Can you provide steps, how you took the backup? command line? Are you sure that backup was completed successfully?
As per the log,

InnoDB: The error means the system cannot find the path specified.
xtrabackup: Warning: cannot open ./xtrabackup_logfile. will try to find.
xtrabackup: 'ib_logfile0' seems to be 'xtrabackup_logfile'. will retry.
Are you sure all files are properly untar from the backup? it seems above files are not there and backup is corrupted.
