Currently I have 6 database maintenance tasks firing off in one maintenance plan.
this plan runs once a week and has the following items
1) Check Database Integrity - all databases
2) Reorganize Index - all databases
3) Rebuild Index - all databases
4) Update Statistics - all databases
5) History Cleanup - all databases - keeping one month
6) Maintenance Cleanup Task - deletes bak files and trn files
Please advise if something is very wrong with doing all of these in one plan once a week.
