How dump database cumulative works?

Hi,

I have some doubts about how the dump database cumulative command works,

I guess that the changes perfomed after a dump database full are registered ( not in the syslogs table) and when you send a dump database cumulative ase backup those changes.

I want to know if I can use this command in a database that has the options "trunc log on chkpt" and "select into/bulkcopy/pllsort" set?

Regards,

Luz Rodriguez

    Hi,

    Just for the record (for others people reading the thread 😊 ), the "trunc log on ckpt" and "select into/bulkcopy/pllsort" database options shouldn't be enabled when using ASE on SAP Business Suite environment, which are the default settings actually (see also SAP Note 1581695 and 1749935 - Configuration Guides for SAP ASE 16 and 15.7 ). You then can use cumulative database dump option, just be sure to set database option "allow incremental dumps". To check the history of a cumulative dump using sp_dump_history

    Luz,

    I don't think you can ever perform incremental backups when the "truncate log on checkpoint" options is turned on in any database.

    If my understanding of the cummulative database backup functionality in the latest releases of ASE is correct, I believe it relies on the same principles to perform the backup, hence the answer would be, NO, you cannot perform cummulative database backups on a database which has the "truncate log on checkpoint" option turned on.It would be easy enough to create a small database and verify it...

    As far as the "select into/bulkcopy/pllsort" option, I don't believe it has ever had a role in the backup process.
