For long-term storage of backup copies, use one storage location. You can also specify a shorter retention period for transaction logs compared to full backups.
For log shipping, use a different storage location with a significantly shorter retention period, such as 1 or 7 days (the storage locations can be the same—just use different directories in the same destination).
In future releases, we plan to improve the performance of our application to better handle a large number of transaction logs.
