Without logminer (which I haven't used and don't know if that would really help anyway), I really don't think there is a way to grab that information from the log files.

You mentioned you don't have much freedom to change the doc management system, but if you really require this functionality you might have to. A simple date column saying when the file was checked in would suffice. Actually you could probablly do it without the date field, if the OS timestamp is the same as when the file was checked in.

One thing you'll need though is a log saying when the backups were done so you can create a series, and know when the previous backup was done so you can only take files newer then the latest backup.

For a basic example, say you take your first backup on Day 1.

For your second backup, on Day 5, every new file will have a date greater then Day 1. Copy only those files.

On your third backup, Day 10, you know to only take files with dates greater then Day 5.

It would be easiest with a date column inside Oracle, but if you really can't add that column you could do it with OS timestamps.
