Struct ShodhBackupEngine 

pub struct ShodhBackupEngine { /* private fields */ }

Backup engine for creating and managing backups

Implementations

impl ShodhBackupEngine

pub fn new(backup_path: PathBuf) -> Result<Self>

Create a new backup engine

Arguments

• backup_path - Directory to store backups

pub fn backup_path(&self) -> &Path

Get the backup storage path.

pub fn create_backup(&self, db: &DB, user_id: &str) -> Result<BackupMetadata>

Create a full backup of a RocksDB database

Arguments

• db - Reference to the RocksDB database
• user_id - User ID for the backup (or “all” for full system backup)

Returns

BackupMetadata with backup details

pub fn create_comprehensive_backup( &self, db: &DB, user_id: &str, secondary_stores: &[SecondaryStoreRef<'_>], ) -> Result<BackupMetadata>

Create a comprehensive backup of the main database, secondary stores, and graph.

Uses RocksDB BackupEngine for the main memories DB and Checkpoint API for secondary stores (todos, reminders, facts, files, feedback, audit) and the knowledge graph database.

pub fn create_comprehensive_backup_with_graph( &self, db: &DB, user_id: &str, secondary_stores: &[SecondaryStoreRef<'_>], graph_db: Option<&DB>, ) -> Result<BackupMetadata>

Create a comprehensive backup including the knowledge graph DB.

pub fn restore_backup( &self, user_id: &str, backup_id: Option<u32>, restore_path: &Path, ) -> Result<()>

Restore from a specific backup

Arguments

• user_id - User ID to restore
• backup_id - Backup ID to restore from (None = latest)
• restore_path - Path to restore the database to

pub fn list_backups(&self, user_id: &str) -> Result<Vec<BackupMetadata>>

List all available backups for a user

pub fn restore_comprehensive_backup( &self, user_id: &str, backup_id: Option<u32>, restore_path: &Path, secondary_restore_paths: &[(&str, &Path)], ) -> Result<Vec<String>>

Restore from a comprehensive backup, including secondary stores.

The secondary_restore_paths map store names to their target restore directories. Secondary stores are restored by copying the checkpoint directory to the target path.

pub fn purge_old_backups( &self, user_id: &str, keep_count: usize, ) -> Result<usize>

Delete old backups, keeping only the most recent N backups. keep_count must be >= 1 to prevent accidental deletion of all backups.

pub fn verify_backup(&self, user_id: &str, backup_id: u32) -> Result<bool>

Verify backup integrity using checksum
