Implementations

impl Backup

pub async fn prepare<D: AsRef<Path>>(backup_dir: D) -> Result<Self, BackupError>

Creates the destination directory and the WAL archive directory if these do not exist, and allocates a temporary location for the base backup.

pub async fn do_configure_archiving( &self, resource: &HeldResource, archive_command: &str, ) -> Result<bool, BackupError>

Configures the cluster for continuous archiving.

Returns a flag indicating if the cluster must be restarted for changes to take effect. If the cluster is already configured appropriately, this does nothing (and returns false).

pub async fn do_base_backup( &self, resource: &HeldResource, ) -> Result<PathBuf, BackupError>

Performs a “base backup” of the cluster.

Returns the directory into which the backup has been created. This is always a subdirectory of [self.backup_dir].

This must be performed after configuring continuous archiving (see Backup::do_configure_archiving).

Trait Implementations

impl Debug for Backup

fn fmt(&self, f: &mut Formatter<'_>) -> Result
