Functions

func ParseConfig

func ParseConfig(s string) (interface{}, error)

ParseConfig parses a local backend config.

Types

type Config

type Config struct {
	Path   string
	Layout string `option:"layout" help:"use this backend directory layout (default: auto-detect)"`

	Connections uint `option:"connections" help:"set a limit for the number of concurrent operations (default: 2)"`
}

Config holds all information needed to open a local repository.

func NewConfig

func NewConfig() Config

NewConfig returns a new config with default options applied.

type Local

type Local struct {
	Config

	layout.Layout
	backend.Modes
	// contains filtered or unexported fields
}

Local is a backend in a local directory.

func Create

func Create(ctx context.Context, cfg Config) (*Local, error)

Create creates all the necessary files and directories for a new local backend at dir. Afterwards a new config blob should be created.

func Open

func Open(ctx context.Context, cfg Config) (*Local, error)

Open opens the local backend as specified by config.

func (*Local) Close

func (b *Local) Close() error

Close closes all open files.

func (*Local) Connections

func (b *Local) Connections() uint

func (*Local) Delete

func (b *Local) Delete(ctx context.Context) error

Delete removes the repository and all files.

func (*Local) HasAtomicReplace

func (b *Local) HasAtomicReplace() bool

HasAtomicReplace returns whether Save() can atomically replace files

func (*Local) Hasher

func (b *Local) Hasher() hash.Hash

Hasher may return a hash function for calculating a content hash for the backend

func (*Local) IsNotExist

func (b *Local) IsNotExist(err error) bool

IsNotExist returns true if the error is caused by a non existing file.

func (*Local) List

func (b *Local) List(ctx context.Context, t restic.FileType, fn func(restic.FileInfo) error) (err error)

List runs fn for each file in the backend which has the type t. When an error occurs (or fn returns an error), List stops and returns it.

func (*Local) Load

func (b *Local) Load(ctx context.Context, h restic.Handle, length int, offset int64, fn func(rd io.Reader) error) error

Load runs fn with a reader that yields the contents of the file at h at the given offset.

func (*Local) Location

func (b *Local) Location() string

Location returns this backend's location (the directory name).

func (*Local) Remove

func (b *Local) Remove(ctx context.Context, h restic.Handle) error

Remove removes the blob with the given name and type.

func (*Local) Save

func (b *Local) Save(ctx context.Context, h restic.Handle, rd restic.RewindReader) (err error)

Save stores data in the backend at the handle.

func (*Local) Stat

func (b *Local) Stat(ctx context.Context, h restic.Handle) (restic.FileInfo, error)

Stat returns information about a blob.
