How to delete backups successfully that are 5 years old.

NBU Version:  7.1.0.3

I found some old backups that I want to delete but want to ensure that I do it properly.

After running this command I found one client that has backup images that are 5 years old.

>ls -ltr `find . -name '<client name>*'` | more

>rm Rf `find . -name '<client name>*'` | more

Thanks for you help!
