What is BAK cubes ????

[gdimit]

Hi,
In my server there is a cube which its name is consisted from the "_BAK_" and a name of a other cube that we have Budget_Sales.
_BAK_Budget_Sales.
When the server starts I saw that there are some lines that say adding cube dependency.
3600 [] INFO 2016-06-22 06:59:52.699 TM1.Cube.Dependency Adding cube dependency: Cube 'Budget Sales' depends on cube '_BAK_Budget_Sales'.

How may I check why there is this dependency?
What is this cube?
Is it safe to remove it?

How may I check why there is this dependency?

It's because there is a rule reference from Budget_Sales to _BAK_Budget_Sales.

What is this cube?

Most likely a cube someone created to hold historical or backed up data.

Is it safe to remove it?

If you don't know for sure that it's safe then don't remove it.

The strange thing is that I can see this cube from Architect but not from the Performance modeler, thats why I am wondering if this is system cube

I'm not aware of any system generated cubes that would be a copy of an existing cube with the string "BAK", with underscores, inserted. Are you the TM1 administrator for this site? If not, have you asked the person who is what this cube is? If you are the administrator, how long has this cube been there? Did it just show up overnight? What about TI processes. Do you have any processes that could have created this cube?

It's a cube PM creates when you add/delete dimension to/from a cube (to copy data). Something went wrong (the whole PM is something wrong), and PM didn't delete it.
