[To Design] backup #2

Closed yinweiishere closed 7 years ago

yinweiishere commented 8 years ago

backup includes steps:

  1. create a special snapshot, say, backup-snap-x;
  2. find last backup-snap-(x-1), check if this snapshot has been synchronized to remote;
  3. calc delta data between backup-snap-x and backup-snap-(x-1);
  4. transfer the delta data.
