In addition to the default settings, you should check the box to:
Cancel the operation after 5 attempts.
If any Client remains connected, with an open transaction, the Backup will not commence. Your settings should allow the Backup to Cancel after a reasonable number of attempts.
Keep only the last 3 backup files, protects you from running out of disk space
Backup only if the data file has been modified, won't make redundant copies on the weekend
Delete the oldest backup file [after] backup, is safer than before
If active transactions or index operations, Abort or you may wait into the next business day and block users from working.
If backup fails, and you Retry after  Minutes be sure to
Cancel the operation after  attempts.
