Remove archive log files in a production system

Hello,

We have a production system which generates a lot of archive log files (10 Mb size), we do a backup with a script (setting the table space to "backup mode" and using rsync command to copy), but we have a question.

1.- Can we remove the "old archive log files", for example, we have:

$ ls -l|more
total 94637712

This files are from 22 Ago and we don't need it. So the question is simple,

can we do a simple:

$ cp archv_1_46* /mnt/SOME_BACKUP_SERVER

$ rm archv_1_46*

to remove all files since 22 Ago TO 26 Ago?

2.- Which is the better, have too many archives (like we have with 10 Mb size) or one big archvive log file (with 600 Mb to copy into a CD)??

Thanks everybody
