Backups are easy to promise and painful to rely on if they’re not designed and tested correctly. In an analytic warehouse, where data volumes are large and SLAs are tight, backup and restore (BAR) strategy is a key part of your risk posture.

Yellowbrick’s BAR2 framework gives you the building blocks—you supply the strategy.

The three building blocks: full, cumulative, incremental

Yellowbrick supports:

• Full backups
  • Complete copy of the database
  • Foundation for all subsequent backups in a chain
• Cumulative backups
  • Capture all changes since the last full or cumulative
  • Simplify restores because fewer pieces are needed
• Incremental backups
  • Capture changes since the last full, cumulative, or incremental
  • Provide fine‑grained restore points with optimal storage usage

All three have their place; the art is combining them.

Strategy 1: Monthly full + daily cumulative

This is often a great starting point for many enterprises.

Typical pattern:

• Take a full backup at the beginning of the month
• Take cumulative backups every day
• For a restore, apply:
  • The monthly full backup
  • The cumulative backup for the desired day

Pros:

• Simple mental model
• Fewer restore steps than a purely incremental chain

Cons:

• Uses more storage than strategies that lean heavily on incrementals

Strategy 2: Monthly full + daily incremental + weekly cumulative

When storage and flexibility both matter, this hybrid approach can be ideal.

Typical pattern:

• Take a full backup at the beginning of the month
• Take incremental backups daily
• Take a cumulative backup weekly
• After each successful weekly cumulative, purge older incrementals from that week

Pros:

• More restore points available without keeping every incremental forever
• Balanced storage consumption and restore complexity

Cons:

• Requires disciplined management and clear automation/documentation

Managing backup chains like a product, not a script

Regardless of strategy, healthy backup chains share traits:

• Visibility:
  • Regularly list backups and verify chain integrity
  • Track backup sizes and timings for capacity planning
• Hygiene:
  • Purge invalid or obsolete backups using supported tools
  • Fix bundle paths if backups are relocated between storage systems
• Documentation:
  • Clear, current runbooks for backup and restore procedures
  • Ownership assigned within your team

This turns backups from “that script in cron” into a managed capability.

Restore tests: the real measure of readiness

• Schedule periodic restores into non‑production databases
• Validate:
  • Data integrity and completeness
  • Application behavior against restored copies
  • Handling of security objects (users, roles, privileges) per your policies
• Measure how long restores take versus your RTO expectations

Teams that build restore tests into their regular operations sleep better when something goes wrong, because they’ve already rehearsed what to do.
