Abstract
Methods for backup and recovery are disclosed. The method includes determining, based on attributes of at least one of one or more files included in data to be backed up, priorities of data blocks associated with the at least one file and storing the data to be backed up and indications of the determined priorities of the data blocks to a second storage device. The methods may determine data blocks that are more important for recovery while backing up data, so that backup data can be recovered faster in future.
