I found an old post about dbcopy on linux which suggetsed this

/opt/nove/groupwise/agents/bin/dbcopy -i `date --date='yesterday' +%m-%d-%Y`
/source /destination

Should it work??

When I try I get an error with dbcopy switches listed

Incremental copy would be nice?
Currently I'm deleting the destination once a week - which takes several
hours
