Incremental for monday until thursday and full backup on friday

Dear BE froum members,

I'm new at BE, and I need your advices regarding BE.

I got order to create backup job in BE 2012.

We have single tape drive and BE 2012.

I want the cartridge not ejected.

For the backup setting is Incremental from Monday until Thursday and Full backup on Friday.

I want to keep the data for 7 days backward.

Then overwrite the expire media.

My plan for this job are:

Media set: OPP 6 days and AP 1 hour.

And 'When this job begins': Overwrite.

Is it correct?

Thank you in advance.
