Functions

func CreateSnapshot

func CreateSnapshot(subvolume string, snap domain.Snapshot) (uint64, error)

CreateSnapshot creates a new snapshot.

func DeleteSnapshot

func DeleteSnapshot(ph string) error

DeleteSnapshot deletes existing snapshot by path. These here we use exec.Command because for some reason `btrfs.SubvolDelete` is waiting for the response and it looks not convenient from UI perspective.

func GetSubvolID

func GetSubvolID(ph string) (uint64, error)

func GetVolumeIDByPath

func GetVolumeIDByPath(ph string) (uint64, error)

func Restore

func Restore(snapPath, mountPoint string) error

Restore creates a new snapshot. The idea is not to just move snapshot data to subvolume (like @ or @home) but make a snapshot for it.

func SupportedByKernel

func SupportedByKernel() (bool, error)

SupportedByKernel checks if kernel supports btrfs.
