DPX feature
Block Backup
Protect large, fast-changing data sets without repeatedly copying every file. Catalogic DPX Block Data Protection captures complete point-in-time recovery images, then transfers only changed blocks after the initial backup.
Efficient protection at the block level
File-by-file backup can create long windows when servers and databases contain millions of files or frequently changing data. DPX Block Data Protection works below the file system, protecting data in blocks from primary NetApp storage and Windows, UNIX, or Linux systems to secondary storage. The first run creates a base backup. Each later incremental transfers only blocks that changed, while every recovery point remains a virtual image of the entire source volume at that moment.
One backup image, multiple recovery paths
DPX block backups support recovery at the level the incident demands, from one file to a complete system.
Changed-block incrementals
After the initial base backup, DPX transfers only changed blocks to reduce repeated data movement and keep recurring backups efficient.
Point-in-time recovery
Each base or incremental instance represents the entire protected volume at a specific point in time, giving teams clear recovery choices.
Granular file restore
Restore individual files and directories from a block backup when rebuilding the whole volume would be unnecessary.
Instant Access
Map a recovery point as a writable network disk so data can be accessed, copied, verified, or put to use without changing the original backup.
Application recovery
Use application-aware block protection and restore workflows for supported business applications including Microsoft SQL Server and Oracle Database.
Bare metal recovery
Use block-level protection as the foundation for recovering supported Windows and Linux systems when the operating system or hardware must be rebuilt.
Protect physical systems and critical applications
DPX Block Data Protection is built for workloads where backup efficiency and recovery flexibility both matter:
- Protect supported Windows, Linux, and UNIX systems with agent-based block-level backup.
- Back up primary NetApp storage to supported secondary storage systems.
- Capture System State and System Table data as part of supported block backup workflows.
- Protect application data for supported Microsoft SQL Server, Oracle, Exchange, SharePoint, and SAP HANA environments.
- Keep multiple point-in-time recovery images without running another full backup for every scheduled job.
Verify recovery points before you need them
With vStor as the backup destination, DPX can automatically verify supported block backups after a job completes. vStor mounts the backup snapshot to confirm that its data can be accessed. Teams can also enable an automated GuardMode scan after successful verification to look for suspicious files and add ransomware awareness to recovery-point selection.
Fast recovery without sacrificing precision
DPX block backups provide several recovery modes for different outage scenarios:
- Restore one or more files or directories from an agent-based block backup.
- Map a selected recovery point with Instant Access and browse the data directly.
- Virtualize a supported block backup as a temporary or production virtual machine.
- Recover supported application data with application-specific restore workflows.
- Restore protected block data to primary NetApp storage or open systems from secondary storage.
Block backup questions, answered
How does DPX block backup work?
The first backup of a selected volume is a base backup. Later backups are incremental and transfer only blocks that changed. Each recovery point is presented as a virtual image of the complete source volume at that point in time.
What systems can DPX protect with block backup?
DPX supports block-level protection from primary NetApp storage and supported Windows, UNIX, and Linux systems to secondary storage. Check the current DPX documentation and compatibility guide for version-specific platform and application requirements.
Can I restore individual files from a block backup?
Yes. DPX can restore individual files and directories from block backups. Instant Access can also map a recovery point for direct browsing and writable access while leaving the original backup unchanged.
Can DPX verify block backups automatically?
Yes, for supported block backups stored on vStor. DPX can have vStor mount the snapshot after backup to confirm the data is accessible. File-system restrictions apply, so review the backup verification documentation when planning jobs.
How is block backup different from file backup?
File backup protects selected data by file and directory. Block backup protects the underlying volume in blocks, making it a strong fit for large or frequently changing data sets and full-system recovery. DPX still lets you recover individual files from a block backup when granular restore is the right response.
