Code:
0 0 * * 0,3 cp .bash_history boo_$(date +%Y%m%d)

But if you specifically want _1, _2 etc. you can write a small script to get the latest boo_* file, then cut the string after '_' , add 1 to that cut string as it would be a number, and create file with that name...

Put that shell script in cron
Thx. Could you also explain how to write that script?
