Hello, Can you help me with my problem. I use this command line to backup my 500Gb database (INNODB). innobackupex --user=$BDD\_LOGIN --password=$BDD\_PASSWORD --compress $LATEST\_DIR --compress-threads=4 --parallel=2 --no-lock My problem is everyday after each backup I noticed an increase of 5Gb on my databasesize. Can you explain why? I did not have this problem with regular mysqldump. I assumed it may have something to do with fragmentation because I did not start my database with innodb\_file\_per\_table options but I am not sure. Regards, Geoffrey ---

I just find out ibdata1 cannot be fragmented. So I have absolutely no idea why my database keep growing after each backup. ---

Hi tdelnatte, could you give me the version of xtrabackup you are using and your MySQL version? Is the increase noticable only on ibdata1 and if so, you are talking about a sudden increase (autoextend) of the ibdata file?
