Implementations

impl BackupManager

pub fn new(backup_dir: impl AsRef<Path>) -> Result<Self>

Create a new BackupManager with the given backup storage directory.

Creates the directory if it does not exist.

pub fn create_backup(&self, source_dir: &Path) -> Result<BackupMetadata>

Create a full backup of the source data directory.

Copies all files recursively from source_dir into a new backup subdirectory, calculates a CRC32 checksum, and writes metadata.

pub fn restore_backup( &self, backup_id: &str, target_dir: &Path, ) -> Result<BackupMetadata>

Restore a backup to the given target directory.

Verifies backup integrity before restoring. If target_dir already exists, it is cleared first.

pub fn list_backups(&self) -> Result<Vec<BackupMetadata>>

List all available backups sorted by creation time (newest first).

pub fn delete_backup(&self, backup_id: &str) -> Result<()>

Delete a backup and all its data.

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

Verify backup integrity by recalculating the CRC32 checksum.

Returns true if the checksum matches, false otherwise.

pub fn backup_size(&self, backup_id: &str) -> Result<u64>

Get the total size in bytes of a backup (data files only).
