understanding "delete all input" and options such as "before 'SYSDATE-1' "

I am running Oracle 11.2 on Solaris 10.

My question is regarding the options with backing up archivelogs.
My objective here is to leave archivelogs that have been backed up nightly on the server for an additional 24 hours after backing them up. (The reason is for our standby database in case I have to rebuild it and to have the archivelogs handy without restoring them.)

My current backup statement for archive logs is:
 archivelog all
 delete all input
 format '$DESTDIR/';
I considered to add *before 'SYSDATE-1' to the above statement as follows:
 delete all input before 'SYSDATE-1'
Would this keep the archivelogs on the server for additional day?
And, would it delete the archives automatically that would be older than one day?

I also have the following lines after my main backups run:
run {
crosscheck backup;
crosscheck copy;
delete noprompt expired backup;
crosscheck archivelog all;
delete noprompt archivelog all completed before 'SYSDATE-1';   <==========
#delete noprompt force obsolete DEVICE TYPE disk;
