Can a transaction log be created without a backup?
In fact, backups of transaction logs cannot be created without having the full backup of data. Through Bulk or Full-logged recover mode, all the inactive transactions remain in the transaction log file after Checkpoint is processed and backup of transaction log is made.
Why is my log file so big after a backup?

Why does my transaction log file keep growing?
Its backup performs a truncation for inactive portion of transaction log that allows it to reuse it for the future transactions. This truncation does not shrink a file; it does not allow reusing the space in the file. Due to this, the transaction log file keeps on growing.
Why does the transaction log shrink after a backup?
The transaction log does not automatically shrink because you did a backup. This is actually a good thing because processes actually stop when the log grows. Your log has grown to the current size because you had processes that required the log to grow to that size.
