Lots of small files mean the drive will not reach the maximum write speed. So it could take hours to do so. Backing up lots of large files like databases means the data streams much faster (to the point of maximum speed for your LTO drive)...the only way to see is to run a backup.

Backing up to disk first and then duplicating to tape would be beneficial as you would then be duplicating larger files to tape, and also have faster restores on disk.
