The limiting factor with BlobBackup will be the number of files the storage backend can handle in one directory. Generally speaking BlobBackup will create slightly more files in your destination than your original source.

With object storage like s3, b2, azure, wasabi etc, this just isn't a problem since you can effectively have as many objects in one "directory" as you want.

With local, nas or hard drive storage, you'd be limited by the number of files per directory the file system allows (4.2 billion for NTFS for example). So you're probably fine here too.

Google drive (which isn't recommended for large backups with BlobBackup) has much stricter restrictions on files per directory. So really it depends on the backend but for most use cases it isn't a problem.

BlobBackup has been tested on millions of files backed up to NTFS and object storage yes.
