Variables

var DefaultModes = Modes{Dir: 0700, File: 0600}

DefaultModes defines the default permissions to apply to new repository files and directories stored on file-based backends.

Functions

func DefaultDelete

func DefaultDelete(ctx context.Context, be backend.Backend) error

DefaultDelete removes all restic keys in the bucket. It will not remove the bucket itself.

func DefaultLoad

func DefaultLoad(ctx context.Context, h backend.Handle, length int, offset int64,
	openReader func(ctx context.Context, h backend.Handle, length int, offset int64) (io.ReadCloser, error),
	fn func(rd io.Reader) error) error

DefaultLoad implements Backend.Load using lower-level openReader func

func IsErrDot

func IsErrDot(err error) bool

func StartForeground

func StartForeground(cmd *exec.Cmd) (bg func() error, err error)

StartForeground runs cmd in the foreground, by temporarily switching to the new process group created for cmd. The returned function `bg` switches back to the previous process group.

The command's environment has all RESTIC_* variables removed.

Types

type LimitedReadCloser

type LimitedReadCloser struct {
	io.Closer
	io.LimitedReader
}

LimitedReadCloser wraps io.LimitedReader and exposes the Close() method.

func LimitReadCloser

func LimitReadCloser(r io.ReadCloser, n int64) *LimitedReadCloser

LimitReadCloser returns a new reader wraps r in an io.LimitedReader, but also exposes the Close() method.

type Modes

type Modes struct {
	Dir  os.FileMode
	File os.FileMode
}

func DeriveModesFromFileInfo

func DeriveModesFromFileInfo(fi os.FileInfo, err error) Modes

DeriveModesFromFileInfo will, given the mode of a regular file, compute the mode we should use for new files and directories. If the passed error is non-nil DefaultModes are returned.
