First, any backup implementation should have recovery point and time objective.
Next, there’s no right or wrong, just what fits the requirements.
FILESPERSET controls maximum number of files for each backupset.
MAXPIECESIZE controls maximum size of backuppiece.
MAXSETSIZE controls maximum size of backupset.
Typically, if MAXSETSIZE is set, it should be equal to or greater than maximum size of all data files.
In general, it is not recommended to set MAXSETSIZE.
Backupset can contains 1 or more backuppiece; hence, why set a limitation on maxsetsize when it may be better to set limitation for maxpiecsize?
Justification for filesperset=1 is faster recovery and filesperset>1 is to reduce management of backup, e.g. crosscheck.
Consideration, backup versus restore frequencies.
Here’s an analogy, you are at bank withdrawing $2000 and the teller ask, how do you want the bill?
Would you like 20 $100 bills or multiple small bills 1,5,10,20 or combination of there of?
Same concept applies to backupset and filesperset.
Note: FILESPERSET and MAXOPENFILES affect multiplexing, number of buffers, size of each buffer and is not the scope of this blog post.
Actual results for TB size DB.
Note: the objective is not to improve backup time performance but to reduce number of backuppiece.
