Sql-server – limit to how many backup files I can restore from for a single database on RDS SQL Server

amazon-rdssql server

The AWS documentation for using native restore specifies that restoring from multiple files is allowed:

To avoid errors while restoring multiple files, make sure that all the
backup files have the same prefix, and that no other files use that
prefix.

The following example shows multiple-file restore.

exec msdb.dbo.rds_restore_database @restore_db_name='database_name',
@s3_arn_to_restore_from='arn:aws:s3:::bucket_name/bakup_file_*'

How many files can I restore from?
