Resolution

/var/log/lastlog is a sparse file. A sparse file is a file that contains unallocated blocks or “empty space”, as it implies, it does not actually take up filesystem space.

The size of the file /var/log/lastlog can appear to be overly large on some systems, most especially in 64 bit architectures.

The following command shows the actual size of the lastlog file.
# ls -lh  /var/log/lastlog

Solution :
Exclude the file(/var/log/lastlog) from the backup selection.
