Refactor blob storage to use UUID primary keys and implement streaming chunking
- Changed blob table to use ID (UUID) as primary key instead of hash - Blob records are now created at packing start, enabling immediate chunk associations - Implemented streaming chunking to process large files without memory exhaustion - Fixed blob manifest generation to include all referenced blobs - Updated all foreign key references from blob_hash to blob_id - Added progress reporting and improved error handling - Enforced encryption requirement for all blob packing - Updated tests to use test encryption keys - Added Cyrillic transliteration to README

## Proposed: Store and Snapshot Commands
|
||||
|
||||
### Overview
|
||||
Reorganize commands to provide better visibility into stored data and snapshots.
|
||||
|
||||
### Command Structure
|
||||
|
||||
#### `vaultik store` - Storage information commands
|
||||
- `vaultik store info`
|
||||
- Lists S3 bucket configuration
|
||||
- Shows total number of snapshots (from metadata/ listing)
|
||||
- Shows total number of blobs (from blobs/ listing)
|
||||
- Shows total size of all blobs
|
||||
- **No decryption required** - uses S3 listing only
|
||||
|
||||
#### `vaultik snapshot` - Snapshot management commands
|
||||
- `vaultik snapshot create [path]`
|
||||
- Renamed from `vaultik backup`
|
||||
- Same functionality as current backup command
|
||||
|
||||
- `vaultik snapshot list [--json]`
|
||||
- Lists all snapshots with:
|
||||
- Snapshot ID
|
||||
- Creation timestamp (parsed from snapshot ID)
|
||||
- Compressed size (sum of referenced blob sizes from manifest)
|
||||
- **No decryption required** - uses blob manifests only
|
||||
- `--json` flag outputs in JSON format instead of table
|
||||
|
||||
- `vaultik snapshot purge`
|
||||
- Requires one of:
|
||||
- `--keep-latest` - keeps only the most recent snapshot
|
||||
- `--older-than <duration>` - removes snapshots older than duration (e.g., "30d", "6m", "1y")
|
||||
- Removes snapshot metadata and runs pruning to clean up unreferenced blobs
|
||||
- Shows what would be deleted and requires confirmation
|
||||
|
||||
- `vaultik snapshot verify [--deep] <snapshot-id>`
|
||||
- Basic mode: Verifies all blobs referenced in manifest exist in S3
|
||||
- `--deep` mode: Downloads each blob and verifies its hash matches the stored hash
|
||||
- **Stub implementation for now**
|
||||
|
||||
### Implementation Notes
|
||||
|
||||
1. **No Decryption Required**: All commands work with unencrypted blob manifests
|
||||
2. **Blob Manifests**: Located at `metadata/{snapshot-id}/manifest.json.zst`
|
||||
3. **S3 Operations**: Use S3 ListObjects to enumerate snapshots and blobs
|
||||
4. **Size Calculations**: Sum blob sizes from S3 object metadata
|
||||
5. **Timestamp Parsing**: Extract from snapshot ID format (e.g., `2024-01-15-143052-hostname`)
|
||||
6. **S3 Metadata**: Only used for `snapshot verify` command
|
||||
|
||||
### Benefits
|
||||
- Users can see storage usage without decryption keys
|
||||
- Snapshot management doesn't require access to encrypted metadata
|
||||
- Clean separation between storage info and snapshot operations

||||

// Snapshot Metadata Export Process
|
||||
// ================================
|
||||
//
|
||||
// The snapshot metadata contains all information needed to restore a backup.
|
||||
// Instead of creating a custom format, we use a trimmed copy of the SQLite
|
||||
// database containing only data relevant to the current snapshot.
|
||||
//
|
||||
// Process Overview:
|
||||
// 1. After all files/chunks/blobs are backed up, create a snapshot record
|
||||
// 2. Close the main database to ensure consistency
|
||||
// 3. Copy the entire database to a temporary file
|
||||
// 4. Open the temporary database
|
||||
// 5. Delete all snapshots except the current one
|
||||
// 6. Delete all orphaned records:
|
||||
// - Files not referenced by any remaining snapshot
|
||||
// - Chunks not referenced by any remaining files
|
||||
// - Blobs not containing any remaining chunks
|
||||
// - All related mapping tables (file_chunks, chunk_files, blob_chunks)
|
||||
// 7. Close the temporary database
|
||||
// 8. Use sqlite3 to dump the cleaned database to SQL
|
||||
// 9. Delete the temporary database file
|
||||
// 10. Compress the SQL dump with zstd
|
||||
// 11. Encrypt the compressed dump with age (if encryption is enabled)
|
||||
// 12. Upload to S3 as: snapshots/{snapshot-id}.sql.zst[.age]
|
||||
// 13. Reopen the main database
|
||||
//
|
||||
// Advantages of this approach:
|
||||
// - No custom metadata format needed
|
||||
// - Reuses existing database schema and relationships
|
||||
// - SQL dumps are portable and compress well
|
||||
// - Restore process can simply execute the SQL
|
||||
// - Atomic and consistent snapshot of all metadata
|
||||
//
|
||||
// TODO: Future improvements:
|
||||
// - Add snapshot-file relationships to track which files belong to which snapshot
|
||||
// - Implement incremental snapshots that reference previous snapshots
|
||||
// - Add snapshot manifest with additional metadata (size, chunk count, etc.)
