}

func (*Archive) Create

func (a *Archive) Create(dest string, ctx context.Context) error

Creates an archive at dest with all of the files definied in the included files struct.

}

func (*ArchiveDetails) ToRequest

func (ad *ArchiveDetails) ToRequest(successful bool) api.BackupRequest

Returns a request object.

type Backup

type Backup struct {
	// The UUID of this backup object. This must line up with a backup from
	// the panel instance.
	Uuid string `json:"uuid"`

	// An array of files to ignore when generating this backup. This should be
	// compatible with a standard .gitignore structure.
	IgnoredFiles []string `json:"ignored_files"`
}

func (*Backup) Checksum

func (b *Backup) Checksum() ([]byte, error)

Returns the SHA256 checksum of a backup.

func (*Backup) Details

func (b *Backup) Details() *ArchiveDetails

Returns details of the archive by utilizing two go-routines to get the checksum and the size of the archive.

func (*Backup) Identifier

func (b *Backup) Ignored() []string

func (*Backup) Path

func (b *Backup) Path() string

Returns the path for this specific backup.

func (*Backup) Size

	// implementation is.
	Generate(*IncludedFiles, string) error

	// Returns the ignored files for this backup instance.
	Ignored() []string

	// Returns a SHA256 checksum for the generated backup.
	Checksum() ([]byte, error)

	// Returns the size of the generated backup.
	Size() (int64, error)

	// Returns the path to the backup on the machine. This is not always the final
	// storage location of the backup, simply the location we're using to store
	// it until it is moved to the final spot.
	Path() string

	// Returns details about the archive.
	Details() *ArchiveDetails

Generates a new S3 backup struct.

type S3Backup

type S3Backup struct {
	Backup

	// The pre-signed upload endpoint for the generated backup. This must be
