Hi,

>I can do regular backup with gbak but i look for some smarter solution

to.


To backup any of the databases with VM snapshots or similar mechanisms a
series of special preparation and post-backup steps must be fulfilled,
or database should be in "archivelog" (Oracle) mode.

You can use nbackup to lock database before VM snapshot, in this case
only delta will be at risk.

However, nbackup-only solution is not smart, since it does check an
integrity of database, as gbak does.
We recommend to use combination of nbackup and gbak.
