[Borgbackup] question about deduplicated size stats

[Maurice Libes]

hi to all
just a question

yesterday I made a backup here below, the deduplicated size was 103.49G

Archive name:/*baklouti-homes-2017-09-11*/
Time (start): Mon, 2017-09-11 12:27:09
Time (end):   Mon, 2017-09-11 16:41:53
Duration: 4 hours 14 minutes 44.46 seconds
Number of files: 768993
------------------------------------------------------------------------------
                        Original size      Compressed size    Deduplicated size
This archive:/*  347.38 GB            139.32 GB            103.49 GB*/
All archives:              347.38 GB            139.32 GB            103.49 GB

                        Unique chunks         Total chunks
Chunk index:                  695181               864806
------------------------------------------------------------------------------

in the night there have been another backup /*baklouti-homes-2017-09-12*/

but if I want to display again the stats of the same backup of yesterday 
*/baklouti-homes-2017-09-11/* with a borg info command, now it displays 
/*39.20MB*/

why the size have changed ?
thanks
ML
