Hi Evgenii,

Individual backup of each database or group of databases is possible through a custom routine. Below is the code of one of the routine we used long time back to split database backup to multiple disks. You just need to mention database names in each dblist. But as Dmitriy mentioned external backup (snapshot) is the best approach to follow.

     // Start Backup of Individual Enviroments
    do dblist1           //Backup DB-A, DB-B, DB-C (do dblist1^ZBACKUP)
    do dblist2           //Backup DB-D, DB-E (do dblist2^ZBACKUP)     
    do dblist3        //Backup DB-F, DB-G, DB-H, DB-I (do dblist3^ZBACKUP)
    quit
