB, and devices using multipath are not compatible.
Does DPX support Ubuntu clusters?
No. Cluster support is not listed for Canonical Ubuntu in the current DPX compatibility data. Ubuntu cluster backup requirements should be reviewed with Catalogic before planning deployment.
How does DPX help protect Ubuntu backups from ransomware?
DPX can be paired with GuardMode for ransomware and anomaly detection and with vStor immutable backup storage. GuardMode monitors filesystem behavior for ransomware indicators, while vStor immutability helps protect backup snapshots and volumes against deletion or modification.
