Hi!!!
You could consider using a more efficient backup method, such as rsync, which only transfers the differences between the source and destination instead of the entire file. Additionally, you can schedule regular incremental backups using cron jobs to save time and resources. Another option is to use a cloud-based backup solution, such as AWS S3 or Google Cloud Storage, to store your backups securely in the cloud. Finally, it's important to also keep multiple backups stored in different locations for disaster recovery purposes.
