Backup and Migrate exclusion recommendations? When doing database backup using Backup and Migrate, what is the reasonable table exclusion strategy?

My first guess was:


Exclude the following tables altogether - leave that listbox with no selection
Exclude the data from the following tables - select all tables that include "cache" word, such as cache_block or ctools_css_cache.


Any comments, any considerations, any recommendations?
I have following tables to exclude data (not to exclude the table altogether):


all cache_* tables
ctools_views_cache
ctools_object_cache
flood
history
queue
semaphore
watchdog
search_index


Usually search_index saves a lot of database size.
