The zmbkpose tool is a shell script that does hot backup and hot restore of ZCS Opensource accounts, GPL(OPENSOURCE). It can run from any host in the net, which means that it can be set on a backup server already existent.
In incremental_all_accounts(), when an user does not have previous full backup, $SESSION parameter is missing and the script is always doing full backup to such user.
In incremental_all_accounts(), when an user does not have previous full backup, $SESSION parameter is missing and the script is always doing full backup to such user.
Should be: backup_accounts $MAIL $SESSION
