Hi
Greetings!!
We use Apache Derby - 10.10.1.1. We do backup using procedure call “CALL SYSCS_UTIL.SYSCS_BACKUP_DATABASE”
We do have cron jobs scheduled to take up the back up every day on the specified time. We found that the size of backup files bigger that actual database files.

Actual DB
-----------
-bash-3.2# du -sh /opt/CSCOppm-unit/data/ppm_data/blobs/
2.3G /opt/CSCOppm-unit/data/ppm_data/blobs/

Backup
-----------
-bash-3.2# du -sh /opt/ppm17-Unit-ppm-ucs-vm38-dbdata-backup/data/ppm_data/blobs/
4.2G /opt/ppm17-Unit-ppm-ucs-vm38-dbdata-backup/data/ppm_data/blobs/

Could you please help on this issue.
