causing it to always run even with --force flag.
This is critical for NFS mounts with automatic capacity extension where
reported disk space is lower than actual available space.
Use case: Auto-extending NFS storage that shows limited capacity but
expands on demand.
- Check cluster metadata first before single DB metadata
- For cluster backups, mark as encrypted only if ANY database is encrypted
- Remove double confirmation requirement for --workdir in dry-run mode
- Fixes false positive 'encrypted backup detected' for unencrypted cluster backups
This allows --clean-cluster and --workdir flags to work correctly with unencrypted backups.
Implements cluster cleanup option for CLI (matches TUI functionality).
Features:
- --clean-cluster flag drops all user databases before restore
- Preserves system databases (postgres, template0, template1)
- Shows databases to be dropped in dry-run mode
- Requires --confirm for safety
- Warns user with 🔥 icon when enabled
- Can combine with --workdir for full disaster recovery
Use cases:
- Disaster recovery scenarios (clean slate restore)
- Prevent database conflicts during cluster restore
- Ensure consistent cluster state
Examples:
# Disaster recovery
dbbackup restore cluster backup.tar.gz --clean-cluster --confirm
# Combined with workdir
dbbackup restore cluster backup.tar.gz \
--clean-cluster \
--workdir /mnt/storage/restore_tmp \
--confirm
Chef's kiss backup tool! 👨🍳💋
Sanitized all production-specific paths:
- /u01/dba/restore_tmp → /mnt/storage/restore_tmp
- /u01/dba/dumps/ → /mnt/backups/
Changed in:
- cmd/restore.go: Help text and flag description
- internal/restore/safety.go: Error message tip
- README.md: All documentation examples
- bin/*: Rebuilt all platform binaries
This ensures no production environment paths are exposed in public code/docs.
Replaced actual production database names with generic examples:
- test00, teststablekc, keycloak, stabledc → myapp_production, myapp_analytics, users_db, inventory_db, reports_db
- Updated archive filenames to generic examples
- Changed dates to generic future dates
- Adjusted database counts (7 → 5)
- Modified file sizes to be more generic
This ensures no production-specific information is exposed in public documentation.
Completed TUI documentation with missing screens:
- Database Status & Health Check:
* Connection status with checkmark
* Database info (type, host, port, user, version)
* Backup directory location
* Database count
* Health status indicator
- Backup Archive Manager (List & Manage):
* Total archives and size summary
* Sortable table with filename, format, size, date
* Status indicators (✓ valid, ⚠ old, ✗ invalid)
* Cursor navigation
* Keyboard shortcuts for restore/verify/info/delete/refresh
All TUI screens now documented accurately!
Replaced outdated backup progress view with actual TUI implementation:
- Backup Execution (in progress):
* Shows type, database, duration
* Spinner animation with status message
* Cancel instruction
- Backup Completed (success):
* Completion status with checkmark
* Backup details (filename, size, location, databases)
* SHA-256 verification confirmed
* Return to menu instruction
Removed old progress bar style (45%, ETA, Speed) that's not in current TUI.
Now accurately reflects the actual backup execution screen.
Added missing TUI screen examples for restore operations:
- Restore Preview screen showing:
* Archive information (file, format, size, date)
* Cluster restore options with existing databases list
* Safety checks with status indicators (✓/✗/⚠)
* Cleanup warning when enabled
* Keyboard shortcuts
- Restore Progress screen showing:
* Current phase and status with spinner
* Database being restored with size
* Elapsed time
* Cancel instruction
Both screens match actual TUI implementation.
Enhanced documentation for --workdir flag:
- Added to Cluster Restore command reference section
- Added example to restore examples with clear "special case" comment
- Explained use case: VMs with small system disk but large NFS mounts
- Clarified it's NOT needed for standard deployments
- Prevents confusion about when to use this flag
Updated to match actual TUI implementation:
- Shows all 13 configuration fields with current values
- Includes database type cycling (PostgreSQL/MySQL/MariaDB)
- Shows Current Configuration summary section
- Displays keyboard shortcuts (↑/↓ navigate, Enter edit, 's' save, 'r' reset, 'q' menu)
- Matches screenshot appearance
The interactive menu display was outdated. Updated to match current implementation:
- Shows database engine switcher (PostgreSQL/MySQL/MariaDB)
- Lists all 13 menu options with separators
- Includes new features: Sample backup, Cluster operations, Active operations, History
- Matches actual TUI appearance from screenshots
Solves disk space issues on VMs with small system disks but large NFS mounts.
Use case:
- VM has small / partition (e.g., 7.8G with 2.3G used)
- Backup archive on NFS mount (e.g., /u01/dba with 140G free)
- Restore fails: "insufficient disk space: 74.7% used - need at least 4x archive size"
Solution:
- Added --workdir flag to restore cluster command
- Allows specifying alternative extraction directory
- Interactive confirmation required for safety
- Updated error messages with helpful tip
Example:
dbbackup restore cluster backup.tar.gz --workdir /u01/dba/restore_tmp --confirm
This is environmental, not a bug. Code working brilliantly! 👨🍳💋

Status: Build successful, ready for testing
- Added encryption flags to restore commands (--encryption-key-file, --encryption-key-env)

- Auto-detects encrypted backups via IsBackupEncrypted()
- Decrypts in-place before restore begins
- Tested: Encryption/decryption roundtrip validated successfully
- Phase 4 (AES-256-GCM encryption) now COMPLETE
All encryption features working:
✅ Backup encryption with --encrypt flag
✅ Restore decryption with --encryption-key-file flag
✅ Key loading from file or environment variable
✅ Metadata tracking (Encrypted bool, EncryptionAlgorithm)
✅ Roundtrip test passed: Original ≡ Decrypted
Implemented full incremental backup creation:
internal/backup/incremental_postgres.go:
- CreateIncrementalBackup() - main entry point
- Validates base backup exists and is full backup
- Loads base backup metadata (.meta.json)
- Uses FindChangedFiles() to detect modifications
- Creates tar.gz with ONLY changed files
- Generates incremental metadata with:
- Base backup ID (SHA-256)
- Backup chain (base -> incr1 -> incr2...)
- Changed file count and total size
- Saves .meta.json with full incremental metadata
- Calculates SHA-256 checksum of archive
internal/backup/incremental_tar.go:
- createTarGz() - creates compressed archive
- addFileToTar() - adds individual files to tar
- Handles context cancellation
- Progress logging for each file
- Preserves file permissions and timestamps
Helper Functions:
- loadBackupInfo() - loads BackupMetadata from .meta.json
- buildBackupChain() - constructs restore chain
- CalculateFileChecksum() - SHA-256 for archive
Features:
✅ Creates tar.gz with ONLY changed files
✅ Much smaller than full backup
✅ Links to base backup via SHA-256
✅ Tracks complete restore chain
✅ Full metadata for restore validation
✅ Context-aware (cancellable)
Status: READY FOR TESTING
Next: Wire into backup engine, test with real PostgreSQL data
Added CLI integration for incremental backups:
cmd/backup.go:
- Added --backup-type flag (full/incremental)
- Added --base-backup flag for specifying base backup
- Updated help text with incremental examples
- Global vars to avoid initialization cycle
cmd/backup_impl.go:
- Validation: incremental requires PostgreSQL
- Validation: incremental requires --base-backup
- Validation: base backup file must exist
- Logging: backup_type added to log output
- Fallback: warns and does full backup for now
Status: CLI READY but not functional
- Flag parsing works
- Validation works
- Warns user that incremental is not implemented yet
- Falls back to full backup
Next: Implement CreateIncrementalBackup() and RestoreIncremental()
Added cloud storage configuration to TUI settings interface:
- Cloud Storage Enabled toggle
- Cloud Provider selector (S3, MinIO, B2, Azure, GCS)
- Bucket/Container name configuration
- Region configuration
- Access/Secret key management with masking
- Auto-upload toggle
Users can now configure cloud backends directly from the
interactive menu instead of only via command-line flags.
Cloud auto-upload works when CloudEnabled + CloudAutoUpload
are enabled - backups automatically upload after creation.
