Maxdb incremental backup too large- impossible to be done

$

Hello

 

We have a ~2Tbytes Data Base MaxDB 7.9 that daily from Monday to Thursday is done a incremental backup to disk.

 

The usual incremental backup presents a 1.5 GB of data in disk.

 

This week we are experiencing a unusual behaviour that is a huge increase in the size of the incremental backup.

We have tried and the last incremental backup that we have tried and failed was 168 GB  which is 100 times greater than the usual and even this was not complete with success.

 

In the DB there is no error besides the error of space unavailable to perform the incremental backup.

The last week Friday night the Full Backup has run with success.

 

Does anyone have an idea what is the cause of this behaviour and how can we previously with any command knew the dimension of the incremental backup ?

 

Thanks

Best Regards

 

Sílvia
