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.
