SSAS: restore last good cube on failed processing

Hi all,

I have a cube that I process every day. I do this daily because transaction data is added and reference data is changed (new/modified products etc.).

First question - it IS right to process the dimensions and the cube daily isn't?

Sometimes, users enter bad data (we are still working on better validation) which causes the processing to fail rendering the cube useless to the regular users.

Main question - is there a method to and a backup for rollback if the processing fails? Data 48hrs is better than no data.

Thanks,

Warren

Hi,

If your data comes daily - it is natural to process both your dimensions and cubes daily. Yes.

Most of my own cubes are on top of data warehouses. ETL takes care of data quality - each fact row has corresponding row in the dimension. Depending on the fact the 'bad' row has value 0 (missing) or is neglected totally and written to the error table during ETL.

Cube backup and restore you'll find in SQL Management studio when you connect to SSAS. Right click your SSAS database - if you want to do it manually.

Backups can also be automated. See:
