pub fn backup_namespace( &self, namespace_id: &NamespaceId, backup_name: &str, ) -> Result<()>

Create a backup of a namespace

This creates a snapshot of the namespace’s VecStore and saves it.

• backup_name - Name for the backup

Returns

• Ok(()) if backup was created successfully
• Err if namespace doesn’t exist or backup fails

pub fn restore_namespace( &self, namespace_id: &NamespaceId, backup_name: &str, ) -> Result<()>

Restore a namespace from a backup

This restores a namespace from a previously created snapshot.

Arguments

• namespace_id - ID of the namespace to restore
• backup_name - Name of the backup to restore from

Returns

• Ok(()) if restore was successful
• Err if namespace doesn’t exist or restore fails

pub fn list_namespace_backups( &self, namespace_id: &NamespaceId, ) -> Result<Vec<(String, String, usize)>>

Arguments

• namespace_id - ID of the namespace

Returns

• List of (snapshot_name, created_at, record_count) tuples

pub fn delete_namespace_backup( &self, namespace_id: &NamespaceId, backup_name: &str, ) -> Result<()>

Delete a backup for a namespace

Arguments

• namespace_id - ID of the namespace
• backup_name - Name of the backup to delete
