Is it ok to delete files from my backup files?

Yes, it's generally okay to delete files from your backup if you're certain that you no longer need them or have alternative copies stored elsewhere. However, be cautious and ensure that you don’t remove anything important, as backups are meant to provide security against data loss. It’s advisable to keep a consistent backup strategy and periodically review what you have stored. Always have at least one reliable backup before making deletions.
