You only have to call this program when storeBackup.pl tells you to do so.
This program converts old backups created with storeBackup.pl to the newest version.
The current version of the backup format is 1.3.
You can see the version by typing:
head -1 < ...<storeBackupDir>/date_time/.md5CheckSums.info
Call storeBackupConvertBackup.pl with the backup directories to convert:
