From release 4.526/4.622, DBBACKUP and DYNABACK are essentially the same program. The only difference between them is that DBBACKUP opens the database in exclusive mode. For a complete list of command tails supported in 4.526/4.622 refer to DYNABACK.
Backs up the database to floppy disks or tape with option to also copy the transaction log file to disks. This program is mainly retained for compatibility with older releases. DYNABACK is an enhanced backup utility which can be run without interrupting normal operation and which can also check the integrity of your database and backups.
See Backing up a Database in the DP4 Developer's Manual for further information about backing up databases.
